Then you should put all your new tapes in the Scratch pool during
labeling, so Bacula can take one to the selected pool when required.
Finally you should configure the "Recycle" pool parameter pointing to
the Scratch pool, so all your unused tapes will return to it, closing
the cycle.
When carefully configured it will automatically rotate all your tapes,
which is good for them.
The rule of thumb for the tape backups in Bacula is to use as few pools
as possible. Especially for catalog backup which is technically
redundant (unneeded, see below) and you save it for time saving only
during recovery.
If you have a single tape drive then you are limited to a single pool
usage at any given time, and all your jobs which require another pool
will wait. When your backup window is tight then you want to avoid this.
I personally create tape pools based on required retention, i.e. Tape1W
or Tape1M and join all the pools with similar retention time.
I think I have to start over with pools.
my approach with pools daily, weekly, monthly doesn't work so far
I see various issues, maybe related to defective tapes also.
Volumes that are in mode "Append" are loaded and not written to as in:
25-Jun 12:52 samba-sd JobId 2840: 3304 Issuing autochanger "load Volume
CMR945L6, Slot 6, Drive 0" command.
25-Jun 12:52 samba-sd JobId 2840: 3305 Autochanger "load Volume
CMR945L6, Slot 6, Drive 0", status is OK.
25-Jun 12:53 samba-sd JobId 2840: Volume "CMR945L6" previously written,
moving to end of data.

I "Purge" them, mark them as "Append" ... doesn't work.
I don't get a "weekly" run to write to 4 tapes in a row without my
intervention. Bad.

Yes, I should show my config.
I assume dropping the configfiles to my nextcloud isn't appreciated as
then the mailing list archives won't contain all information ...
my director conf is 863 lines long, I assume I should pick out the
relevant parts. Will try to.
