dont get the problem, just put things in that folder that you want synced ??
But if you want to sync most of your documents, photos etc, then that's just a nightmare.
Found one after lots of reading up - Syncplicity
Very lightweight, costs me $9.99 a month for 50gb space, which i'll use nearly all of.
The application is very quick and small, you install, choose which folders you want to Sync, then it uploads in the background.
Add it to another computer (ie. my nc10) and it downloads them all in the background into the similar folders (ie. My Pictures)
When you open a document, change it and save it, it will automatically upload it to your online backup, and automatically download it to your second computer. For example - i wrote a letter on my PC, buggy came to pick me up. Saved the letter, grabbed my NC10, turned it on and had the letter (internet access dependant of course)
Considering i've got 8 years of photos on there that i've never backed up, i think this will be perfect for me.
All files also available to view and edit online, and if you edit, they get downloaded to your PC & laptop for example.
They also keep revision copies for a month, as well as deleted items
