Using some free online backup services including

Mozy offers free online 2GB backup and a downloadable tool to locate media and documents and keep them synchronized (i.e. the most current version uploaded to backup).

I've opted for the unlimited space US$4.95/month (charged in one 24 month block -beware I didnt see an option for a lesser term) and use it as a file server - but it's a damn cheap option either for backing up your computer against collapse or as a temporary location while you upgrade or reformat a pc .

Or just as a remote file location for sharing files with colleagues as I use it.

Update - got sent a link from a friend about Mozy. Apparently their restore functionality is
pretty iffy and users got left with weeks of calls and failed downloads or restores and some gave up completely
Bad Mozy swat !.

I am just using Mozy as a file server so it shouldn't affect me - but I must admit I wasnt impressed when signing up for the paid (pro) option they signed me up for two years.
When I complained I hadnt seen any options they said they would move me back to monthly and I must have missed the payment selections . I dont miss much on a web interface so they must have put the options somewhere obscure or preselected the most expensive option.

On the same subject I am using the free Dropbox service to synchronize 2Gig online for free also - this service is flawless but their volume option is twice as expensive as Mozy. But they are a pure file synchronization / backup service that just works.
