For the illiterates like myself, what does that mean?
I probably have about 10 gig of space currently for word files and PDFs.
It means that for cloud storage you need several pieces:
1. The cloud storage itself.
2. The app that runs on your computer(s) that backs up your data to the cloud.
3. The bandwidth that connects #1 and #2 above.
Amazon S2 gives you #1. You have to find #2 yourself. This should not be hard to do - I know the answer for linux. Not sure for windows.
(Note that carbonite is in the business of supplying #1 and #2 together, a convenience for which they are able to charge a premium).
Microsoft’s Sky Drive is free and provides 25 GB.
