I've got a server farm of about 30 machines, most on various RedHat
distributions, a few AIX.
I have 3 tape drives, an 8, a 24 and a 40Gig, all HP DAT tapes.
I have 10 physical backup tapes available for each drive.
The tape drives are attached to 3 linux computers, Columbia, Frith & Coffee,
respectively, which have Amanda 2.4.1p1 servers. All the clients are
running either 2.4.1p1 or 2.4.2p2 .
I have created a configuration directory for each server in /var/lib/amanda
and a disklist which has the clients and partitions for each item to
be backed up by the respective server.
When I analyze the existing space used by the clients, I find that
each server is subscribed for between 100 and 180% of the capacity of
an individual tape.
Questions:
- is this a sane configuration?
- is this a better configuration than throwing 3 tape drives on 1 amanda server?
- is this a better configuration than just using 1 tape drive on 1 amanda server
(the 40, obviously) and using more tapes?
- what would you recommend for the way to ease into backing up this lot?
i.e. uncomment 1/2 of the disklist descriptions the first night, 1/2 the
second, or 1/4 the first, for 4 days... or ???
