I am using exchange server 5.5 with SP 3. The exchange server backup(ntbackup) usually takes about 1.5 hours but on some days it gets over within 27 minutes and the log shows no errors. I hope someone can explain the reasons

Thanks in advance
 
are you doing full backups every day, or incrementals and differentials as well?
 
then it could depend on other factors...server load (available memory and/or cpu), network load (if your backup media isn't local)...have you checked the files or ever tried to do a restore to an offline server?
 
Not too sure of the scale of the operation, but well worth considering a third-party agent-based solution such as Vertias or Arcserve.
 
I agree with Bronto -- if your server is not busy one day .. the logfiles are not as extensive and far fewer ... each logfile (by default) is 5 megs in size... the less changes that are made .. the fewer logs you have.

If you have a particularly busy day -- such as .. you have added mailboxes, distribution lists, deleted mailboxes .. changed permissions to a container, added a custom recipient, added a delegate to a mailbox or one of its containers.. anything like that will generate an entry in the logs... - then your backups will take longer..
