What PDAs Blog shares about SugarSync:

I’ve got good news for users who need to synchronize data between their PC, Mac, and mobile device: SugarSync is now offering a FREE account with up to 2GB storage. SugarSync lets to back up, access, and share your files from Mac, PC and mobile devices.

It offers multi-system, cross-platform syncing along with file explorer integration, web access with sharing, and photo gallery features. SugarSync offers clients for Windows Mobile gadgets like BlackBerry and the iPhone. The free accounts include access to mobile clients.

Although the free storage won’t let you back up all of your music files, 2GB will go a long way with simple documents and files. There are other competing services on the market, but SugarSync is different in that it lets you add folders anywhere on your system that will be synchronized. In addition, SugarSync’s free account limits you to syncing with 2 computers. Other offerings (some of which are paid services) do not have this limitation.
