The Domino TDP does not honor/use the resourceutilzation settings. There is 
very little you can do to improve the Domino TDP
performance. I have gone through this, over and over.  A lot of the speed issue 
is the Domino server itself.

For instance, when we start the backup process on one of our 4,000 user 
servers, it can take 30+ minutes from the time the process
starts and queries the Domino server what needs to be backed up and any actual 
backup traffic starts to flow.

Even if you divided the backup into multiple nodes and configured the domdsmc 
process to only backup certain mailboxes, if you run
10-of these, there are 10-queries going against the same Domino server.

Re: [ADSM-L] TDP for Mail (Domino) throughput - Multiple mount question






Hello,
      I am right now testing LANFREE on NT machine using TDP-Domino. I am 
getting about 35 MB/Sec. We are using LTO-3 drives.

06/07/07   12:20:22      ANE4991I (Session: 313196, Node:
Z-SPAREDL585-1-DOMINO)
                          TDP Domino ACD5209 Data Protection for Domino:
Selective
                          database backup from server NOTES003 complete.
Total
                          Domino databases backed up: 175  Total bytes
transferred:
                          58605536768  Elapsed processing time: 1526.13 Secs
                          Throughput rate: 37501.27 Kb/Sec(SESSION:
313196)

      Does any one have any idea, how can I backup in multiple tapes?.

Note: I have "resourceutilization 4" in dsm.opt and maximum mount as 4 for the 
node. But still TDP for domino mounts only one tape
on the drive. There are two drives shared between Node and TSM server and they 
are free when I start the backup

Thanks & Regards

James,

  Different environment but same issue,Getting around 28Mb/sec with LAN free.
Whether anybody getting more than that in LAN free environment?

  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.

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.
