I agree. It would be nice if there was a 'clone volume' command that
would create a copy of the tape (or backup file) and create new records
for the associated catalog data with pointers to the second volume. I
used to work with a Legato system and I'm pretty sure that it had that
feature. Or maybe Bacula does have that and I just haven't found it
yet.

USB drives are fairly cheap these days, and it would be simpler and
faster to work with volumes copied onto disk rather than tape. No
comments on reliability though.
If you already have a tape drive though and you don't really need to
have immediate access to 'Volume_25' out of 50 volumes (as opposed to
waiting for the tape drive to seek to the right position), then buying
new hardware isn't really necessary.
I do intend to automate the process as much as possible. The
'RunAfterJob' script will take care of doing the appropriate cp's. I'll
have to add some smarts to the script so that it doesn't overwrite
something that it shouldn't. But that should be a simple check. Now
all I need is time to actually work on it.....
