--backup-dir make backups into this directory

-u, --update update only (don't overwrite newer files)
+ -K, --keep-dirlinks treat symlinked dir on receiver as dir
-l, --links copy symlinks as symlinks
-L, --copy-links copy the referent of all symlinks
--copy-unsafe-links copy the referent of "unsafe" symlinks
--bwlimit=KBPS limit I/O bandwidth, KBytes per second
--write-batch=PREFIX write batch fileset starting with PREFIX
--read-batch=PREFIX read batch fileset starting with PREFIX

regardless of the timestamps. This might change in the future (feel
free to comment on this on the mailing list if you have an opinion).
+dit(bf(-K, --keep-dirlinks)) On the receiving side, if a symlink is
+pointing to a directory, it will be treated as matching a directory
+from the sender.
+
dit(bf(-l, --links)) When symlinks are encountered, recreate the
symlink on the destination.
is only relevant without --delete because deletions are now done depth-first.
Requires the --recursive option (which is implied by -a) to have any effect.
-dit(bf(-B , --block-size=BLOCKSIZE)) This controls the block size used in
+dit(bf(-B, --block-size=BLOCKSIZE)) This controls the block size used in
the rsync algorithm. See the technical report for details.
dit(bf(-e, --rsh=COMMAND)) This option allows you to choose an alternative
using the fileset whose filenames start with PREFIX. See the "BATCH
MODE" section for details.
+dit(bf(-4, --ipv4) or bf(-6, --ipv6)) Tells rsync to prefer IPv4/IPv6
+when creating sockets. This only affects sockets that rsync has direct
+control over, such as the outgoing socket when directly contacting an
+rsync daemon, or the incoming sockets that an rsync daemon uses to
+listen for connections. One of these options may be required in older
+versions of Linux to work around an IPv6 bug in the kernel (if you see
+an "address already in use" error when nothing else is using the port,
+try specifying --ipv6 or --ipv4 when starting the daemon).
+
+dit(bf(--checksum-seed=NUM)) Set the MD4 checksum seed to the integer
+NUM. This 4 byte checksum seed is included in each block and file
+MD4 checksum calculation. By default the checksum seed is generated
+by the server and defaults to the current time(), or 32761 if
+bf(--write-batch) or bf(--read-batch) are specified. This option
+is used to set a specific checksum seed, which is useful for
+applications that want repeatable block and file checksums, or
+in the case where the user wants a more random checksum seed.
+Note that setting NUM to 0 causes rsync to use the default of time()
+for checksum seed. Note also that bf(--write-batch) and bf(--read-batch)
+set the checksum seed to 32761, so bf(--checksum-seed=NUM) needs to
+follow these options if you want to specify a different checksum
+seed in batch mode.
