NSF files are a proprietary database format used by Lotus Notes and
Domino, very complex, there's a pile of versions, and they are totally
opaque. Pretty sure that if they are being accessed or updated while
being copied the copy is invalid, so yes, some form of snapshotting is
required.
commercial backup software uses Domino/Notes APIs to do incremental
backups, for example
