We just started testing with the patch, so I cant say much about it.
I know the backup process and I doubt the patch can temper with it. More
likely you lost what's missing in the backup with your initial sync and
did not recognise it at that time.

The backup is a collection of csv files, have you looked into it?
As it is line based, you should be able to use diff two (unpacked) files.
