| Recent Backup and Recovery Articles from free-backup.info What is an Online Backup? Andrew Whitehead is a contributor at Free-backup.info -- the home of the popular Amazon S3 based software for online data backup -- Back2zip. This article can be found at http://free-backup.info/what-is-an-online-backup.html What is an Online Backup?An online backup offers an alternative to optical or tape backup solutions. While traditional methods can be very effective, they require capital to set up and staff to operate them. An online backup system avoids these problems.Online Backup Works Like ThisThe online backup provider supplies a software agent to be installed on the computer to be backed up. This busy piece of software allows the user to select the files to be backed up, manages the internet connection, encrypts and compresses the data before transferring it across the internet to a secure, remote location, and allows the user to view and restore the backed up documents.The Benefits of Online BackupOnline backups offer several advantages. The main one is the disaster recovery offered by offsite storage but there are also several advantages in terms of ease of use. No capital outlay is required for purchasing new equipment. There are no ongoing media costs or staff costs, running costs are limited to paying a monthly fee. Setup and installation is a simple matter of downloading the software, and takes only a few minutes to set up. Data recovery is equally fast, as there is no searching for the right tape or waiting for IT staff to recover lost data. The backup process itself is completely automated which ensures that it gets done, and the backed up files can then be accessed by anyone with permission, allowing file sharing with traveling colleagues, clients, or home PCs.The Limitations of Online BackupAn intrinsic characteristic of online backup is that it relies on an internet connection. For smaller data volumes a dial-up connection may be adequate, but permanent broadband connection able to handle significantly larger volumes is a necessity in most cases. Whatever type of connection is used, the initial backup will take a long time. A complete copy of the data must be encrypted, compressed, and copied. This initial copy could possibly be unrealistically long if a large amount of data is being sent over a dial up connection, although most online backup providers will allow the user to break off and resume the backup later. Once this initial backup is complete, subsequent backups will only backup files that have been changed, making them a lot faster.Security of Online BackupsThough some may have understandable concerns about a third party holding their most valuable data, in reality online backups are very secure. Before being transferred, the backup data is encrypted to 128-bit level - military grade - making it effectively impossible for any one to intercept or decrypt the data. The user is the only person who can read it. Another common concern is about the security of the data storage center itself. These are invariably class-A facilities equipped with fire suppression, security cameras, personnel access controls, backup electricity generators, using multiple ISPs, high-end firewalls, and clustering and mirroring techniques to ensure the stored data is always available to clients. Except in exceptional cases, the storage premises will be more secure than the client's own premises.X-Drive and Internet Backup Walter Stevens is a contributor at Free-backup.info -- the home of the popular Amazon S3 based online backup service -- Back2zip. This article available at http://free-backup.info/x-drive-and-internet-backup.html What is Internet Backup?Internet backup involves the backing up of your files online. Unlike traditional forms of backup, which require you to have a physical medium on which to store your backup files, such as a floppy disk, CD-R or key drive, internet backup is done completely online. You upload your files to an online server, then can download them again at any time that you desire. It functions as an extra drive on your computer without actually being on your computer, freeing up your computer space and allowing you to backup your files without worrying about diskettes, CDs or removable drives.X-Drive and Internet BackupThe x-drive is an excellent product in the world of internet backup. It serves as an online drive that can be used for storage, backup or the transmission of files. It is similar to having another drive installed on your computer, but you can access it from any computer in the world with an internet connection and requires you to physically move nothing, unlike CD-ROMs or floppy disks. X-drive is found at www.x-drive.com. The drive can hold 5 gigabytes of data. At the current time there is only one size x-drive, but this could change in the future. 