BeinSync lets you backup your data and sync your PCs, among other things. Rather than emailing yourself files or loading them up on to your thumb drive, you could control all your files remotely using BeinSync. It’s much more straightforward and simple than sending files back and forth to your self. BeinSync automatically synchronizes your files, your email, your contacts and bookmarks on up to three PCs. What ever changes you make on one machine will automatically be changed on the others. You can access data from any one of your computers on the internet and sync with other BeinSync users too. Versions for single users and businesses are available starting at around $59 a month. BeinSync also works with SanDisk’s Cruzer flash drive, allowing users to insert their drive into any computer and backup all files online.
