Subject: NDMP backup of snapmirror target

I am snapmirroring several volumes to a DR site, and I would like to do tape backups at that site.  How should I do them?  Can I use NDMP?

It seems like I can't do straight NDMP because the replicated target is read-only.  I am currently creating flexclones from snapshots existing in the volume (nightly.0...) but flexclone then locks this snapshot and snapmirror will fail to update  ( I'm not sure if this happens at the next update or when the source system attempts to remove that snapshot and copy it over... I wasn't watching).

What do you generally do to get snapmirrored volume data to tape?

TIA,

Fred
