Hi
1) Would be a good option, as BE-2010 has NDMP support builtin to the product. Make sure to have the volume language appended with .UTF-8 to be able to guarantee the restore of characters out-of-bound of the standard US character set. (like ä,ö,ü etc)
2) Is also possible, but would end in Full-Backups, beacuse the snapshot is read-only and BE-2010 woud not be able to reset the archive bit.
I'd prefer Option 1.
