I’ve been looking for a decent online backup solution for OS X, and I think I’ve found one in Mozy Online Backup. 2 Gigs of storage is free, and there’s a nice helper OSX app to download. It does also work for PC’s – give it a try. You DO backup offsite, don’t you? Edit: Mozy actually seems a little flaky, at least in its free incarnation – I often foun the client won’t connect. Now using some spare webspace and webdav to emulate .mac instead. Mozy is a nice try though….
