Cache cleanup?

[troelsarvin]

On a server I have a large /root/.cache/rustic/xxx/data directory (19 GiB) which I'd like to somehow shrink . I've tried performing "forget" and "prune" without the .cache directory getting smaller. Is there something I can do to tame the .cache directory size?

From my experience not much you can do about it (cache is cleaned up automatically anyway) unless you stop using cache all together (--no-cache) but then all operations performance will hit the proverbial rock bottom.

Rustic caches repo metadata and cache size depends on factors like number of files you backup, numbers of snapshots etc. I guess you have millions of files in your backup?

You can always delete all cache by hand (it is fully ephemeral) but unless it contains some rubbish it will grow back again to its original size.

Hi @troelsarvin

There are two things you should check:

• Is the cache you are talking about really the cache of the right repo? The repo id can be shown using rustic cat config. This shows a json where you can find the id. If this doesn't match the id of your cache dir, you are talking about the wrong cache dir ;-)
• Have a look at the output of rustic repoinfo. Everything except data packs should be contained in the cache. This should explain the cache usage. If not, please post that output so we can have a look!
