Abstract
A technique deploys a copy of a disk image from source storage to target storage. The technique involves identifying a particular disk image to be copied from the source storage to the target storage. The technique further involves performing a comparison operation between a first disk image list which lists disk images on the source storage and a second disk image list which lists disk images on the target storage to generate a common disk image list which lists a set of common disk images on both the source and target storage. The technique further involves transferring, from the source storage to the target storage, a set of data portions representing differences between the particular disk image and a common disk image listed on the common disk image list. The set of data portions in combination with the common disk image form a deployed copy on the target storage.
