backup

Personal computer users can consider both local backup and Internet backup.

Local Backup

• Backing up critical files to diskettes. This approach is commonly used by people who keep their checkbooks and personal finance data on the computer. Programs like Quicken and Managing Your Money always remind users when they quit the program to backup their data. If your hard disk crashes, you'll be able to reconstruct your checkbook balances. If you have other files (for example, chapters of a book you're working on), you'll want to backup every single day's work. Copying it to a diskette is quick and economical.
• Backing up to a Zip drive, Jaz, Syquest, or similar hard disks. Once a week or so, you should back up your files (at least your own data files and perhaps the entire contents of your hard drive) to an alternative storage device, such as a Zip drive. These devices hold at least one million bytes on a special hard disk. Backing up usually takes a while (about 45 minutes for the contents of a 500 megabyte hard disk).
• There are also easily removable drives that you can back up to, especially if you have other reasons to use these (for example, for large graphic images that you store offline).

Internet Backup

• Atrieva provides the user with a client program that allows the user to send files being backed up to an Atrieva-designated backup site. One monthly charge entitles you to back up up to 25 megabytes.
• BackupNet sells both a server and a client and is aimed at helping you set up your own intranet.
• QuickBackup is a client program from McAfee Associates. They have a modest charge for the client and a relatively low monthly charge for storing 30 MB. QuickBackup lets you save by folder or file types.
