Abstract
Techniques described herein relate to a method for performing backups of virtual machines on a host. The method includes obtaining an incremental image backup generation request associated with a virtual machine (VM) of the host; obtaining current file system metadata associated with the VM; obtaining previous backup metadata associated with the VM; generating updated file system metadata that includes status indicators associated with each file by comparing the current file system metadata with the previous backup metadata; obtaining a list of changed data blocks associated with the VM; writing changed data blocks associated with the VM to a backup storage; generating incremental backup metadata by associating portions of the updated file system metadata with each changed data block in the list of the changed data blocks; and writing the incremental backup metadata with the changed data blocks in the backup storage.
