[ADSM-L] Antwort: [ADSM-L] Data Protection for Lotus Domino

Hi,

just use the "SESSIONS" parameter in domdsm.cfg
in my experience it behaves like this:
the number used, is the number of databases wich are backed up in a bunch.
after completion of the last db it take the next block..

maybe also have a look at the following:

Hi all! We are currently migrating part of our company from Netbackup to TSM. They currently backup their Lotus Domino servers to tape (through the SAN) by using Netbackup for Lotus Notes and they achieve an average throughput around 10 Mb/sec. This performance is acceptable for the customer. It's achieved because Netbackup is able to use multiple backup streams. We installed Data Protection for Lotus Domino and we see an average throughput of less than 1 Mb/sec. Tracing showed that the client is mostly waiting for the Domino server. My guess is that we can achieve 10 Mb/sec too if we were able to use some kind of parallelism with TDP, but I cannot find a way to do this, other than backing up each database individually at the same time... Not very convenient. Does anybody have some tips to boost TDP performance in some way? Thank you very much for any help in advance!
