Hello Amanda People,
I'm running amanda with a five-tape DLT changer, and everything seems to
work just beautifully so far (well, after I spent two hours trying to
label a cleaning tape at least ;). However, I do have some questions
regarding how to use the tapes, or how to arrange them in "tape sets".
What I want to achieve:
If the room with the servers *and* the streamer burns down, I want to
know that I have a full backup (minus the up-to five tapes of incremental
backup that will be lost when the streamer is lost) off site.
I want daily incremental backups, and weekly full backups. A full backup
can usually be done on one tape. And there are seven days in a week here :)
Currently I'm experimenting with a tape-cycle of 15 tapes. Usually only
one tape is used per day, meaning I will have two full dumps during the
tape cycle.
But I'm uncomfortable with having just one series of tapes knowing that
"somewhere" in this series I have two full dumps. If I want to move a
full dump off-site, which tapes do I take? Sure I could look in the
Amanda reports, but I think it's easier to have TapeSet-{1...8}-A and
TapeSet-{1...8}-B tapes, eg. two separate series of tapes on which I am
absolutely certain that I have a full dump on each set.
But this can't easily be done as far as I can see: If I want to run
differently labeled tapes, it's two different configurations. And I can't
label two tapes with the same name without some hackery.
What is the "right" solution?
Thank you,
