    Backup a Raspberry Pi to Proxmox Backup Server using the Proxmox Backup Client

This works on a Pi 4, and should work on a Pi 3, but to work on a Pi Zero you would have to figure out how to compile your own client.  More info in this thread on the Proxmox forums.
Determine if your Pi is 32bit or 64bit

Run the following command.  If you get arm64, it's 64bit, otherwise you'll see armv7l which is 32bit.
uname -m

Download a custom compiled version of the PBS client

Check for the latest release here.  Then wget the PBS client, depending on if you need 32bit or 64bit.
wget https://github.com/ayufan/pve-backup-server-dockerfiles/releases/download/v1.1.9/proxmox-backup-client-v1.1.9-arm32v7.tgz

Extract the archive and move it to /usr/local/bin or wherever you'd like:
tar xvfz proxmox-backup-client-v1.1.9-arm32v7.tgz
mv proxmox-backup-client-v1.1.9 /usr/local/bin/pbs_client

Create a new script to do your backups at /usr/local/bin/pbs_backup.sh  See the docs for more info on authentication:
#!/bin/bash

export PBS_REPOSITORY=pbs_client@pbs@pbs.local:mydatastore
export PBS_PASSWORD=mypassword
export PBS_FINGERPRINT="02:39:10:2d:23:59:5a:29:13:95:43:ad:d9:e7:d2:13:e5:f7:3e:fd:10:2e:38:9b:12:a3:1e:9e:4a:32:de:23"

apt clean cache
cd /usr/local/bin/pbs_backup
./proxmox-backup-client.sh backup root.pxar:/

Setup a cron job to do daily backups

Create /etc/cron.d/pbs_backup with:
# Run every day at 00:05
5 0 * * * root /usr/local/bin/pbs_backup.sh
