Abstract: Methods and systems for reducing the data recovery time when failing back to a primary system from a secondary data backup system using virtual machine conversions and incremental exportation for backed-up virtual machine snapshots are described. Upon detection that the primary system is available to receive replicated snapshots for a virtual machine, the secondary data backup system may identify a first virtual machine snapshot out of a chain of snapshots for the virtual machine (e.g., the earliest in time snapshot within the chain or a middle snapshot in the middle of the chain) and transfer a full image snapshot for the first virtual machine snapshot to the primary system. Thereafter, data changes between the next virtual machine snapshot to be transferred to the primary system and the most-recently hydrated virtual machine on the primary system may be identified and then transferred to the primary system.
