Slow Windows Fileserver Backup versus Novell

We've got a backup server running Server 2003 SP2 and BackupExec v12.5 rev 2213. It's been merrily backing up some old Novell fileservers at around 1000 MB/min or more - up to nearly 2000 MB/min.

We've been migrating data off these fileservers to Server 2008 R2 but these are backing up much slower - often less than half the speed - eg 300 to 500 MB/min. One fileserver has a fibre channel SAN and another is virtualised and has iSCSI SAN storage but there's no significant backup speed difference between them. Both are slow compared to the old Novell servers.

A second backup server running Server 2008 R2 SP1 and BackupExec 2012 v14.0 rev 1798 is backing up a Server 2003 fileserver at about 500 MB/min as well.

Does anyone have any experience of this sort of thing or any suggestions as to how we could look into it? Thanks.

Looking into this, thanks. So far it looks promising.

Might use and Pre- and Post- backup commands to turn AV on and off. Discussing with the AV manufacturer to see their take on this.

Will let you know what happens.

OK it turns out that Sophos Antivirus has a little-known registry tweak to add an exclusion by process name. It's not in the GUI yet.

I implemented this and a backup of >1TB went from around 500MB/min to about 1400MB/min!
