Quick Q - is TRACKER.EXE running on the box?
Goto RUN and type MSCONFIG and press return.
Check the startup tab - if tracker.exe is ticked, untick it!
What type of files are you backing up? Larger, small single files?
compressed files?

Subject: [Veritas-bu] Backup Speeds
Hi all,
I have a Win2k3SP1 file server cluster member that will not back up at any
reasonable kind of speed - it will sometimes kick off at about 12MB/s and
can drop as low as 3MB/s (avg is about 5MB/s). It backs up over Gbit
Ethernet, and so I would expect to be seeing somewhat faster speeds - I have
another server that does not drop below 16MB/s.
The policy is split into 3 streams, with multiplex set at 2 (when I set it
to 3 I have Paged Pool errors on the client followed by an OS hang.
(Rectified as of today with a reg key). Occasionally one of the streams
when it kicks off will sit around about 700K/s (always the same
drive/folders as well) and still be running first thing in the morning...
I've even shuffled the jobs around so that this job is the only one running
for a couple of hours.
I've checked all the usual stuff - link speed/duplex (manually set at
1000/Full), virus scan (disabled), windows Open File backups have been
disabled for this client as well, as I was having the odd snapshot error.
Master server is Win2k3SP1 5.0MP3 with all clients at same level. 2xLTO2
drives in a STK500SL library.
Any ideas? I'm stumped - just to add further confusion, both cluster nodes
exhibit the problem to a degree. Argh!
Thanks
