@John - any more info or links on this "Snapmirror to tape" option? First time I've heard of it & intrigued!
;)
***Edit***
Answered my own question with a little research (or is it RTFM?!).

SnapMirror-To-Tape
For NetApp NAS file servers with SnapMirror software installed, the NetApp NAS NDMP iDataAgent can perform block level backups and restores of NetApp volumes, which can be significantly faster than traditional backups, particularly for volumes with a very large number of files. Review the following before performing this type of backup and restore:
Configuration:
Please contact your software provider for assistance configuring SnapMirror-To-Tape.
Backup:
* SnapMirror-To-Tape backups will back up snapshots along with the rest of the volume data.
* Only full backups of whole volumes can be performed.
* Backup Filters do not apply to SnapMirror-To-Tape backups; if filters are added, they are ignored.
* Since In-Place restore of SnapMirror-To-Tape backups of the root volume of a NetApp file server are not supported, we suggest you do not run SnapMirror-To-Tape backups of the root volume. While the root volume can actually be backed up via a SnapMirror-To-Tape backup, the root volume cannot be turned offline, and thus you cannot restore to it.
Browse:
* When browsing the data for a restore, the volume will be shown, but none of the contents of the volume; this is because only full restore of a whole volume is supported.
* The browse for a restore destination will not show any volumes that are in a restricted state; the restricted destination volume must be typed in the destination path field.
* There is no special indication that SnapMirror-To-Tape was used for a backup. The only indication will be that the browse of the backed up data will not show any contents of the backup, just the volume.
Restore:
* Only full restores of whole volumes can be performed; this replaces all existing content on the volume.
* The destination volume for restore must be in a "restricted" state (see your Network Appliance documentation on how to set a volume to a restricted state.)
* The restore destination must be the root of a volume, e.g., /vol/vol1.
* Restoring the volume out of place will create a NetApp mirror volume.
* Selecting the Direct Access Restore option will have no impact on the restore.
