I am new to PBS and have successfully backed up my pve vm's to it. Checking your documentation I can see how to backup files from my debian vps using proxmox backup client, my question is can I backup the whole vm, if so what's the syntax, your assistance would be much appreciated.
 
Hi,
I am new to PBS and have successfully backed up my pve vm's to it. Checking your documentation I can see how to backup files from my debian vps using proxmox backup client, my question is can I backup the whole vm, if so what's the syntax, your assistance would be much appreciated.
yes this is possible but there is no easy integration as for PVE and this depends on the tooling and configurations you use to create and operate the VM.

Further, it is up to you to guarantee a consistent state of the filesystem to be backed up and this will not include any runtime state.

In principle, you can use proxmox-backup-client backup <disk-name>.img:<path-to-block-device> to back up the contents of a block device, or use the same to upload a chunked version of e.g. a qcow2 image. If you want to have file level backup, you can create these from within the VM (if Linux based) using the client as described in the docs https://pbs.proxmox.com/docs/backup-client.html#creating-backups

You probably also want to backup your VM config and other related files to be able to restore easily.
