Backup of Journalreceivers

We run a backup (savlib)of the journal library twice a day. We run
one at noon and the other after the nightly backup of the database.
Our operators will then delete the saved receivers after the backups.
The backup done at night is really a worthless backup for the
journals. We probably would never use these receivers since we backup
the database at the same time. We use this backup just to get the
receivers to a saved status so they can be deleted. We use CL
programs to perform the backups.
