Specialized metadata for managing and searching backup data stored on a cloud-based object storage

A method comprising:

• performing a backup of client data stored on a client device to a new set of objects stored on a cloud-based object storage, the client data including one or more data items each associated with one or more properties that are stored as part of the data item, the cloud-based object storage including existing objects associated with previous backups of existing client data;
• obtaining, for each of the data items, the associated properties;
• storing the associated properties as part of a set of entries within a data catalog, the associated properties for each data item stored as part of a corresponding entry that stores metadata of the data item;
• receiving a request to identify a first data item stored within the new set of objects, the request including a search value;
• searching the set of entries within the data catalog data using the search value;
• identifying a first entry, amongst the set of entries within the data catalog, corresponding to the first data item based on the search value matching the metadata stored by the first entry;
• and
• retrieving the first data item from a first object, amongst the new set of objects, based on the metadata stored by the first entry indicating the first data item is stored within the first object.

A computer program product comprising a non-transitory computer-readable medium having a computer-readable program code embodied therein to be executed by one or more processors, the program code including instructions to:

• perform a backup of client data stored on a client device to a new set of objects stored on a cloud-based object storage, the client data including one or more data items each associated with one or more properties that are stored as part of the data item, the cloud-based object storage including existing objects associated with previous backups of existing client data;
• obtain, for each of the data items, the associated properties;
• store the associated properties as part of a set of entries within a data catalog, the associated properties for each data item stored as part of a corresponding entry that stores metadata of the data item;
• receive a request to identify a first data item stored within the new set of objects, the request including a search value;
• search the set of entries within the data catalog data using the search value;
• identify a first entry, amongst the set of entries within the data catalog, corresponding to the first data item based on the search value matching the metadata stored by the first entry;
• and
• retrieve the first data item from a first object, amongst the new set of objects, based on the metadata stored by the first entry indicating the first data item is stored within the first object.
