Backup Exec Speed

[David_Knight]

I am having issues with the speed of the backup. I maybe way of mark here, however it seems that after I run a sql back at approx 1000mb/min and then try and run a normal backup the rate decreases to approx 13mb sec.

any ideas?

13 MB/sec are approximately 700 MB/min, which is a good rate for files. Usually SQL backups are faster than files backups.

sorry when i said 13mb sec I meant 13mb a minute.

apologies.

Is your tape backup attached to a dedicated scsi card or is it sharing a raid adapter?

[David_Knight]

connected to its own scsi card.

When the sql bakup runs I get speeds of 1000MB min. When a normal backup runs I normally get 80 mb a minute. However on occasions the above happens and this is sometimes after a sql backup has run.

Are you fully patched

[David_Sanz]

That's really slow, indeed.

Are backing up a file system with lots of very small files?

That may be the cause.

We actually have a very similar issue being the throughput is so slow. We disabled our antivirus software (Norton) realtime scanner not to scan backup files, and it seems to me it speed it up a bit. The next thing we are still working on is to defrag the disk, actually happening now and see if it makes any difference.

But at the end of the day, yes we do have a lot of small files to back up and this is reality. Are there any other options available to accomodate (speedup) this sort of environment, being a lot of small files ???

You could try using livestate to get all your files from various locations into one location then backup that single location.

I maybe wrong on this but people receiving slow MB per min backup try stopping and stopping the services(which seems to work when I have done a sql backup and then try a normal babckup) if that fails reboot the backup exec server. Works everytime for me.
