SpiderOak is a cross-platform, multi-computer online backup, centralization, and sharing system coded in Python and C. Capabilities include comprehensive "zero knowledge" encryption, space efficient preservation of historical versions of files, and access to files across all computers from any device. Backed up folders may be include in web "Share Rooms" for easy sharing/collaboration. Great emphasis is made towards triviality of installation and operation.

Version: SpiderOak Mac 3.7.97
Very resource friendly Fast uploading Keeps many versions of files Can be turned off if needed (will rescan directories)
Somewhat confusing to deselect files from being uploaded (you have to delete them from various places). Does a full system scan at startup, so is slow then,
I've been using Spideroak for a long while and am extremely pleased with it. It is more expensive than other services. However, it's light-years better than any other service I tried. Among other things, Spideroak manages their own services so that, unlike Mozy and others I tried, the uploading is fast! So it's not impossible, for example, to sync my (fairly large and frequently updated) music selection. Also, my computer suffers no noticeable performance difference when I run it... again, in stark contrast to its competitors.

I should note that I am using the PC version, not the Mac version, but that I couldn't find a PC version to review on CNet. I use Windows 7, 64-bit.
