restore to dumpfile

[TErxleben]

Hi,
I run a central PBS virtualized on a PVE host. The VMs of various other PVE hosts are backed up on this PBS. Now I would like to extract PBS-VMs there as a dump file on external media.
Gladly via CLI like this: restore-dump-from-pbs --latest <vmid> <destination>
Is that possible somehow?
I would also be happy with other, perhaps more elegant, ideas.

Do u wanna habe a second backup store?

I already have a second PBS in another location. Unfortunately it's poorly connected. I don't want to think about possibly being forced to do a restore from there. However, the things are electrically isolated and a fire cannot spread to them.
The idea of dump files on various external USB disks (changed manually) is, in the worst case scenario, still considerably faster than an external replication PBS. Above all, there is minimal administrative effort.
Simply pull the dump from the PBS onto various USB-disks, plug the disk into any (even new) target server and play the dump back with minimal overhead/dependency.
With this I would like to cover the eventuality that my entire PBS logic has a blackout.
Unfortunately, bad guys also target your backup concept.

a pbs is fast reinstalled and the datastore is similar to dumb files from the logical view. simply convert is not possible.

Sorry, I don't think so.
A PBS is anything but a dunp file.
What would be the problem with extracting a dumpfile from PBS instead of a bootable VM?
A dumpfile needs no PBS nor any other infrastructure. It can be restored on every PVE.

It seems there is simply no tool for this. In this thread just a few days ago somebody asked the same question: https://forum.proxmox.com/threads/convert-pbs-backup-vm-snapshot-to-regular-proxmox-backup.148002/
And nobody offered a solution other than restore on a PVE and back it up again.

As for restoring from a copy of your datastore, nothing hinders you to create vm and set up a PBS in it.

U can restore an image backup to stout and than use dd to write in an file. But it makes no sense.
