The frequency with which backups should be made depends on the amount of stor-
age space on a hard-disk drive and the volatility of the data contained on the drive.
Heavily used systems require more frequent backups than systems in which files are
seldom changed.

Dell recommends that you back up the hard-disk drive at least once a week, with a
daily backup of those files known to have been changed. Following these guidelines
ensures the loss of no more than a day’s work in the event of a hard-disk drive failure
or if you inadvertently delete one or more important files.

As further insurance against data losses, you should keep duplicate copies of the
weekly and monthly backups at an off-site location. Doing this ensures that you lose
no more than a week’s work, even if one of the on-site backups becomes corrupted.

Iomega Zip drives are fast, convenient, and reliable devices that can back up data at
rates of up to 11.2 megabytes per second (MB/sec) (sustained, without data compres-
sion) and can often run unattended. Dell offers Zip drives with storage capacities of
100 megabytes per Zip disk and recommends these drives and their associated
backup software for use as system backup devices.
