Hey guys,
My company has about 25 servers, some of them local in the office some
remote far far away.
I was reading back and fourth backup strategies and still a little
frustrated.
Bascally my problem is following:
- the backups will be made to RAID array (1 TB) and to the Tape (24 Gb)
- some server should be backed up to Raid some to tapes
- i'm plannig on having atleast 3 weeks cycle.
My confusion is... will it be better off making separate POOLS for each
server, and inside them FULL and incemental Volumes? or do a only two
pools (one for raid one for tape drive) ?
Pools are most useful in managing retention times. So, how you apply
them depends a lot on what sort of backups you make - I, for example,
have a Full pool, for full backups obviously, and I keep the volumes for
a year. Diff pool (weekly differentials) are kept four months, Incr pool
(daily incr.) are kept 10 days. This allows access to a staged number of
backups, but requires access to up to 8 jobs volumes for a restore.
How you set up your pools depends on your needs. If you want some more
detailed suggestions you have to give us more input on your planned
backup scheme.
Will it change speed of the data access in case i need to restore a
single file?
Probably, especially in case you need to manually mount the needed
volume. Apart from that, I guess in such a case the building of the
directory tree from the catalog might be the longest part of a restore,
and you can't influence that with the pools setup.
or i am missing the hole conept behind pool/volumes?
Not necessarily :-)
A pool is just a collection of volumes with some common default setup,
that's all.

Thanks,
Sincerely,
Kiryl.
