Just curious... What does the perl script do better/more than the
pure Amanda-equivalent with DLE's like:
zorn /export/users-a /export/fssnap/users {
users-tar

Indeed. That's why, even if I could split backups over many tapes,
I still prefer to keep the backup-units manageable, by using the
include/exclude features in the dumptypes to break up the large disks.