5 gigabytes is quite a bit of storage, and can hold a lot of your files. Backup is a very important thing in this computer age. Great damage can be caused by a power surge, system crash or even a computer virus, resulting in the loss of your computer files. Having backups of your files is an excellent way to secure your data and make sure that no matter what harm may befall your computer, you will always have access to your important files. Using a form of internet backup such as the x-drive is a powerful way to backup your files. Physical media such as CD-ROMs or floppy disks can become damaged themselves, and you can find yourself unable to access your data even from your backups. With online storage, you know you will always be able to access your files, and you can move your files wherever you go or whenever you change computers quickly and easily.How do I Get an X-Drive for my Internet Backup?In order to purchase your x-drive, you must go to the internet address of the x-drive found at www.x-drive.com. The drive gives you 5 gigabytes of storage, which is quite a bit of storage, more than you will find on any physical backup medium. It is one of the more powerful tools for internet backup, and is fairly inexpensive costing only 10 dollars a month. For those new to internet backup or the x-drive, they also offer a free 15 day trial so that you might test their system and see if you feel that it works for you. This is an excellent offer, and can greatly assist you in your computing efforts. It is always smart to backup your computer, and the x-drive can make your backup go easier and smoother than you ever imagined.Why Do I Need to Backup My Data? Walter Stevens is a contributor at Free-backup.info -- the home of the popular tool for online backup and recovery -- Back2zip. This article can be found at http://free-backup.info/why-do-i-need-to-backup-my-data.html What is Data Backup?Data backup involves the storing of files from your computer in another location. In this way, if there is ever any loss of data on your primary machine, you still have your data in backup in order to restore those files. In the world of computers loss of data can be devastating, and while there are possibilities for recovery of data after a disaster it is far easier to restore your files from backup than to attempt to find your data on a crashed hard drive.Why do I Want to Backup My Data?Data backup is easy to do and can save you great amounts of time as well as ensure that your data is secure in the case of disaster. Data recovery is a very difficult, time consuming and expensive process, and it is not even assured that you will be able to recover your data from a system crash. Backup does not take much time, as it is easy to put your files onto another medium, and is not too expensive, depending upon what mediums you use to backup your data. There are many different options for data backup, and you will have to choose the one that is best for you.What is the Best Data Backup Option for Me?The traditional floppy disks of a few years ago have become essentially obsolete, and it is not surprising considering the limitations of that medium, and the new technologies that have become available in the meantime, such as CD-Rs, DVD-Rs, online backup and key drives. These are all very powerful tools which can hold far more data than a 3.5 inch floppy could ever dream of holding. One of the most powerful new data backup utilities is the key drive. These key-chain sized drives can hold up to a gigabyte more of data, depending upon the size purchased, and will not scratch or damage as easily as a floppy disk or even a CD-ROM or DVD-ROM. You can purchase a key drive for as little as $20, and it will plug directly into you computer and be able to be immediately be used.CD-R, DVD-R versus CD-RW, DVD-RWCD-Rs, CD-RWs, DVD-Rs and DVD-RWs are also very powerful tools for data backup. CD-Rs and DVD-Rs are very inexpensive, costing less than a dollar a disk oftentimes. However, these devices do have the limitation of only being usable once. Once your CD-R or DVD-R is finalized, it is finished. You can access data from the disk, but you cannot write any more data onto the disk. This is not the case with CD-RW and DVD-RW. CD-RW stands for CompactDisk-ReWritable, and unlike a normal CD-R they can be rewritten any number of times. However it should be pointed out that they are not as manipulable as a traditional floppy disk, where you can save and take off files very easily. Each time you want to rewrite your disk, you must rewrite the entire disk and go through the entire burning process. However, this is still an excellent way to backup your data as a CD-RW or DVD-RW can hold hundreds of thousands of megabytes, respectively. You need to backup your data, and there are many ways that you can do so.Weaknesse in Computer Forensics Andrew Whitehead is a contributor at Free-backup.info -- the home of the popular Amazon S3 based software for online data backup -- Back2zip. This article can be found at http://free-backup.info/weaknesse-in-computer-forensics.html Weaknesses in Computer ForensicsWithin the field of computer forensic science, as in any relatively young discipline, there are weaknesses to be found. In computer forensics the main culprits are training, operational standards, and international standardization.Computer Forensic TrainingThere are many private organizations offering computer forensic seminars and classes. With the growth of computer crime, computer forensic training is a worthwhile investment for any organization - but who should receive it? Computer forensic evidence is very volatile, to preserve it law enforcement personnel should be trained to handle it. Network operators should also be trained, to improve their abilities in intrusion detection, and lawyers should receive some training to give a basic understanding of computer evidence.Operational Standards in Computer ForensicsComputer crime, perhaps more than any other, can be international in scope. There is a need for basic guidelines for the evidence collection process to be established worldwide. This ranges from broad principle that apply to nearly every investigation, through organizational practices so that a minimum standard of planning, performance, monitoring, recording, and reporting is maintained, to recommended procedures, software, and hardware solutions.International Standardization