Migrate a vm backup from a PBS to another

[f.cuseo]

Hello.
I have two pve clusters each with his own backup server.
I have moved some vms from one cluster to the other, and I would like to move the vm backups too, so I will have all my retention. I have searched but not found anything like "vm backup export" and "vm backups import".
Is this possibile ? Thanks, Fabrizio

You need to connect them as Remotes and then setup Sync Jobs.

If you are going to mix VM populations on your PBS, and they are all in the range vm/100+, I recommend you look into Namespaces as well.
If this is a one-time transfer, Namespaces might be overkill,

Yes, sync jobs are one of the solutions, but for one time transfers I think that is better a simple command like "pbs backup transfer vmgroup destinationserver".
Namespaces are great, but I don't know which vm I will transfer a day.... so grouping them is not possibile.

I guess I didn't understand your question well enough.
Are you looking for something like PVE-zsync?

With the Proxmox VE ZFS replication manager (pve-zsync) you can synchronize your virtual machine (virtual disks and VM configuration) or directory stored on ZFS between two servers. By synchronizing, you have a full copy of your virtual machine on the second host and you can start your virtual machines on the second server (in case of data loss on the first server).

Sync jobs are the solution to this. Create one job without schedule, then filter by the VM/CT you want to sync, press run to get those backups to the destination PBS. You can do this any time you want with any VM/CT at any time. If you want to do it via CLI, take a look at this docs [1].
