Hi Everyone

I need some help

I’m currently selfhosting some of my applications on Digital Ocean and i run a container using Portainer CE. I was wondering how you guys keep backups for the applications running on docker.

I’m currently using Digital ocean’s snapshots feature but is there a better way i could use, any help on this is highly appreciated.

    Most of mine are lightweight so private repos on git.

    For big data I have two NAS that sync on the daily.

    Almost everything I run is a Docker container, so I made /var/lib/docker a btrfs subvolume, and then I make every day incremental snapshots (cron job) and copy them to a secondary disk (also btrfs, using btrbk). Since they are btrfs snapshots they don’t use a lot of disk space and if I really need to rollback an entire day I can

      I use an Ubuntu vm for all my containers in proxmox and make backups of the vm onto my zfs pool

    Proxmox Backup Server (PBS) snapshotting all my VM’s / LXC’s.

    External VPS’ and anything that can’t run PBS-Client I am rsync’ing important data into my home network first, then doing a file based backup of that data to PBS via PBS-Client tool. All this is automated through cron jobs.

    Those backups then get sync’d to a 2nd datastore for a bit of redundancy.

    When backing up Docker volumes, should not the docker container be stopped first.?? I can’t se any support for that in the backup tools mentioned.

    I have bind mounts to nfs shares that are backed my zfs pools and last snapshots and sync jobs to another storage device. All containers are ephemeral.

    I just run a pg_dump through kubectl exec and pipe the stdout to a file on my master node. The same script then runs restic to send encrypted backups over to s3. I use the host name flag on the restic command as kind of a hack to get backups per service name. This eliminates the risk of overwriting files or directories with the same name.
