Abstract
Methods, apparatus, and processor-readable storage media for efficient synchronization of a cloud enabled file system database during a snapshot restore operation are provided herein. An example computer-implemented method includes intercepting a user request to initiate a snapshot restore operation on a file system associated with a local storage system, wherein the file system comprises one or more stub files that are indicative of locations of cloud objects comprising files that were previously sent from the local storage system to a cloud storage platform; prior to the snapshot restore operation being performed, creating a current snapshot of the file system; obtaining an indication that the file system was successfully restored on the local storage system; and using the current snapshot to perform a synchronization operation, wherein the synchronization operation deletes one or more orphan cloud objects in the cloud storage platform that resulted from the snapshot restore operation.
