Proxmox Backup Client in a Container

This was built to run on an unraid server, so here are some specific setup steps for that.

Setup

SSH into unraid and perform the following:

mkdir -p /mnt/user/appdata/pbclient && chown nobody:nousers /mnt/user/appdata/pbclient

Create the encryption key

docker run --rm -i -v /mnt/user/appdata/pbclient:/config kwatson/pbclient:latest proxmox-backup-client key create /config/client.key --kdf none

Perform a backup

You can use the userscripts application to setup a recurring schedule for this.

• docs.pxar:/data is a friendly name for the unraid share, and /data is where it's mounted in the container
• unraid@pbs\!unraid-agent is the API username
• PBS_PASSWORD is your api token
• --backup-id unraid-docs is a friendly name that's displayed under Content in the proxmox backup UI. Without this, it would default to the hostname of the container, which is different after each run.
• MYPBS is the ip or url to your proxmox backup server
• DATASTORE is the name of your datastore

docker run --rm \
      -v /mnt/user/appdata/pbclient:/config \
      -v /mnt/user/Docs:/data \
      -e PBS_PASSWORD=CHANGEME \
      -e PBS_REPOSITORY=unraid@pbs\!unraid-agent@MYPBS:DATASTORE \
      kwatson/pbclient:latest proxmox-backup-client backup docs.pxar:/data --keyfile /config/client.key --backup-id unraid-docs
