| - | An interesting article titled "DNS323 RSync Time Machine!" was posted [[http://forum.dsmg600.info/t2125-DNS-323-Rsync-Time-Machine%21.html|here]] on the DNS323 forum. The author, raid123, brought to light some very interesting information regarding use of RSync's hard links. Following implementation of such on my NAS I couldn't help but wonder if a similar approach could be used to backup data from three Windows based PC's located throughout the household. Following a brief search of the Internet I was pleased to see tools capable of assisting in this regard were available. | + | An interesting article titled "DNS323 RSync Time Machine!" was posted [[http://dns323.kood.org/forum/t2125-DNS-323-Rsync-Time-Machine%21.html|here]] on the DNS323 forum.

| - | Installation of a package known as Cygwin on all three Windows PC's is necessary. Cygwin provides an RSync client and allows creation of a symbolic link at the end of the backup process. As with raid123's approach for the "DNS323 RSync Time Machine!", a symbolic link named Current will take you to the latest backup directory. | + | Installation of a package known as Cygwin on all three Windows PC's is necessary.

| Following instruction found at [[http://www.gaztronics.net/rsync.php|Gaztronics.net]], install "RSync for Windows". Although the instruction indicates three key Cygwin modules are required, I found that by installing the Cygwin GNU core utilities module (coreutils/coreutils-6.10-1) symlinks could be built thus allowing creation of a link to the latest backup. | Following instruction found at [[http://www.gaztronics.net/rsync.php|Gaztronics.net]], install "RSync for Windows".

| In order for the RSync client on each PC to communicate with the DNS323, an RSync daemon needs to be running on the DNS323. Using Telnet or Putty access the DNS323 and set the execution bit of the rsyncd.sh file; chmod a+x /ffp/start/rsyncd.sh. Start the daemon by issuing an "/ffp/start/rsyncd.sh start" command. If all is well with your rsyncd.conf file the script should start with an indication of success. | In order for the RSync client on each PC to communicate with the DNS323, an RSync daemon needs to be running on the DNS323.
