hi peeps.

Im early on my selfhosting journey and managed to setup some things as a test in docker. the main service im looking to run is ERPNext. after a while I got it up and running so now I want to back this up including all the customization I did in the app.

where to start with this? any intuitive guide?

    My docker files, configs, and volumes are all kept in a structure like:

    /srv  
 - /docker  
 - - /syncthing  
 - - - /compose.yml  
 - - - /sync-volume  
 - - /traefik  
 - - - /compose.yml  
 [...]

    I just backup /srv/docker, but I black list some subfolders for things like databases for which regular dumps are created or something. Currently the compressed / deduplicated repos consume ~350GB.

    I use borgmatic because you do 1 full backup and thereafter everything is incremental, so minimal bandwidth.

    I keep one backup repo on the server itself in /srv/backup - yes this will be prone to failure of that server but it’s super handy to be able to restore from a local repo if you just mess up a configuration or version upgrade or something.

    I keep two other backup repos in two other physical locations, and one repo air gapped.

    For example I rent a server from OVH in a Sydney data centre, there’s one repo in /srv/backup on that server, one on OVH’s storage service, one kept on my home server, and one on a removable drive I update periodically.

    All repo’s are encrypted except for the air gapped one. That one has instructions intended for someone to use if I die or am incapacitated. So it has my master password for my password database, ssh keys, everything. We have a physical safe at home so that’s where that lives.

      My docker files, configs, and volumes are all kept in a structure like:

      Over the years, I have gravitated to keeping docker compose, configs, et al, in structured directories in lieu of docker just splattering the HDD willie-nilly, with configs anywhere and everywhere. It sure makes problem solving much easier when you can go directly to where each component is instead of spending 30 minutes trying to locate where docker put everything.

      Doesn’t rsync do incremental? I keep hearing about borg but not sure I want to commit to learning a new app

        Yes but rsync isn’t a “backup”.

        Spouse i inadvertently deleted a heap of stuff last month. Rsync would happily reflect that change on the remote. Borg will store the change but you can still restore from an earlier point in time.

        A docker volume?

        I only use bind mounts, and in that case you can put them where you like and move them while theyre not mounted by a running container.

        Docker volume locations are managed by docker, and i dont use those so not part of the above plan.
