The command line tool bextract can read tapes, but it can't read encrypted
backups, so you would need to dump the catalog unencrypted. That may be OK,
because all the information within it is stored on the tapes unencrypted
anyway (Bacula only encrypts the contents of the files, not the filenames
etc).
Alternatively, you could use the Write Bootstrap option in the catalog backup
job and keep a copy of this file for use with the restore command in bconsole.
You need to keep a copy of each backup, since it records the information about
the tape.

Maybe encryption is non-deterministic?
