   rsync do compare a source and a destination and then copies the changes,   
   so if your destination directory change name all the time, rsync will   
   copy everything.

   btrfs has the ability to tell you what has changed between two snapshots.   
   Think you also can do this with zfs and maybe with the experimental   
   bcachefs.   
   Using lvm it could be possible too to diff the snapshot and the current   
   one, get a list of files and then just sync those.   
      
   I think you would need to start your session with a rsync -rvn, store   
   the output, when it's time to shut down you need to run rsync -rvn   
   again, store this output in another file, then you diff the two files to   
   see the difference, the files added you can then sync.
