The rsync remote-update protocol allows rsync to transfer just the
-differences between two sets of files across the network link, using
+differences between two sets of files across the network connection, using
an efficient checksum-search algorithm described in the technical
report that accompanies this package.
NOTE: rsync's argument parsing expects the trailing ".", so make sure
that it's there. If you want to use a rsyncd.conf(5)-style
configuration file other than the default, you can added a
---config-file option to the em(command):

To synchronize my samba source trees I use the following Makefile

this allows me to sync with a CVS directory at the other end of the
-link. I then do cvs operations on the remote machine, which saves a
+connection. I then do cvs operations on the remote machine, which saves a
lot of time as the remote cvs protocol isn't very efficient.
I mirror a directory between my "old" and "new" ftp sites with the
the timestamps as being equal if they are within the value of
modify_window. This is normally zero, but you may find it useful to
set this to a larger value in some situations. In particular, when

dit(bf(-c, --checksum)) This forces the sender to checksum all files using
a 128-bit MD4 checksum before transfer. The checksum is then
.cvsignore file and matches one of the patterns listed therein. See
the bf(cvs(1)) manual for more information.
-dit(bf(--csum-length=LENGTH)) By default the primary checksum used in
-rsync is a very strong 16 byte MD4 checksum. In most cases you will
-find that a truncated version of this checksum is quite efficient, and
-this will decrease the size of the checksum data sent over the link,
-making things faster.
-
-You can choose the number of bytes in the truncated checksum using the
---csum-length option. Any value less than or equal to 16 is valid.
-
-Note that if you use this option then you run the risk of ending up
-with an incorrect target file. The risk with a value of 16 is
-microscopic and can be safely ignored (the universe will probably end
-before it fails) but with smaller values the risk is higher.
-
-Current versions of rsync actually use an adaptive algorithm for the
-checksum length by default, using a 16 byte file checksum to determine
-if a 2nd pass is required with a longer block checksum. Only use this
-option if you have read the source code and know what you are doing.

dit(bf(-T, --temp-dir=DIR)) This option instructs rsync to use DIR as a
scratch directory when creating temporary copies of the files
transferred on the receiving side. The default behavior is to create
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 links. The compression method used is the
+option is useful on slow connections. The compression method used is the
same method that gzip uses.
Note this this option typically achieves better compression ratios