of Computer ForensicsDifferent countries each have their own computer forensic methods, standards, and laws. What is acceptable evidence in one country may not be in another. This is a serious problem when dealing with international crimes, as computer crime often is. The Internet may have no boundaries, but law enforcement does. Investigations that leap from server to server, from country to country, crossing many borders on the way are complicated not only by evidence handling differences, but also by political differences and legal differences. There are some countries in which the networks are owned and controlled by government agencies, who may have little or no reason to cooperate with foreign governments investigating a crime. What is considered to be hacking in the US is not considered to be a crime in other countries, protecting the individual that committed the crime. Fortunately efforts are being made to bring some standardization to procedures regarding digital evidence. The G8 group has recommended six principles for digital evidence gathering:- 1) All standard forensic and procedural principles must be applied. 2) Upon seizing digital evidence, actions taken should not alter the evidence. 3) People accessing the original digital evidence should be trained to do so. 4) All activities relating to the seizure, access, storage, or transfer of digital evidence must be completely documented. 5) Individuals are responsible for all actions taken while the digital evidence is in their possession. 6) Any agency that is responsible for seizing, accessing, storing, or transferring digital evidence is responsible for complying with these principles. This is a start in standardizing computer forensic evidence gathering procedures but there is still a long way to go. Many countries have not adopted these recommendations, and probably will not if they do not have the necessary training resources. The sting in the tail is that these are the countries that pose the greatest computer crime threat.Three Reasons for Online Remote Backup Kalb is a contributor at Free-backup.info -- the home of the popular tool for online backup and recovery -- Back2zip. This article can be found at http://free-backup.info/three-reasons-for-online-remote-backup.html Three Reasons for Online Remote BackupOnline remote backup has risen in popularity the last few years. For a reasonable fee all types of businesses are entrusting their data to travel across the Internet and storage of that data in a remote location. Whether this is because of the rise in terrorist threats or the further developments of encryption and security is debatable. For whatever reason, online remote backup services are popping up all over the technology landscape and for three solid reasons. Online remote backup has advantages over traditional backup solutions, its security features are often better than most in house data security and it can mitigate risks and threats to your critical data.Online Remote Backup AdvantagesBackup and recovery plans can be expensive to invest in. There is the cost of hardware, the cost of the software, and the cost of hiring trained employees to handle the process. In addition there is the time, which equals cost, of performing the backup process. Depending on the amount of data your company warrants as critical to backup and the amount of data you generate on a daily basis the time for backup can be extensive. Online remote backup can reduce this cost dramatically. Through its automated process, its need for little or no additional investments, and the quick and easy availability for data recovery, you should see immediate results in your bottom line.* Online Remote Backup SecurityIn house backup plans can sometimes overlook the obvious need for security. Many do not see the need to secure the backup data when the data is kept inside their own walls. There are statistics that speak to the need to do so. Employees often perpetrate damage, destruction, and loss. Curiosity or revenge can push people to enter an arena they normally would not go into. Data can draw this type of response. Protecting and securing your data has a lot to do with protecting your employees. When one employee has committed a crime, everyone is subject to questioning. It does not make sense to leave the door open and online remote backup can close that door. Online remote backup sends your data encrypted with a key only you hold. The backup process cannot be initiated except through authentication. You will know who requested the backup because you have identified and authorized certain people to do so and a log will tell you who performed the backup. In addition, once the data has arrived to the remote location, You should have the added security any online remote backup service would provide along with trained staff and a 24/7 customer service policy. Can you say the same for the backup data located in your office?Online Remote Backup Mitigates RiskOnline remote backup data is sitting on a server in a far away place. Your connection is the Internet and only through authentication and authority can someone download or retrieve the data. The data is not open to your network, therefore technical disasters cannot affect the data. It stays clean and trouble free until you solve your technical issues, human disasters, or natural disaster. When you see the need to recover safely your data is waiting for you, unharmed and clean from the risks and threats at hand.Typical Data Recovery Scenario! Lison Joseph is a contributor at Free-backup.info -- the home of the popular Amazon S3 based software for online data