Interrupted pruning/compacting

[sophie-h]

It does look like borg prune has to start all over again if it is canceled while running in 1.1. Is that correct?

Will borg compact in borg 1.2 be able to continue where it was left off?

I'm currently trying to prune hundreds of archives but there does not seem to be an easy way to complete this.

if you interrupt it before it commits, yes, all will start from the last valid commit before that (IIRC).

there are 2 commits (borg < 1.2) or 1 commit (borg >= 1.2):

• after logically deleting the archives (all borg versions)
• after compact_segments() (only in borg < 1.2). in borg >= 1.2, this is separated into a borg compact run.

Thanks for the clarification. How difficult would it be to add something akin to --checkpoint-interval for regular commits during prune and compact?

didn't look yet, but let's continue in #6284.

the easiest way to avoid having to delete a huge amount of archives is of course running borg prune regularly.
