What is the best approach to backup Docker and appdata for a user who use mergerfs + snapraid ?
Docker image are on OS disk
Appdata folder ( docker container config files ) is on another ssd
My openmediavault disk is backup with "backups" plugin with fsarchiver.
I do'nt know how to do with the Appdata folder. I put this folder on ssd out of the mergersfs/ snapraid disks beacause I don't want spread little files on it.
Are tthere a way to backup Appdata on one big file I can spread on my mergerfs/snapraid disk ?
