Netbackup 6.5 System Resources

Is there a way to reduce the impact of running Netbackup 6.5 in a way that when it runs it's full backups it would run as low priority and/or conserve disk I/O  ? The goal is not the finish backups jobs quickly but to conserve system resources.


Thank you,

It's an unusual question. Most people want to make their backups go faster.   :-)

And to that point, i'd recommend you make the backup go as fast as possible so it finishes quickly and the heavy I/O load is off the client as fast as possible.

If you have an EMC CLARiiON array, you could apply a schedule based QOS policy.

Could you provide some background to this? There may be an alternate solution.

The story is this...

We a file server running 2003 server connected to a 1942GB volume via iscsi on an equalogic SAN. This volume is a MBR partion and almost reaching 2TB limit for this type of partion. We are backing up across the network to another disk array. File server locks up when we have users accessing files and running a full backup at the same time. The only solution has been to kill the backup job. We are looking for some work arounds.
EqualLogic snapshots could be just what you need. You can use the SAN-based snapshot to take a point-of-time copy of the 1942GB volume and mount that on the backup server and backup directly from there. This takes all the load of the file server and should solve your problem. More information here: http://www.equallogic.com/solutions/default.aspx?id=5847

I believe that some EqulaLogic boxes were sold with snapshot software included, so you may already have the software you need to do this.
We are already doing snapshots. They work great. We also wanted to have a full normal type backup of the data on disk just incase. Your suggestion is a really good approach to the problem. Are there any other ones? can netbackup be configured in a way that it would run as low priority or maybe the backup job stop while business hours and resume after hours?
