hi team
there is a way to Backup only the Hard Disk of a VM ?
* i have 1 disk for the VM
* 1 disk to store DATA on it


i will like to backup only the DATA disk
send the backup on another node on cluster and use the backup with another VM
thx

Hey,

when editing the disk under "Advanced" you can check "Backup" if you want the disk included in backups.

thx! so i did backup the hard disk with data, do you know if i can mount the backup disk in a new VM?

Just copy (cp, rsync etc.) the virtual data disk file to a shared storage location & give it a unique name, and from the other node use qm disk import to get it into that VM.

thx, i think i understand now, i have a last question

On proxmox doc i see this:

Description	Plugin type	Level	Shared	Snapshots	Stable
Proxmox Backup	pbs	both	yes	n/a	yes

By default proxmox Backup go on local storage who can't be shared, what do they mean with that(Shared : yes )?

 

[Hannes Laimer]

PBS is (like PVE) running as a service on some hardware, multiple PVE hosts can use the same PBS server, that's why is says shared.
