I have an ADSM performance question. It takes more than 11 hours for ADSM
to backup one of our big NT file/printer server. There are about 4 millions
objects on this server. One filespace has 60 GB data and it takes 2 hours to
backup. The another filespace has 125 GB data and it takes 9 hours to
backup. Everyday normally only 2-3 GB data are transferred and backed up.
Look like the most of time are spent on file comparing. I'd like to know if
it is normal for ADSM backup. I also have a local DLT tape drive running
incremental backup using BackupExec. It only takes 3 hours. The following
is a summary of performance data. ADSM server version is 3.1.2.40 and
client is 3.1.0.7.
