We're big fans of both Syncplicity and SugarSync. These tools enable you to synchronise your files across multiple computers, irrespective of operating system. Install SugarSync on your desktop computer and choose the files you want to backup. These files (and folders) are backed up to a remote online account. You can then access these files on any computer, from a standard web browser and download to the computer (or restore back to the original computer), if you suffer from a system crash.
However, here's the neat part. Install SugarSync on your Mac-based laptop and you can keep files synchronised across both machines, via your online account. If you have some word files in your "My Documents" folder on your PC, you can make these download automatically to your "Documents" folders on your Mac. Edit the work on your Mac, save, then the files are synchronised back to your PC. Brilliant.
SugarSync 1.5 now goes one step further. Not only can you backup, synchronise and access these files from any location, you can also choose to share files and folders with other users. If you're just back from your latest vacation, grab your favourite photos, choose to share them with your friends and they'll be available to other users. This applies to work documents too. You can share files between your colleagues, whether you are working from a beach hut in Italy or a remote office in northern Norway. The files will be available to share with other users and, if you want, you can enable them to make changes. If someone makes a change, the file will then be synchronised back to your laptop when you log back in to your account.
