Restore host backup to vm on PVE

[mwelters]

Hi,

with proxmox-backup-client I backuped from inside a (VMWare-) virtual-machine to a namespace on PBS.
Command-Line was:

sudo proxmox-backup-client backup it_server_de.pxar:/ --repository server-rz@pbs@192.168.132.30:pbs-local --ns Server

In PBS the Backup shows fine as "Hosts/hostname" with savepoints. Looks like the "vm/100" backups from a Proxmox VE host...

But in the Proxmox VE Gui, the Backup does not show and cannot be restored (the vm/100 backup is visible).

For testing, I created a new backup of the same Machine with "backup-type=vm" ....

sudo proxmox-backup-client backup it_server_de.pxar:/ --repository server-rz@pbs@192.168.132.30:pbs-local --ns Server --backup-type=vm

Does not show up in Proxmox VE Storage either...

Would be a real feature, if I could backup (any hypervisor) - Virtual Machine from inside to migrate it to Proxmox...

Any Ideas hints where to enable this ?

VM backups aren't storing the files/folders of the root filesystem. They are storing blockdevices, so backups of your files from within the VM wouldn't be useful. And then VM backup also needs to store the VM config file, which defines what the VM hardware and so on should look like.

For migration, create a new VM and then try the "qm importdisk" to import a vmdk.

this won't work like that - for VMs, PVE expects a block-level backup (with fixed-index representing a raw disk iamge), not a file-level one (with dynamic-index representing a pxar archive of a directory tree).

the following could work, but might require some manual touch-ups

on the vmware side:
- boot live CD In VM
- backup full disk(s) as fixed index

on PVE side
- create VM without disk(s)
- restore backed-up disk(s) as raw image file(s) using proxmox-backup-client
- import raw image file into VM (e.g., qm set XXX -scsi0 TARGET_STORAGE:0,import-from=/path/to/raw/image/file,...)

Ok, thanks you for the answers !

So I have to wait for VMWare support ;-)

sorry Fabian I must restore a backup as an image but dont find the command in the documentation

if it is an image based backup, just use `proxmox-backup-client restore` (or `map` and dd/qemu-img convert/..)
