Backup migration between different namespaces

[Zlobniy Shurik]

I have some namespaces with different retention policies (e.g. daily backup for week, daily backup for month, monthly backup for year, e.t.c.)

Sometimes i have to change retention policy for some VMs. There is no problem assigning a virtual machine to a different backup task on Proxmox VE with a different namespace. But older backups for this VM remain in previous namespace.
Can I migrate backups of VM to new namespace in Proxmox BS? If this impossible now, can I make request to implement this feature in future releases of Proxmox BS?

It can be done using sync jobs: https://pbs.proxmox.com/docs/managing-remotes.html#sync-jobs

As stated above, it can be done with sync jobs + manual deletion from the source namespace. Currently, local sync jobs only allow to sync between different datastores (I'm still wondering why). You will have to add that PBS itself as a remote so you can copy snapshots between namespaces of the same datastore.

You could also do it simply by moving the backup index files in the filesystem, although you may need extra work to adjust owner or even filesystem permissions. Beware that GC task usually removes files that not in the place they are supposed to be, so test this first in a lab.
