In an "incremental backup", files matched in the previous backup are
omitted altogether, right?  So then all you need to do is copy all the
files from /backupdir/back2 and /backupdir/back1 into one directory,
where files from /backupdir/back1 override those from
/backupdir/back2.  This is easy to do with rsync (or with cp, for that

rsync -a /backupdir/back2 /backupdir/increment
rsync -a /backupdir/back1 /backupdir/increment

Does this answer your question, or have I misunderstood it?
