Abstract
A microservice or serverless process consistency check process comprising locating all the necessary metadata and data objects in the cloud by storing the data objects in the cloud and synchronously mirroring the metadata, which is separately stored in local storage, to the cloud. The process generates a list of data objects in the cloud as “Set A” and the list of metadata objects in the same prefix range as the data objects as “Set B.” The consistency check then verifies whether all objects in Set A are referred to by objects in set B. In the case where there are gaps between the sets, non-existent objects are marked as missing, and unreferenced objects are marked as orphan objects. The list of missing and orphan objects is then sent back to the backup server for analysis and further processing.
