A backup image generator can create a primary image and periodic delta images of all or part of a primary server (101) The images can be sent to a network attached storage device (102) and a remote storage server (103) In the event of a failure of the primary server, the failure can be diagnosed to develop a recovery strategy Based on the diagnose, at least one delta image may be applied to a copy of the primary image to generate an updated primary image at either the network attached storage or the remote storage server The updated primary image may be converted to a virtual server in a physical to virtual conversion at either the network attached storage device or remote storage server and users may be redirected to the virtual server The updated primary image may also be restored to the primary server in a virtual to physical conversion As a result, the primary data storage may be timely backed-up, recovered and restored with the possibility of providing server and business continuity in the event of a failure |
