The times listed are HH:MM as you suspected. And why does it take so long?
Well, the dbbackup was a normal-while-everything-else-is-running backup,
maybe this is a partial excuse.
The restore, however, was the only thing running on the

I was told by a Tivoli Engineer at one time that you shouldn't let them
grow much over 50 gb. Primarily, because of the reason you state here

I have 2 rules for DB size.
1. Restore time - if it will take longer than your recovery window on your
TSM server to restore the database, your DB is too big. A good estimate of
restore time is 50% longer than the backup - 2 hours to backup the
database, 3 hours to restore. If your maximum
