transferred on the receiving side. The default behavior is to create
the temporary files in the receiving directory.
+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.

dit(bf(--compare-dest=DIR)) This option instructs rsync to use em(DIR) on
the destination machine as an additional hierarchy to compare destination
files against doing transfers (if the files are missing in the destination
(or implied by bf(-a)). You can work-around this bug by avoiding the bf(-o) option
when sending to an old rsync.
-dit(bf(-z, --compress)) With this option, rsync compresses any data from
-the files that it sends to the destination machine. This
-option is useful on slow connections. The compression method used is the
-same method that gzip uses.
+dit(bf(-z, --compress)) With this option, rsync compresses the file data
+as it is sent to the destination machine, which reduces the amount of data
+being transmitted -- something that is useful over a slow connection.
-Note this this option typically achieves better compression ratios
-that can be achieved by using a compressing remote shell, or a
-compressing transport, as it takes advantage of the implicit
-information sent for matching data blocks.
+Note this this option typically achieves better compression ratios that can
+be achieved by using a compressing remote shell or a compressing transport
+because it takes advantage of the implicit information in the matching data
+blocks that are not explicitly sent over the connection.
dit(bf(--numeric-ids)) With this option rsync will transfer numeric group
and user IDs rather than using user and group names and mapping them
