To ensure that cloned or image disks remain secure and are not accessible by others, there is a requirement to have these stored on encrypted drives.
When attempting to use tools such as Macrium Reflect, Acronis, O&O Software, there doesn't appear to be an option to mount an encrypted volume.
The primary tool of choice is O&O DiskImage as it supports cloning or imaging disks that are encrypted via BitLocker.
Since disks are often cloned or image in locations with no network connectivity, the only option is to use encrypted external hard drives. The devices are booted using a bootable CD as this negates the need to install the software e.g. O&O DiskImage.
How can disks be imaged or cloned to encrypted external drives?
