NT metadata is lost when backing up via NFS. If you perform a backup via CIFS of files with UNIX-style permissions, the permissions are saved and restored. Additionally, WAFL keeps a DOS-like archive bit on UNIX files (as well as NT files). NT based backup apps can leverage this to perform incremental backups of UNIX files.

I would appreciate if someone could clarify the issue of metadata preservation during network backup of filers data. Lets assume that I have a share with NFS/CIFS access. If backing up this share from NFS will the CIFS metadata preserved upon restore? If backing up this share from CIFS will the NFS ACLs be preserved upon restore? Thnaks, Itzik
