Hi Uwe,

I don't want to wipe the whole tape.
Only data from one specific full backup job.
I want to write another full backup of the same client to this tape.
I don't have enough space for two.
I want all other backups of other clients present on this tape to remain intact.
Is it at all possible with LTO-4 and Bacula?

Thanks,
Adam

Hello Adam,

if you don't mind having to re-label the volume aftwards a

delete volume=<volume name>

followed by an

mt -f /dev/st0 weof # insert your tape device here

should reliably wipe your tape.

All the best,

Uwe

Bacula console commands "delete" and "purge" only seam to affect the catalog
database.

For storage I'm using LTO-4 tapes which unfortunately don't support LTFS
yet.

I think ideally I would like tape space to be freed up and I'm ok with the
job still being listed.

As long as Bacula is aware of the situation and e.g. doesn't try to access
the deleted data later.

Obliterating both the data and the job info as if they've never existed is
also fine.

Please advise.

Thanks,
Adam
