Bobby,

We get 12MB/sec(350GB) from our Windows Notes netbackup client to our DSSU on our Solaris Master/Media Server.

This is what we have done to increase performance to 12MB/Sec

1.) Set Lotus Domino scheduled tasks to happen outside of the backup window
2.) Made sure we have the latest nic and storage drivers.

3.) Both of these take time. Format is probably the best way to clean things up.
        a) Run a defrag when Domino offline
        b) Backed up lotus domino (offline) using the plain netbackup agent(Not the Domino agent), reformat the data drive and restored from tape. We get 30MB/Sec with an offline backup.

We are planing on setting up an Lotus archive server. Which should decrease the backup volume on our notes mail server. The backup policy of the archive server has yet to be determined but it will most likely be a monthly archive and then backup. Our notes mail server would continue to backup with daily fulls.

I hope this points you in the right direction.

Karl
