EPERM error with Synology NFS

[mapen]

Not sure how to delete, i gave up and decided to go unprivileged. Figured that PBS needed to have root & backup user privileged towards the NFS share.

Hello,

Make sure the “Squash” option is set to “No mapping” or “Map all users to admin” if you're using root access.
it can be missing root privileges. PBS or PVE may require root access to write metadata or backup chunks.
If root is squashed (mapped to nobody), you’ll get EPERM when trying to write.
Ensure NFSv3 or NFSv4 is enabled depending on your setup.
