| - | 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.
