large file unc backup issues after upgrade to 4.1
We updated to version 4.1 last week and since then one of our backups has been failing.
We have one backup that does a full backup on 2 databases, one small and one very large (8-9gb). Both backup to the same unc file share but the large database fails with the errors below. It does create a 1kb .sqb file however?
One other backup fails which is the transaction log backup for the large database above.

Any ideas much appreciated
