docker-vackup VS sanoid

I used vackup [1] that’s been obsoleted but still works for me. However, you still need to turn of the container temporarily.

Will look into that one as the recent docker volume backup extension seems to only be for docker desktop https://www.docker.com/blog/back-up-and-share-docker-volumes-with-this-extension/ unlike its origin https://github.com/BretFisher/docker-vackup.

Docker came up with https://hub.docker.com/extensions/docker/volumes-backup-extension, to be used in Docker Desktop 4m10 or up, which is the continuation of Vackup https://github.com/BretFisher/docker-vackup.

I have also have been using Vackup for a RPi4 running docker that doesn't have ZFS.

Look at using something like vackup occasionally to backup volumes. Or occasionally run application level backups (mysqldump, pg_dump) that get stored to some location outside docker.

I’m on the other end of the spectrum. I like knowing the flags and settings I use to create the pools.

For snapshots and replication take a look at sanoid (https://github.com/jimsalterjrs/sanoid).

I use a combo of PBS and ZFS with Sanoid. The ZFS snapshots are nice because you define it all in a config file with frequent, hourly, daily, weekly, monthly snaps retained however you want. Importantly I use that on the root pool as well as my data pools. With PBS I have a custom retention config and have it backing up VMs and LXCs every couple hours. The PBS dedupe functionality makes it possible to keep full backups going back ages with minimal storage consumption, just the changed blocks. PBS is running inside a VM yes, but it’s storage is on another pool.

No, it's written by the developer of Sanoid and Syncoid. The foremost open source ZFS snapshotting tool. He contributes on this sub all the time.

Hi there! Not so much to answer your questions, but are you aware of Sanoid and syncoid? It does backup and remote Sync in the most seamless way. Perhaps this would solve some of your concerns...
