Just wanted to post that we have tested a configuration that increases speed on the backup of clustered volumes.

We were getting backup speeds with ARCServe 9.01 of only 32,000 KB/min.

We had the cluster volumes with compression enabled. We re-created the volumes without compression and now get an average of 277,000 KB/min.

So the compression on the clustered volume is an issue.
