I was looking into using the dump command to perform the daily backups on
our system. I would like to use one tape a week doing a full backup on
Monday and incrementals the other days. I was looking into using a dump
level of 0 on Monday, 1 on Tuesday, etc. Is this an OK strategy? What
if I miss a day of incremental backups (the tape has been ejected or
something)? Does that cause things get messed up?
As I understand the dump level concept, for a given level n, all files
that are older than the last n-1 level backup are backed up. Is this
correct? If so, let's say I miss my level 3 backup on the first week.
Then on week 2 my level 4 backup will be looking for files modified since
the last level 3 backup, but that was a week ago. So I get a whole bunch
of files backed up that have already been backed up by previous levels.
Right? Am I way off? Please shed some light if you can!
Thanks...
Brad
