While we generally recommend dedicating a disk for the backup, you can use a single disk to maintain a backup in addition to other data.

There are two methods of cloning offered by Casper. Casper can be instructed to clone the entire contents of one hard disk to another hard disk, or clone a specific partition/volume to another partition/volume. When using the Copy an entire hard disk method, Casper completely replaces the existing content of the destination device, master boot record, existing partition structure, etc. When using the Copy a specific drive method, Casper clones only the file system format and content of one partition/volume to another, but does not otherwise modify or replace any existing partition structure on the destination device.

With this in mind, you can use the Copy a specific drive option to create and maintain a backup in addition to “other data” on the backup hard disk.

To set up the backup hard disk, use the Copy an entire hard disk method to make the initial copy on the backup hard disk. When prompted by the Copy Drive Wizard to specify how the additional space on the hard disk is to be used, select the second option, Leave the additional space unallocated. Once this initial copy has been performed, use the Create Drive option to create one or more additional partitions on the backup hard disk for your “other data.”

At this point, you might want to change the volume label associated with the drive letter assigned to the backup of your system drive. For example, you might consider renaming this drive "System Backup." You can change the volume label of a drive by right-clicking on the drive in [My] Computer and selecting Rename.

To maintain the backup of your computer’s system drive, select the Copy a specific drive method and then select your computer’s system drive (e.g., “Local Disk (C:)”) as the source and the drive letter associated with the corresponding backup partition (e.g., “System Backup (E:)”) created on the backup hard disk as the destination. You also can setup a 1-Click Cloning shortcut to perform the backup on demand.

By using the Copy a specific drive method to maintain the backup of your computer’s system drive, any data located in any other partitions on the backup hard disk will be left intact.