backup -- Back2zip. This article can be found at http://free-backup.info/typical-data-recovery-scenario.html Why would I ever want Data Recovery!Data recovery can be your headache when it is the last thing you want. A typical scenario leading to you scrambling around for data recovery experts could be something like this: One fine morning, you start your system to work on your tax worksheet. You are adding the data about the current month's tax returns on your database of tax payment. Out of the blue, there is a power failure, when you least expected it. In fact, you were almost done with the data entry part when the power blacked out. Now after an anxious wait for the power to come back, you switch on the system only to be informed by the operating system that a certain part of your hard disk has become inaccessible. So not only is your current month's tax data lost, but the whole tax database has become inaccessible.So how to go about data recoveryOk, so data recovery can be your share of worry any time of the year! So how do you go about it? What do you need to do? Do you recover the Data? Questions start crowding your agitated brain. Here are a few simple things you can do. Immediately stop using the problem hard disk as any further use of the disk can jeopardize data recovery. Don't even try to run the basic scan disk or disk check to see if you can fix the corrupted part of the hard disk. Look up a simple Data Recovery software from the internet. Several of them are available and some of the are even free to try. If you are comfortable working with it then try and let the software scan your hard disk to evaluate whether data recovery is possible and if possible how much of it can be recovered. If you think you can safely recover the data you want from the problem hard disk, then try doing it without further disturbing the files on the disk. If you think, it is beyond you, or if you think data recovery is an expert's job, then look up a data recovery expert from the yellow pages or with assistance from your hardware supplier.What to expect from Data Recovery ExpertsWell, so finally you managed to get hold of a supposedly good data recovery expert. Now the question is can you blindly trust your data recovery expert to wave his magic wand and come up with all the lost data like a magician produces rabbit from his hat! Well, to be frank, you are best advised to take the data recovery expert's claims with a large pinch of salt. How much data can be retrieved and the accuracy of recovered data depends on how much writing/over-writing activity has happened on your hard drive after the data loss. Another important factor is the nature of the damage that has happened. If all the relevant factors are favorable, then you can safely expect your data recovery expert to come up with your entire tax database intact! Good Luck!Wonderful Ways to Have a Handy Backup of Your Files James Fohl is a contributor at Free-backup.info -- the home of the best online backup software -- Back2zip. This article can be found at http://free-backup.info/wonderful-ways-to-have-a-handy-backup-of-your-files.html Wonderful Ways to Have a Handy Backup of Your FilesDo you always want to carry a handy backup copy of your website, photos or music collection? Let's face it, some users want to have the ability to have a backup copy of their files so that they can show their friends their latest photos wherever they maybe. Whether it's at an internet cafe or the local library, a lot of people wishing they had their files don't because carrying around a large CD-R just isn't very handy. Luckily, the recent years have lead to an explosion in handy little ways to allow you to always be able to carry a backup of your files. First off are the little flash memory sticks that are being produced by literally every computer company on the face of the earth. Most are smaller than a pack of Wrigley's chewing gum, but have the ability to store tons of data. Talk about handy!Handy flash memory based keychains starting at around fifteen dollars are perfect storage mediums for backup files.Starting at around fifteen dollars, a user can go out and buy a 128 megabyte memory keychain. Plug it into your computer's USB port and boom; easy access to your files. Since the memory keychains utilize the USB port for their power, users do not need to worry about carrying a power pack, or replacing batteries. The small flash memory units are extremely handy because you can literally take your backup files anywhere you go. If you are saying to yourself that 128 megabytes is simply not enough for your backup file, then continue to read on.The handy size of the keychains allow users access to gigabytes of space for their backup files.In under the size of a pack of gum, flash memory keychains exist that have the ability to store gigabytes of data. Not just megabytes, but gigabytes. Although one gigabyte units start at fifty dollars, they are extremely handy when compared with large CD-R discs.Business card sized CD-Rs are another handy media for transporting backups of your files.If you are against the whole flash media brigade for whatever reason, and wish to stay with good old CD-Rs, then business card CD-Rs are for you. Business card CD-Rs are handy little CDs that are kept in a small protective case the size of a business card. While they can easily be stored in a wallet, they have a limit of around fifty megabytes for your backup files. Also, users utilizing the handy sized CD-R discs for their backup needs should also be very cautious about using the media in their CD drives. A lot of CD burners, as well as normal