Hi Steve, The only difference in "snapdiff backup" than any other remote file system backup is that up front part. With Snapdiff, we use 2 snapshots to determine what has changed instead of traversing the remote filesystem. Once we get past that, it is just like any other backup. So, options like RESOURCEUTIL which increases the number of sessions with the server (can be read 'threads per volume') can be used.
