To restore different versions
of files (for example, file systems that are used for word processing)

This schedule
saves all files modified that day, as well as those files still on disk that
were modified since the last backup of a lower level. However, with this schedule,
you should use a different tape each day because a file that changed on Tuesday,
and again on Thursday, goes onto Friday's lower-level backup looking like
it did Thursday night—not Tuesday night. If a user needs the Tuesday
version, you cannot restore it unless you have a Tuesday backup tape (or a
Wednesday backup tape). Similarly, a file that is present on Tuesday and Wednesday,
but removed on Thursday, does not appear on the Friday lower-level backup.

To backup a number of file systems
on the same server
|
Consider
offsetting the schedule for different file systems.

This way you're not doing all level 0 backups on the same
day.
