Error: Restore job failed Error: NFS status code: 30

I recently saw the below error occurring for a customer attempting to restore a backup from their NetApp SAN using Direct NFS Access. Backups using Direct NFS access were performing without issue but the restores would only successfully complete if the proxy could use the network mode (NBD).

“Restore job failed Error: NFS status code: 30
Read-only file system.
Cannot get count from WRITE3res.
Failed to download disk.
Agent failed to process method {DataTransfer.SyncDisk}.”

Direct NFS Access Error

Turns out the backup proxy was only configured with read permission not read/write.

According to the Veeam User Guide the backup proxy must have ReadOnly/Write permissions and root access to the NFS datastore.
