Restoring using proxmox-backup-client within a docker image

[reto]

Currently there is no proxmox-backup-client release for OSX, so I thought I just use a docker image. Unfortunately I'm unable to restore files from within the docker environment.

The error is:

proxmox-backup-client  restore host/REDACTED/2022-02-12T01:00:11Z REDACTED.pxar.didx restore
Error: Operation not supported (os error 95)

My version:
proxmox-backup-client version client version: 2.1.4 server version: 2.1.4

Docker image: https://hub.docker.com/repository/docker/retoschuettel/proxmox-backup-client

I'm having the same issue. Still looking for a solution (I'm not using the Docker container above, I'm just using a Centos 7 Docker Container.)

@CSA what host OS are you using? Also Mac?

I'm actually trying to deploy a docker container with proxmox-backup-client installed. It backups no problem, just can't restore with the same error that you have.
running it in a LXC ran with no problems (backup and restore) and direct install on Debian VM worked great!. Centos7/8 was a bit of a pain and didn't work well in the end for me. I will most likely just continue building the LXC to backup other OS's

What I mean is: What OS is the docker engine running on? Centos?

Debian:Bullseye Works perfect. Let me know if you need help I can send you the LXC

My setup is:

• Mac OSX ist the Host (docker Engine)
• And within the Docker image Debian is Running
  • -> restore fails with the error above

I'm wondering, if a Debian/Debian (Docker) combination would work for restores. If I understand you correctly, you tried LXC and direct install, which both worked for you.

It has to be a dependency issue in the Docker container. I've tried Bullseye and Stretch in a Docker container without any luck. Try deploying a Debian LXC it will work right away. if you also use PVE it should be a very easy deployment. Good Luck!

Noticed in another thread https://forum.proxmox.com/threads/e...t-operation-not-supported-os-error-95.109600/ that the /tmp directory needs to be writeable.

My working docker compose looks something like this:

version: "3.7"

services:
  pbc-appdata:
    image: retoschuettel/proxmox-backup-client:latest
    container_name: pbc-appdata
    hostname: appdata
    restart: unless-stopped
    command: /config/pbc.sh
    tmpfs:
      - /tmp
    environment:
      - PBS_PASSWORD=<password>
      - PBS_REPOSITORY=root@pam!token@pbs:datastore
      - PBS_FINGERPRINT=<fingerprint>
    volumes:
      - /appdata:/appdata:ro
      - /appdata/pbc-appdata:/config

My bash script simply runs proxmox-backup-client with appropriate arguments.

For those after an automated docker (Cronjob'd) I chucked something together here which should be relatively straightforward to use.
