Abstract: In general, one aspect of the subject matter described in this specification can be embodied in methods that include receiving, at a computer system, a request to create a snapshot of a virtual storage device, wherein the virtual storage device virtually stores data at virtual addresses, the data being physically stored at a plurality of physical storage locations that are managed by an underlying storage system associated with virtual storage device. The methods can further include identifying, by the computer system, one or more regions of the virtual storage device that have been written to since a previous snapshot of the virtual storage device was created. The methods can additionally include generating a unique identifier for the requested snapshot; and creating the requested snapshot using the identified one more regions and the unique identifier.
