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.

For databases and data I use restic-compose-backup because you can use labels in your docker compose files.
For config files I use a git repository.
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.
I backup all the mounted docker volumes once every hour (snapshots). Additionally i create dumps from all databases with https://github.com/tiredofit/docker-db-backup (once every hour or once a day depending on the database).
ZFS snapshots.
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.
Yes the containers do need to be stopped. I actually built a project that does exactly that.
Thanks, I will look into this.
I use Nautical. It will stop your containers before performing an RSYNC backup.
On Proxmox i use for my Backup Solution - Hetzner Storage Bix
A few hard drives that are stored offsite and rotate every few weeks.
Borgbackup, borgmatic to two backup targets: one in my home and a Hetzner Storage Box. Amongst other things, i include /var/lib/docker/volumes, covering the not-filesystem-bound mounts.
What retention do you run?
I’m setting up the same system, but don’t know how far back I need. Currently considering 7 daily backups, so I can restore to any point within the week, and 2-3 Monthly backups in case there’s an issue I miss for a real long period.entirely up to your feelings i guess - i run 7 dailies and 2 weeklies

Kopia has been great.
I use docker in Proxmox and i backup all container
I use an Ubuntu vm for all my containers in proxmox and make backups of the vm onto my zfs pool
Uuuh…timeshift and borg??
Hey that is the plot to First Contact.
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.
