it works on my system, OS X 10.6.4.

i've used SuperDuper 2.6.2 for years, and i just started using Apple Backup 3.2 to back up data to my Mobile Me iDisk. the problem is that none of these solutions would find a hard drive i had connected to my Apple Airport Extreme Base Station. Also, none of the other solutions would backup data on a hard drive, specifically to a folder on another hard drive. i was really surprised to find out that none of these solutions had simple functions like that.

i hesitantly downloaded SilverKeeper because i don't trust LaCie products. i've had 4 LaCie d2 Quadra hard drives fail on me in less than a year, $800 down the drain. anyway, i took the chance cause of some good reviews i read, and i installed SilverKeeper and ran it. it was able to find my "Air Disk", and allowed me to choose a folder to backup to on another hard drive, not just a volume (i don't like partitioning my hard drives). now i can backup that hard drive as well without having to disconnect it from my Airport Extreme and connect it directly to my mac.

so far, so good. no crashes or problems. i'm happy for now :-)
