Why does unraid stop my dockers every morning at 2am?

Recommended Posts

Very frustrating. No idea why it does this.


Here's the log from this morning at 2am. It eventually comes back on... 5-10 minutes later, but my server is connected to a 10gbe switch and serves over 10 people so random disruptions are pretty annoying.

Do you have CA Backup / Auto Update installed and set for 2am!? In order to backup / update Docker, CA has to stop them .

Oh gosh, I'm so smart. Thanks. Do you know of any way to back up without stopping the containers?

No worries. We all come a cropper of the decisions we make at setup only to find those decisions impact smooth operation sometimes.

AFAIK there is no way of backing up without stopping. If there was I am sure the CA dev would have implemented it that way.

You could just let all users know that each day there will be downtime. I’d say your only way forward if you don’t want to do that though is to choose a time of day when you have least usage (maybe 5am) to limit impact. Or you could reduce the frequency of your backups.
