It is not enough to store your software and data files on your computer and assume they will always be there when you need
them. Why? Well, computers can break down, hard drive surfaces can scratch, and your data can be
compromised. You might delete your files by mistake, or a computer
virus might corrupt your files! At the least, it can be a hassle to hire someone to professionally retrieve your
data. But in the worst-case scenario, your data can be lost forever, causing you large losses of time and money.
Data backup is the process of making a second copy of computer data and software so that it is available if the original
copy is damaged or lost. It is important to periodically backup the contents of your computer's hard disk onto
removable media, which are available in the form of tape cartridges, disk cartridges, and flash memory devices.
Store these data backup media in a safe place, even off-site if your data is mission-critical. With the availability
of high-speed Internet access, it is also possible to upload or archive data from your computer to a web-based server,
where it is available for download or data restoration purposes. This may be an acceptable backup solution for some
applications. Backup.com, Carbonite.com, IBackup.com, IDrive.com, and Mozy.com are just a few of the vendors who
provide online data backup services via the Internet.
When designing a backup procedure, be sure that it is convenient and requires minimal human interaction. Plan a
backup schedule and a backup media retention scheme that fits your organizational or personal requirements. In
deciding what type of media to use, consider whether the media and the ability to read your backup data will still be
available in five or ten years!