CD-ROM units do not support the disc. Always check the manual of your CD-ROM drive to see if it supports business card sized CDs, otherwise you may loose your disc in the unit. While business card CD-Rs ultimately look cool, they just aren't as handy as flash based memory keychains. While the keychains are more expensive, they are more durable, have much more space for your backup needs, and are supported in a lot more computer systems than the card CD-R counterparts.Update and Refine the Disaster Recovery Plan Lison Joseph is a contributor at Free-backup.info -- the home of the popular Amazon S3 based online backup solution -- Back2zip. This article is also at http://free-backup.info/update-and-refine-the-disaster-recovery-plan.html Disaster Recovery, a race against time!Data keeps changing with passing time, which makes keeping pace with the changing data one of the most important challenges before data security/disaster recovery officials. In the case of any enterprise, logical environment is something that is in a state of constant flux, being changed and redefined with the passage of every hour depending on the various requirements of time. One of the important aspects of any disaster recovery plan is a sensible backup plan for making redundant copies of all critical files of the company database. Apart from making constantly updated backups, the disaster recovery plan should also take into account all the critical changes in the logical environment as it might be of supreme importance at the hour of reconstruction after a tragic disaster and data loss.Backups can become obsolete, making disaster recovery impossibleThe fact that logical environment composed of various bits and pieces of data are ever changing means that there is all the possibility of backup becoming obsolete unless extreme care is taken. This problem of obsolete backup marring the prospects of successful disaster recovery can be avoided only if there is a real time backup. This calls for the right installation of right infrastructure in place, which everybody can afford to, especially small business houses that is willing to set aside only meager sums for data security budget! Take for example the common scenario of new software being installed at the instance of a particular department in the enterprise for a specific purpose. It could be new accounting software or new human resource management software. With the installation of such a new software the logical environment undergoes a critical transformation and the backup plan may need to be updated and refined to take into account the new development. Only such a refined and updated backup that accounts for the changes in the logical environment will be useful in a picture perfect disaster recovery.Not just the backup but also the entire disaster recovery plan needs refining and updatingLike in the instance of backups, the change in logical environment as well as other relevant factors, the disaster recovery plan needs to be constantly updated and refined to be of any constructive use during crises. More often than not, what happens is that once bare bones disaster recovery plan is in place, those concerned with it tend to push it to the freezer and get on with things of "greater importance"! But know this now, and without any delay that a workable and up-to-date disaster recovery plan is as important as any other work in a logical environment consisting of large amounts of critical data. Considering the mere existence of a disaster recovery plan to be enough can prove to be a costly mistake in the event of a disaster. Even a seemingly successful disaster recovery may not be able to reconstruct the logical environment as it was before the disaster struck, unless the disaster recovery plan was reviewed frequently to incorporate necessary changes.Undelete Software for Your Business Walter Stevens is a contributor at Free-backup.info -- the home of the best online backup software -- Back2zip. This article can be found at http://free-backup.info/undelete-software-for-your-business.html What is Undelete?Undelete is any software utility which allows you to essentially undelete or recover deleted files from your computer. This is the most basic form of data recovery, as it allows you to recover files that you thought that you had lost from your computer. If you work with Windows or other similar operating systems, you most likely already have a basic form of undelete on your machine. The recycle bin is a program which allows you to recover files that you have deleted. When you delete a file, it is first sent to the recycle bin, where you can then permanently delete it manually or wait until the recycle bin cycles itself and deletes the files for you.Why do I Need Undelete for my Business?Undelete is a very important utility for any business. In this computer age, data can be as precious as gold and if you need access to a file that has been deleted for any reason, you will want to have your hands on a powerful undelete utility that will allow you to recover your files. Data can be lost for any number of reasons: accidents, viruses, system crashes, etc. Anything that causes a loss of vital data can be harmful to your business, and you will need to be able to restore it if the case requires it.How do I Get an Undelete Program?There are many different undelete programs in existence, made by many different companies. There are two basic forms of undelete software. One, like the recycle bin of Windows operating systems, must be installed prior to the deletion of a file. Executive Software makes an excellent undelete program of this variety. They