I'm having a difficult time creating a backup-to-disk folder in Symantec Backup Exec 12.5 and Backup Exec 2010. The backend storage is a Nexenta/ZFS-based NAS filer sharing the volume via CIFS. I've also seen the issue on other *nix-based NAS devices.
I've attempted mapping the drive, providing the full paths to the folder, etc. I can browse to the share just fine from within Windows, but Backup Exec fails to create the B2D folder with different variants of a
Unable to create new backup folder. Access denied error.
I've attempted creating service accounts in Backup Exec to handle the authentication, but nothing seems to work. What's the key to making this work?
Update: Here's the event viewer log:
An error occurred while processing a B2D command. Changer: CreatePath() CreateDirectory1 failed (\\storage1\vol1_backup\). Error=5
