Why does this worry you? As long as you know that every disk will
get at least one full dump per dumpcycle, what difference does it
make if they're not all on the same tape?
Indeed. It may look strange at first sight, but even in reality this
works out fine very well.
I have five disks per server, 15 in all. I would like to be able to
pick up a tape and say "this is a tape with a full dump on it" or
even "this is a tape with a few full dumps on it".
Well, that's easy! With 15 disks, it's pretty much guaranteed that
amanda will put at least one full dump on each and every tape, so you
can pick up _any_ of your tapes and say, "This is a tape with a few
full dumps on it."
:- :-) :-)
a bit of a management nightmare.
Not at all.
First there is as Dave said the indexes. But even without indexes
you still have your "amadmin Config info" to find out which tape is
which. And if that disk is crashed too, you still have the paper
postscript labels that amanda prints for you that fit nicely in the
tape box.
I have needs similar to what Michael is looking, and agree with his
requirements. For networks where there
is a full-time backup admin, letting Amanda spread out the level 0's
seems simpler. Restoration is what the admin
does most often, and (s)he should have mastered it.
But for networks where restoring occurs once in a while, tape management
is a tedious task. I'm just an intern,
and the company's plan is to have a set-up that is easy that "anyone"
can do. Having all level 0's on one day,
and incrementals on others seems most appropriate (at least for the
company, :( interns are not expected to stay
with the company for long periods).
The 'strategy nofull' will "always" do level 1's backup. But since our
data change is < 1 GB per day. It's not
a big deal. Moreover, incrementals are kept on disk. Only weekly full
backups are kept on tape.
