Can't run quick maintenance

Support
1

Hi all - I am running automated kopia backups via cron every morning at 1am. I set up my script to run a quick maintenance most days, and a full maintenance every Sunday. However, I noticed that it runs a full maintenance every time, and I can’t seem to figure out why. If the full maintenance also performs the same tasks as the “quick” maintenance I don’t really care, since it doesn’t take any amount of time, but I’m trying to understand the behavior. Further, what does it mean to schedule a maintenance? Kopia isn’t running as a daemon, so how would a scheduled maintenance run every hour if Kopia is only invoked once a day? Thanks in advance!

Hi jrdemasi, looking at kopia’s source code it seems that if you are using the new repository format and kopia version >= 0.9 then invoking maintenance via CLI will always result in a full maintenance run.

To your second question: If kopia is run in (continuous) server mode then it will be able to invoke tasks when they are due. If kopia only runs on demand it will only be able perform these tasks each time it’s run.
