Now, during tape backup, users do not see any progress on the GUI. This 
can be particularly confusing on long running tape backups.

A simpler approach would be to only generate cache files for "finished" tapes (content 
will never change), while using the original catalog for tapes still writable. This should 
be much easier to implement?
