Abstract

See full text

Aspects of the present invention provide a solution for creating a snapshot of a virtual server. In an embodiment, a first write storage is created in response to a snapshot request. For each write from the virtual server to primary storage that is the first write of that particular data block since the snapshot request, the data that resided in the data block previous to the write is copied from the primary storage to the first write storage.
