Hello David, As nobody can seem to help me with this issue, can you provide a link to the version before 6.3.2.204 please.

Thank you David for your quick responses. There are no issues with the drive assignment. I have verified it. What is strange is that it appears to be working despite the error. I check the backup storage tab and drill down to the individual backups; they appear all there. As I said, I am restoring to see if it is ok, but I don't expect any issues. By the way, this was fine before those aforementioned versions where installed; so years (yes years) of no issues with respect to this. Also, it is very strange that both sites (completely independent of each other) exhibited this same behavior right after the update.

They each have their own USB drive. It is never moved, and it does have a drive letter assigned.

It is to a usb attached drive.
