I've been using amanda for awhile now, loving it. I have 5 hosts being
backed up, 4 of which are < 18G on L0's and one of which has a 180GB
RAID partition. I have a 15 tape changer with AIT2 tapes.
The problem is obviously that amanda can't span filesystems, and my
usage on the RAID has now exceeded the size of the tapes. As I see it I
have two basic options:
1. run two seperate config's, one for the clients, and one for the RAID.
This strikes me as bad for two reasons. First it doesn't scale once the
RAID itself is too large for a tape (right now it's about 70Gig, with
that plus the L1's of the clients is too big for tape). The other
problem is that I burn two tapes a day, only one of which is really used.
2. use GNUtar and excludes with maybe three mountpoints on the RAID,
bkup1 bkup2 and bkup3. Then, ideally, I would somehow force L0's on
alternating patterns so that no L0 of bkup1 ran the same day as 2 or 3.
I think this is the way to go, as the L1/L2's of this filesystem are
pretty small, but the L0's are ... well.. .huge.
My questions:
Is that a fair summary of my options (as well as #3, buy someone else's
backup software, which isn't an option)? If so, is there a way to
achieve the alternating L0's in option 2 without running amadmin _daily_
? If not, what other options exist, short of hiring some programmers to
write the "span filesystems" mod for amanda?
Thanks!
