Subject
TDP for Mail (Domino) throughput






Is this as good as it can get for backing up Notes.  or is 6MB/s just as
good as it gets.

If anyone has any ideas, I'm all ears.  I've been looking at this all day
with the AIX sys admin,
And the Notes admin, and we can't seem to make any headway.  We're pushing
11 hours to back up this
Notes server, and that's getting right at the window.

Snippet from last log

Total Domino databases inspected:         3,035

Specifics on the Notes server and TSM server

We are backing up 2 Notes servers that are running on AIX.
Each Notes server is 250GB.

Each Notes server is taking 10+ hrs. to back up.  We are using TDP for
Mail to backup the Notes servers.
The mailboxes are on a jfs2 filesystem (ESS F800 SAN device).
The Notes servers are backing up over the network via Gb ethernet.

TSM server is TSM on AIX 5.3.5.1  /  9 LTO1 drives / 3 LTO3 drives / Gb
eithernet for LAN (Backups run on LAN)

We set the statistics on for TDP on the client side and captured
statistics.  Here is what that yeilded.
