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.

Uuuh…timeshift and borg??
Hey that is the plot to First Contact.
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
ZFS snapshots.
duplicati to take live, crash-consistent backups of all my windows servers and VMs with Volume Shadowcopy Service (VSS)
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.
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.
On Proxmox i use for my Backup Solution - Hetzner Storage Bix
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.
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.
Kopia has been great.
I use duplicati to backup to a secure off site location. Useful for something like vaultwarden.
Most of mine are lightweight so private repos on git.
For big data I have two NAS that sync on the daily.
Unraid with Duplicacy and Appdata Backup incremental to Backblaze
Cronjobs to backup important folders to a separate disk
Git repo(s) for services & configs with weekly automated commits and pushes
I do the reverse… all configs are ansible scripts and files and I just push them to the servers. That way I can spin up a new machine from scratch, completely automated within minutes… just the time it takes the machine to set itself up.
