There is a feature in rsync that makes snapshots easy. This feature is a simple option called link-dest. What it does is compare the source path you want to copy from with that of the original backup path. It then copies any new or changed files from the source to a second defined backup path. Rsync creates hard links to any none changed files/directories under the second defined backup path. This essentially gives you two snapshots of the original source… text/html 2009-01-08T14:10:38-07:00 David Miller http://www.sdmachelp.com/wiki/doku.php/mac/mac-howto/rsync3?rev=1231449038&do=diff HOWTO compile rsync version 3.x and get a universal binary that will run on 10.4.x and 10.5.x. Note: You will need a PPC and Intel based mac running 10.4.x and the developer tools installed. On the PPC Mac Download both the rsync source(rysnc-3.x.x.tar.gz) and patches (rsync-patches-3.x.x.tar.gz ) from <http://www.rsync.samba.org>. Once you have the files open up the terminal and move into the same directory you downloaded the files to.

For example Notice that directories are colored blue and some files are colored green. This can be quite annoying depending on the color scheme of the terminal app you are using.
