Hello. I am searching for a method to backup all the data and configurations of the dockerized mailcow incrementally.
I have already searched but didn't found a 'state of the art' solution.
How do you backup your containers and volumes?
I use the backup suggestions in the documentation, though it is not incremental:https://andryyy.github.io/mailcow-dockerized/u_and_e/#backup-and-restore-maildir-simple-tar-file
Also, I rsync my persistent volumes to another location for safe keeping.
