Right, you could end up with newer data mixed in with your backed up version which is probably not what you want. > Also, is it best to flush_binary (which I think flushes in memory > tables to disk), and compact prior to snapshotting? flush_binary only acts on the binary memtables.

Compaction isn't necessary and would slow down snapshotting considerably. -Jonathan
