How can we use a Datastore from previous PBS installation (USB drive)?

[nicedevil]

Hey guys,

I have a friend that doesn't have an other possibility then doing his backups to a USB connected HDD with proxmox backup server.
This server is also virtualized on the same host as proxmox ve is running. I know it is not recommended but he has no other PC for just doing the backupjob.

At this point everything is fine and working well for him over 2 months now.

If the only PC he got fails (hardware defect or anything like that) the PBS is "gone".
If he will then get a new PC and setup PVE and install a new PBS instance with the mounted USB drive from the previous PBS VM, how can we mount the files from the USB drive correctly to be integrated as it would be on creating a new datastore on an empty drive?

Is that even possible?

Ty in advance.

I would backup that PBS VM as a vzdump backup to a partition on that same USB-HDD. Then he could first restore the PBS VM from the vzdump-archive file and then use the PBS VM to restore the other guests. Also don't forget to backup your PVE hosts "/etc" folder so he also got a backup of his config files like the /etc/fstab for mounting the USB HDD again.

so I guess that should be done with CLI and not with the webui right?

You can create vzdump backups using the wrbUI. For /etc backup you would need to use the cli.
