This option can be quite slow, so only use it if you need it.

+is not used and the whole file is sent as-is instead. The transfer may be
+faster if this option is used when the bandwidth between the source and
+target machines is higher than the bandwidth to disk (especially when the
+"disk" is actually a networked file system). This is the default when both
+the source and target are on the local machine.
dit(bf(-p, --perms)) This option causes rsync to update the remote
permissions to be the same as the local permissions.
files at the destination will be automatically disabled. This is to
prevent temporary filesystem failures (such as NFS errors) on the
sending side causing a massive deletion of files on the

+destination. You can override this with the --ignore-errors option.
dit(bf(--delete-excluded)) In addition to deleting the files on the
receiving side that are not on the sending side, this tells rsync to also
the receiving filesystem. If you want to delete after transferring
then use the --delete-after switch.
+dit(bf(--ignore-errors)) Tells --delete to go ahead and delete files
+even when there are IO errors.
+
dit(bf(--force)) This options tells rsync to delete directories even if
they are not empty. This applies to both the --delete option and to
cases where rsync tries to copy a normal file but the destination
transferred on the receiving side. The default behavior is to create
the temporary files in the receiving directory.
-dit(bf(--compare-dest=DIR)) This option instructs rsync to use DIR as an
-additional directory to compare destination files against when doing
-transfers. This is useful for doing transfers to a new destination while
-leaving existing files intact, and then doing a flash-cutover when all
-files have been successfully transferred (for example by moving directories
-around and removing the old directory, although this requires also doing
-the transfer with -I to avoid skipping files that haven't changed). This
-option increases the usefulness of --partial because partially transferred
-files will remain in the new temporary destination until they have a chance
-to be completed. If DIR is a relative path, it is relative to the
-destination directory.

dit(bf(-z, --compress)) With this option, rsync compresses any data from
-the source file(s) which it sends to the destination machine. This
+the files that it sends to the destination machine. This
option is useful on slow links. The compression method used is the
same method that gzip uses.

+dit(bf(--write-batch)) Generate a set of files that can be transferred
+as a batch update.
