I don't really know. I mean that files which have been used by snapshots are stored in a metadata file IIRC.

The question is more: "what do you exactly want to know"?

You have to understand that snapshot backups "shards" and not individual documents. So the difference you are looking after won't tell you which documents have been backup'ed on the second run.

Makes sense?
