I am sure my ISP must think I'm into downloading films as the last couple of days have seen gigabytes of downloads for the Mac. The Apple Xcode development system (free!) isn't installed by default but it's a mere 1.25 GB download and the documentation set adds another 0.5GB. Tonight I installed the Subversion server and client. Working with a Version Control system does make keeping control of all the assets, source code and resources far simpler.
The fact that it was on the Mac isn't really important. I could have installed the Subversion server on my Linux box or preferably on my Windows box as I have a paid automatic backup to web system running there. I came close to losing 8 years of digital photos and other work when a hard disk motor failed thanks to the 'perfect storm' of an overloaded power supply that wrecked the hard disk motor and the loss of 25GB of backed up files when I reinstalled their backup software following a crash. Now I also keep an external hard disk backup as well. Paranoid? Maybe but if it prevents a total data loss...
Haha.. you need to be paranoid. MY 300GB HDD just crashed and to my luck, I backed up all 250GB except 25 GB and thats gone! (Yup it was near full)
