You may move the data within your account in such a way that the file path in your account should mirror the file path on your local machine. You may create new folder with a different drive letter and machine name and move the backed up data to this new folders. You can do this by logging into your account at http://www.idrive.com
When you initiate a backup, our application will compare the data that is backed up to your account and the data from the new setup (new machine) and will perform an incremental backup if there are no changes in file name and file path.
