Scheduling Backups 

Your backup schedule should cause the least inconvenience to your
computer users:

   *   Backups should be done when no one is using the computer.

   *   Full backups, which take more time and more tapes than partial
       backups, should be carefully planned.

Scheduling the backup for the end of the work day is usually best.  It's
also a good idea to plan the backup for the same time every day.  This
way, everyone knows what to expect and can plan their own schedules
accordingly.



Performing a partial backup the day after a full backup requires less
time (and fewer tapes) than the partial backup almost a week later.  As
the week progresses, computer users modify and add more files since the
last full backup, so more new information exists to backup.

If you schedule full backups for Fridays, you may only need one tape and
a little bit of time for your first partial backup on Monday.  But, by
Thursday, the day before the full backup, plan on using several tapes and
spending a lot more time backing up the computer.

If you perform a full backup daily, the time it takes and the number of
tapes needed remain more predictable.
