Abstract:
A method and system for recovering a corrupt virtual disk is discussed. A request to recover the disk may be received. A recovery snapshot for the last point-in-time the system was stable may be synthesized. A difference may be identified between that recovery snapshot and the corrupt disk. A virtual machine may communicate with both the difference and the corrupt disk, and the difference may be merged with the corrupt disk.
