====== Rsync Reference ======

The windows implementation of rsync is called [[http://www.google.co.nz/search?q=cwrsync|cwrsync]].

===== Example batch file =====

<code dos>
@ECHO OFF

REM Make environment variable changes local to this batch file
SETLOCAL

REM ** CUSTOMIZE ** Specify where to find rsync and related files (C:\CWRSYNC)
SET CWRSYNCHOME=C:\Program Files (x86)\cwRsync

REM Set CYGWIN variable to 'nontsec'. That makes sure that permissions on your windows machine are not updated as a side effect of cygwin operations.
SET CYGWIN=nontsec

REM Set HOME variable to your windows home directory. That makes sure that ssh command creates known_hosts in a directory you have access.
SET HOME=%HOMEDRIVE%%HOMEPATH%

REM Make cwRsync home as a part of system PATH to find required DLLs
SET CWOLDPATH=%PATH%
SET PATH=%CWRSYNCHOME%\BIN;%PATH%

REM Windows paths may contain a colon (:) as a part of drive designation and backslashes (example c:\, g:\). However, in rsync syntax, a colon in a 
REM path means searching for a remote host. Solution: use absolute path 'a la unix', replace backslashes (\) with slashes (/) and put -/cygdrive/- 
REM in front of the drive letter:
REM 
REM Example : C:\WORK\* --> /cygdrive/c/work/*
REM 
REM Example 1 - rsync recursively to a unix server with an openssh server :
REM
REM       rsync -r /cygdrive/c/work/ remotehost:/home/user/work/
REM
REM Example 2 - Local rsync recursively 
REM
REM       rsync -r /cygdrive/c/work/ /cygdrive/d/work/doc/
REM
REM Example 3 - rsync to an rsync server recursively :
REM    (Double colons?? YES!!)
REM
REM       rsync -r /cygdrive/c/doc/ remotehost::module/doc
REM
REM Rsync is a very powerful tool. Please look at documentation for other options. 
REM

REM ** CUSTOMIZE ** Enter your rsync command(s) here
rsync -r -u --delete -v "/cygdrive/C/External Drives/Secondary Media/Mp3s" "/cygdrive/E"
</code>

===== Useful Options =====

| -r | Recursive |
| -u | Update files that need updating (rather than just copying everything) |
| <nowiki>--delete</nowiki> | Delete files in the destination that are not in the source. |
| -v | Verbose. More info, but not too much info. |
| -n | Test run. Don't actually do anything. |
