Re: [Veritas-bu] LotusNotes backup strategy
2007-10-16 10:30:13
We have several Domino servers and have been able
to utilise point in time restores.
Our win2k3 mail server backs up 350GB at 10-12MB/sec
using the notes agent. Doing an off-line backup we are able to do 25-30MB/Sec
We are hoping to move our mail server in the new year
back to Solaris. We hopefully should see 25-30MB/sec backup times.
We still do nightly FULLS and have touched lightly
on daily notes transaction only backups. They seem to work fine.
Our notes admin will be implementing a notes archive
server before year end. The hope is that our daily mail backup volume will
decrease and that we can move data to the archive server on a quarterly
basis. The archive server will be backed up quarterly while the email server
will be backed up daily. I don't think we will be using veritas Vault.
