Handling aborts of backup operations is described. A system receives an abort request message corresponding to a backup operation associated with a source storage device. The system determines whether a snapshot associated with the backup operation is created of the source storage device. The system synchronizes the source storage device with a target storage device in response to a determination that the snapshot associated with the backup operation is created of the source storage device. The system sends an abort completion message to a backup/restore application interface associated with the backup operation.
