Abstract

Described is a system (and method) for managing specialized metadata that may be used to manage and search incremental backup data stored on a cloud-based object storage. The system may create and store such metadata as part of a specialized metadata database that includes a data catalog and a backup catalog. The system may leverage the metadata database to initiate operations to efficiently manage incremental backup data stored on the object storage. For example, the metadata may be relied upon to efficiently reconstruct (e.g. synthetically) the client data to a point-in-time of any incremental backup. In addition, the metadata may include properties of the backed-up data, which are maintained separately from the backup data stored as objects. Accordingly, these properties may be searched to identify and locate backup data without having to retrieve the stored objects.
