Does backups on different namespaces share chunks ?

[Fathi]

Hielo,
Does backups on different namespaces or on Root of datastore and namespaces under that Root share chunks in terms of deduplication ?
If I backup a server on the Root of the datastore and then change backup destination to a namespace under that Root, does Proxmox Backup Server take into consideration the common blocks to the two backups and just store the new changed ones ?
TIA.

Yes, different namespaces on the PBS share the deduplication of chunks.
