back up times are loonnnnng !!

Hi,

Anyone know how to speed up a backup running locally on a 4.0 NT server running 7.3 rev 2575? It took 33 hours and 34 mins to back up 13 gig with verification. Anyway to speed that up ? It's a Seagate Scorpion DAT 4/8 gig.

Also on a different job, with the tapes still being DGD120P with a cap. of 4 gig, why would it prompt me for a second tape after only 2.3 gig?

The second thing first.
Most vendors are a little optimistic about how much they can compress data in an NT env. and I would expect that what you have is a 2/4 GB drive. If what you are backking up is some NT compressed directories 2, GB sounds ok.

The time to backup data depends a lot on hardware, software and the files you back up.
If what you have is 13 files of 1 GB each this is slow, but if you have 1.000.000 small files it could be that there is not very much to do about it.

We have tapedrives that start og stop very fast and that helps a little, but it is slow to backup a lot of small files.

You could turn of verification, but I wouldn't do that on DAT. Or to be correct I would not use DAT for backup and restore. You can't trust DAT for restores.

Dave_c_99,
Are you running the Tape drive on it's own SCSI card or a card sharing with Drives? I had a speed issue and put the Tape drive on it's own SCSI card and almost halved the backup time.
