Re: [Networker] Backup Pools
2006-09-21 14:53:34
Well first we have a IBM LTO 3581 jukebox and a IBM LTO 3580 single
drive. We 1000 mbps throughput. But the backup server only has a
100mbps card. There are 17 clients. At full backups 5 clients are at
least 100gb - 200gb per client. And the others are between 30 and 60
gb. 5 groups are single client and are the larger clients, 1 is double
client median in size and 1 group has 9 clients which are smaller save
sets. 15 clients are using the jukebox and 2 are using the single
drive. We have another single drive but that is used by a different
department but would be accessible to us in a disaster recovery
operation if need be which is why I was looking into breaking up are
most important server into different pools as to aid in a quicker
recovery. If more than one server was to crash we could recover 3
servers simultaneously if we know for sure that the servers are on
different tapes.
Thanks for the help

Thanks for the reply. So if I have a jukebox with 7 slots and say I
have 4 different pools with 1 to 2 tapes for each pool you think
there would be long waits between backups? Shouldn't it be only the
wait of the jukebox changing the tape? Right now all session have to
wait for the previous one to finish per tape drive so wouldn't that
be the same either way? Right now I have 15 clients being backed up
nightly to one tape drive using one pool. I am trying to get it so I
can specify certain tapes for certain clients. I'm guessing the only
way to do that is through pools. Is there other ways?
Possibly. Its difficult to say without knowing how much data would go
to the individual devices and how fast the throughput is. Answering
your question would be easier if you explained what your hardware and
network environment is like and the amounts of data involved.
