+dit(bf(-y, --fuzzy)) This option tells rsync that it should look for a
+basis file for any destination file that is missing.  The current algorithm
+looks in the same directory as the destination file for either a file that
+has an identical size and modified-time, or a similarly-named file.  If
+found, rsync uses the fuzzy basis file to try to speed up the transfer.

+Note that the use of the bf(--delete) option might get rid of any potential
+fuzzy-match files, so either use bf(--delete-after) or specify some
+filename exclusions if you need to prevent this.
