Monday, Tuesday and so is mostly used when you dont have an autochanger.
When you do have one I recommend setting up Pools so then reflect your
retention policies. In my setup we:
* Keep full backups for a year (run monthly)
* Keep differential backups for a year (run weekly)
* Keep incremental backups for 6 months (run daily).

This translates into 3 Pools, Full, Differential and Incremental. On
these pools the retentiontime is set and then automatically move back to
Scratch-pool when retention-time has expired. So all "fresh" volumes
just goes directly into Scratch pool.

Bacula will try to "fill tapes completely" e.g. fill mondays's tape with
tuesdays data if not explicitly configured otherwise.

Ok, you have to manually move your tapes into the tapedrive (mtx -f
/dev/changerdevice load 0 <slot> ) and dd some data onto it. That'll
erase the "label" on it. The thing is that this is most likely the
second time you ran "label barcodes" and each tape can only be labelled
once, then you need to manually erase it to get it back in.

label barcodes slot=<slotnumber>

That is how its done.. if its all in your changer then a few lines of
shell-foo can do it.
