Maybe another option would be do a migrate job to external media for enough of the volumes that contain the incrementals. That way If things go completely south I could still restore. I’ll have to take a look at the schedules. I’m feeling like the first thing bacula is going to do is determine that incrementals are missing and initiate fulls. Is that sounding right?
Bacula will not initiate a FULL backup because incrementals are missing or have been moved elsewhere. It will self-initiate a FULL backup if it cannot find a valid prior FULL backup job *in the Catalog*.
(Side note: You might look into VIRTUAL FULL jobs here and see if that is of any use to you.)
My backup strategy varies retention times for different job levels such that there is always overlap. The higher the level, the longer the retention. I run nightly Incrementals which are kept for a month, weekly Differentials that are kept for two months, and monthly Fulls that are kept for four months. I can point-in-time full restore to a specific day anywhere in the past month from no more than eight Jobs (one Full, one Differential, and no more than six Incrementals).
Your incremental backups should be small, and should have the shortest retention times. If considering migrating/copying some jobs to external storage, I would suggest migrating the higher-level jobs that are larger and have longer retention, rather than the incrementals. This will make better use of your online storage while not impacting your ability to perform immediate small, near-present-time restores. I copy only my FULL backups to air-gapped external media; Differentials and Incrementals are kept online until pruned. It literally takes me longer to *set up* a small restore of a few recent files than it does to actually perform the restore.
