Hi,
We are using Budtool 4.6.1a to backup an F760 and an F630 to a Breece Hill Q2.15 jukebox with 2 DLT7000 drives. We backup each qtree as a separate request in budtool. We started getting poor performance on the smaller qtrees, and started using the hidden ndmpd logical_find command described in Bug 12424. We recently upgraded to 5.3.5P2, and I found that this option is causing ndmp connection problems between Budtool and the filer. As a result, I have backed off to 5.3.5, where this option works without a problem.
My question:
How best to backup a 330GB volume with many small qtrees? Should we just backup the entire volume as one request, or continue to backup each qtree individually? Are there any problems with backing up the entire volume at once? This will allow me to dump (no pun intended) the problematic ndmpd logical_find option, as well improve general dump performance.
Thanks,
Moshe