replace your recycle bin with what they call a recovery bin. Unlike the recycle bin, every single file that is deleted from your computer will be placed into the recovery bin, from which you can undelete it if necessary. It is a very powerful tool, and one which could greatly help your business. Other undelete tools may be installed after the event of deletion. When you delete files, even if you cannot necessarily see it, it is oftentimes still within your system somewhere. These undelete programs will search out the likely places that your file is, and if they can find it will restore it to your computer so that you can access them and manipulate them as normal. There are many different sources of undelete software. You can try the web site of Executive Software, found at www.execsoft.com. You can also try www.active-undelete.com, which is another powerful undelete tool. If these do not suit you, however, another excellent source is www.download.com. They will have information on a number of different undelete utilities, as well as trial downloads and even freeware versions of undelete programs. This will allow you to get a free undelete program or try an undelete program before making the monetary investment to purchase it for your business.Using the Undelete Command in Windows 98/95, DOS James Fohl is a contributor at Free-backup.info -- the home of the popular Amazon S3 based software for online data backup -- Back2zip. This article can be found at http://free-backup.info/using-the-undelete-command-in-windows-98-95-dos.html Using the Undelete Command in Windows 98/95, DOSEarly Windows users, as well as DOS users have a really great undelete tool built in to their systems. A lot of computer users are still running Windows 98, or below. While Windows XP has been on the market for more than three years now, some people have been hard pressed to make the upgrade, while others have found themselves completely happy with their Windows 98 setup.Undelete is not available on Windows XP systems; only DOS and Windows 95-ME.A really cool program that was in previous versions of Windows, as well as certain versions of MS-DOS is not available in Windows XP. The tool, Undelete is a DOS command prompt program that allows users to literally undelete the files that they had previously deleted. The major limitation of the software is the fact that is can only recover files if no new files or changes have been made. So, basically the undelete command will allow you to recover files if you accidentally delete them, but it will not be able to recover files that you deleted a week ago.Users should be experienced, as the undelete utility does not have a graphical user interface, and relies on text commands.Undelete isn't a flashy program. There are no graphics, and the program is not very user friendly. To start the program, you'll need to activate a DOS prompt in your Windows operating system. To do this, click the start button and select "Run". Type in "command" and press enter. A black box with white text will soon be visible. This is the DOS prompt, and you will soon be able to use 'Undelete' to undelete your files. In order to use Undelete properly, you will have to learn the options for the program. As mentioned before, Undelete is a text based program, and does not have any spectacular user interface.Undelete offers the user several different options to help recover your deleted files.To gain access to the commands of Undelete, type in "Undelete /? " at the DOS prompt, and press the enter key. The following text will be displayed on your screen; /all - Automatically recovers all of the files you specify. /list - All available files are listed (but files are not recovered). /DOS Restricts recovery to those files that meet the file specifications (filespec) in the disk directory table. /DT - Restricts recovery to those files found in the Delete Tracking File. /DS - Restricts recovery to those files found in the SENTRY directory. /load - Loads the Undelete memory-resident program into memory using information defined in the UNDELETE.INI file. /unload - Unloads the memory-resident portion of the Undelete program from memory, turning off the capability to restore deleted files. /purged[d] - Deletes the contents of the SENTRY directory. /status - Displays the type of delete protection in effect for each drive. /S[d] - Enables the Delete Sentry level of protection and loads the memory-resident portion of the UNDELETE program. /Tdrive[-entries] - Enables the Delete Tracker level of protection and loads the memory-resident portion of the UNDELETE program. The optional entries parameter specifies the maximum number of entries in the deletion-tracking file (PCTRACKR.DEL). It must be a value in the range 1 through 999 with the default value determined by the type of disk being tracked. After you have read through 'Undelete' program options, you will need to goto the specific directory of where you wish to undelete the files. Below is an example; C:\> cd Downloads <- cd "change directory" C:\Downloads\> Once you are in the appropriate directory, rerun the 'Undelete' program, only this time fill in the correct options. For example, if you wanted to restore all files in the directory, you would use the '/all' command. Below is an example; C:\Downloads> undelete /all The above command will allow the undelete software to safely recover your deleted files. Now that you have an understanding of how the undelete software works on your operating system, the next time you find yourself worried about deleted files you can simply remember what you learned about the undelete command. |
