Though many types of on-line backup services are in place, the kind of solution offered by Dropbox continues to enthral savvy netizens. Besides automatically uploading files/folders kept on a specified folder in the desktop on to its server, Dropbox can sync those files/folders across multiple machines too. Now, if your storage requirements exceed Dropbox's 2GB limit or you wish to have a ‘plan B', a Dropbox-type backup/syncing solution, take a look at the service offered by IDriveSync (http://www.IDriveSync.com/). This service allows you to store your files/folders on its server and transfer them automatically to multiple PCs (the storage space is limited to 2GB for free users). To use the service, you need to create an account. To help you easily download/upload/ the files/folders and sync/share them across multiple machines, IDriveSync provides a client-software too.
After installing the client, assign a desktop folder to it and log-in to the system. Once the IDriveSync setup is ready, you can simply forget about the backing up process. Whenever you wish to keep a file on-line, just place it on the IDrive folder — the IDriveSync client working in the background will come active and immediately transfer the file to its server. IDrivesync can be accessed via Windows Explorer too. This means you can upload any file/folder on your desktop by just right-clicking on it and selecting the ‘IDriveSync' option from the menu that pops-up.
Now, if you wish to transfer your files in the IDrive server to another PC, just install IDriveSync on the second PC and log-in to your account — the files from the server will start flowing to the IDrive folder of the new machine.
