Re-Inizialization datastore

[Canapla]

I'm a quite newby in pbs and I need an help.

I have a PBS making backup on an NFS datastore and it have work good for a while. Now a colleague have made a mistake and delete some folder (many) inside the .chunk folder. Now all the backup give me error cause pbs doesn't find that folder anymore. I can't wipe disk cause it's an NFS drive. Is there a way to re-initialize the drive so to recreate the folder and start from 0?

Thanks in advance

Go here to Managing Datastores. Read the entire section.
https://pbs.proxmox.com/docs/storage.html#datastore-configuration

It says how to remove a datastore.
(proxmox-backup-manager datastore remove store1)

It also says what files/folders the datastore consists of. (.chunks)
To resolve a corrupt .chunks, delete the .chunks folder from the NAS.
(Expect this to take an unreasonable amount of time. Just let it go.)

Then you need to set them back up.
If you run into a name conflict when you re-add the datastore, either give it a different name, or update the /etc/proxmox-backup/datastore.cfg manually.
