I suppose, this happens when you unpack some zip archive or similar?

This is actually a problem which cannot be solved if you use smb as the
transfer method. Incremental backups work by transferring only files
whose last modification time is younger than x. If you unpack an archive, the
last modification time is restored as well, so the incremental backup
will not consider the file as new.

Only rsync-based transfers are able to detect such changes because they
build and compare a file list on the server and client.
