how can i copy a VM from one proxmox backup server to another proxmox backup server without adding a datastore?

[se_marc]

Hi all,

Is there a good way to copy a VM from one PBS instance to another?

I downloaded all the files from the 1st PBS instance which is using ZFS



the second PBS instance is also using ZFS.

i copied the files to /mnt/datastore/pbsPool/vm/500/2022-12-29T13:10:03Z

i changed ownership of 500 recursively

root@pbs-1:/mnt/datastore/pbsPool/vm# chown -R backup:backup 500

renamed the image files to /fidx

root@pbs-1:/mnt/datastore/pbsPool/vm/500/2022-12-29T13:10:03Z# mv drive-efidisk0.img drive-efidisk0.img.fidx
root@pbs-1:/mnt/datastore/pbsPool/vm/500/2022-12-29T13:10:03Z# mv  drive-ide0.img drive-ide0.img.fidx
root@pbs-1:/mnt/datastore/pbsPool/vm/500/2022-12-29T13:10:03Z#

now when i look in the second PBS GUI, I don't see VM 500.

What can i do to make it show up in the GUI?

i needed to copy the `owner` file from another vm backup and it shows up now.

root@pbs-1:/mnt/datastore/pbsPool/vm# cp 114/owner 500/

now im running into the issue that the new PBS instance cannot verify the VM

2022-12-29T10:16:18-05:00: verify pbsPool:vm/500/2022-12-29T13:10:03Z - manifest load error: unable to load blob '"/mnt/datastore/pbsPool/vm/500/2022-12-29T13:10:03Z/index.json.blob"' - unable to parse raw blob - wrong magic

I would add the 'source' PBS as remote on the second PBS and just run a pull with group-filter to the single vm:
`proxmox-backup-manager pull <remote> <remote-store> <store>`

I hope this helps!

if the vm ID of the source PBS is the same as a vm ID on the destination, will it overwrite the current VM or is there a way i can change the VMID on either?

 

[Stoiko Ivanov]

the first workaround for this that comes to mind is to create a namespace on the destination and pull into that (see the `--ns` parameter)

I hope this helps!
