Hi there,
I am pretty new to Proxmox and deeply impressed by the quality of many
aspects of its design and implementation.
In my testing I observed that in case I have multiple PVE Clusters and
perform backups to a single datastore on a single PBS I experience a
lack of namespaces.
Why a single datastore on the PBS for multiple PVE Clusters?
For reasons of efficiency and avoidance of fragmentation I would like to
use a single RAIDZ2 as a target. The problem now arises that both PVE
clusters see the same "vm/100/{dateTime}".
What about prefixing the backups with the Cluster-Name e.g.
"pve1/vm/100{dateTime}"?
Is there something I overlooked sofar?
Regards
ppa. Martin Konold

Hi Martin,
you can create multiple datastores on one zpool, just create an
additional zfs dataset and configure the second pbs datastore on it.
This way all data is stored on the same RAIDZ array, if this is your
intention.
If you want use the deduplication feature of pbs across backups of
multiple clusters, I have to disappoint you. Afaik the deduplication is
per datastore.
Another "solution" would be to manually avoid overlapping VMIDs, but
this would be error-prone and means a lot of work in an existing
environment.
I would create one backup datastore per cluster and call it a day.
Best regards,
Jan

Hi,
I think it's on the roadmap.
(could be great to have some king on namespace too on storages, to be
able to share them across multiple cluster)

You are right!
