How are you backing up your database data for docker containers? (postgres etc)

There is no ultimate solution. For my KVM Systems where docker is running inside a VM I backup the complete VM.

There are however multiple approaches to backing up data volumes. There does not seem to be the preferred solution though.

Zitat von robster

How are you all backing this data up? I found this pretty cool looking thing `prodrigestivill/postgres-backup-local` but when I search for it in the docker interface in OMV it doesn't show up. So I assume people ARE backing up. How are you doing it?

Maybe you want to move towards using docker-compose/stacks with portainer. Then you can use the suggested docker-compose.yml like shown here:

btrfs snapshots sent to external backup drive. In my case there is not much change in daily use, so I do the backup to a ext drive only about once a week or sometimes after 2 weeks.
