Need to restore different versions of files (for example, file systems 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
level lower. However, with this schedule you should use different tapes each day because a file 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.

Are backing up 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.
