Not addressing the wedge problem directly, but if you use
rdiff-backup or even rsync your backups will likely be much shorter and
the chance for a wedge may be reduced.
ie
rsync --delete -aH /u /y /var /b
or
for i in /u /y /var
do
rdiff-backup $i /b/$i
done
NB the slight difference of meaning of the destination directory.
I prefer rdiff-backup as I keep incrementals for very little disk
additional space.
