Abstract
A method, system, and computer-readable storage medium for managing backup operations of virtual machines are provided. According to one embodiment, a backup application initiates a snapshot of a storage volume, which stores a collection of virtual hard disk drives. A collection of virtual machines access the collection of virtual hard disk drives. The backup application accesses a collection of lists of changes to data. The collection of lists and the data are stored in the collection of virtual hard disk drives. A first list among the collection of lists is generated by a first virtual machine. The changes to data are made by the collection of virtual machines. The backup application generates an incremental backup of the first virtual hard disk drive by copying data from the snapshot in response to the first list identifying that the data changed subsequent to the generation of the prior backup.
