Glenn,

To retain both permission styles you'll need to backup using the local dump command, an NDMP enabled backup application or backup over CIFS. Backing up over NFS will not retain NTFS file permissions or DOS attributes.

If you back up over CIFS, not only are the UNIX and NT file permissions retained but we also backup the DOS file attributes and track an archive bit for files with UNIX-style permissions. If backing up over CIFS is your plan, have a look at our white paper on this subject:

Subject: Backups of both NFS and CIFS Directories

I have a new netapp that I am in the process of trying to set up
It will be supporting both NFS and CIFS Clients.

I was wondering if anyone knew how Backing up the Permissions
for the Two different permissions styles works with the different
backup styles ?

I am concerned that If I back the machine up "Wrong"
we would lose the permissions of CIFS users files.

        For example
        If I back the machine up with tar from a UNIX machine I know the
permissions will be lost.

        If I back it up with the built in backup command and then restore with
solaris ufsrestore
        It will also lose the CIFS permissins.

So what do I need to do to make sure that the CIFS permissions are saved ?

If this is a FAQ question or I just need to RTFM Please just refer me to the
appropreate
document. (With URL if avalable )

Thanks in advance
