I've been trying some new online backup services lately. I will give a more complete report soon after I get a few projects done. All of these have a "free" option and are Mac & PC compatible. I don't think you can go wrong with any of these, so give them try.
ZumoDrive. 2GB free after you go through a few steps. It has a really great interface. Primarily designed for sharing media files (photos, music, etc) among your own devices, it works with any type of file. You can make folders and files shareable by giving a link to someone. Very similar to DropBox in that sense. Update: I'm really liking ZumoDrive... my 2nd favorite next to DropBox.
SpiderOak. 2GB free. Strange name, but it has a very slick interface, one of the better looking that I have seen. You can backup specific folders.
iDrive. 2GB free. iDrive has a great interface, and works really well. But they are a marketing machine... I have been getting all kinds of emails from them trying to sell me more stuff. They have another product called iDriveSync that sounds just like DropBox, but it is a PC-only solution. I am hoping they will come out with a Mac version soon.
Windows Live Mesh interface
Windows Live Mesh (formerly WIndows Live Sync) Windows Live SkyDrive. As a Mac-user, I am loathe to try anything Windows-related. But Microsoft has made the effort to create a file sharing service for Macs, so I decided to try it out. I have to admit their product offering is confusing. They have something called SkyDrive, Windows Live Sync, Windows Live Mesh. Oh, and you will need a Live.com account to use this service. The best thing about SkyDrive is that you get 25GB of online storage.
