Abstract:
According to certain aspects, a system includes a client device that includes a virtual machine (VM) executed by a hypervisor, a driver located within the hypervisor, and a data agent. The VM may include a virtual hard disk file and a change block bitmap file. The driver may intercept a first write operation generated by the VM to store data in a first sector, determine an identity of the first sector based on the intercepted write operation, determine an entry in the change block bitmap file that corresponds with the first sector, and modify the entry in the change block bitmap file to indicate that data in the first sector has changed. The data agent may generate an incremental backup of the VM based on the change block bitmap file in response to an instruction from a storage manager, where the incremental backup includes the data in the first sector.

Claim (Index 25):
A method of backing up a virtual machine, the method comprising:\n intercepting a first write operation generated by a virtual machine (VM) to store data in a first sector of a virtual hard disk, wherein the VM is executed by the hypervisor, wherein the VM comprises a virtual hard disk file and a change block bitmap file, and wherein the virtual hard disk file stores data associated with the virtual hard disk; and with a client computing device,\n determining that changes to the virtual hard disk are not reflected in the change block bitmap file, and, in response to the determination, invalidating the change block bitmap file and performing a full backup of the VM; \n determining an identity of the first sector based on the intercepted write operation; \n determining an entry in the change block bitmap file that corresponds with the first sector; and \n modifying the entry in the change block bitmap file to indicate that data in the first sector has changed.
