Cloud-based air-gapped data storage management system

A method comprising:

• by a source data storage management system:
• backing up data generated by a data processing resource executing an application,
• extracting metadata from a management database of the data storage management system,
• generating a first backup copy comprising a supplemental metadata portion comprising the extracted metadata and a backup portion comprising the data in a backup format that is distinct from a primary data format generated by the application at the data processing resource, and
• storing the first backup copy to a cloud computing environment, wherein the first backup copy is governed by the source data management system;
• and
• by a destination data storage management system configured in the cloud computing environment:
• reading the first backup copy stored in the cloud computing environment,
• wherein the source data storage management system is distinct from and lacks information about the destination data storage management system,
• based on at least some of the supplemental metadata, recognizing that the first backup copy is compatible with the destination data storage management system,
• replicating the backup portion of the first backup copy generating a second backup copy by to generate a second backup copy without first restoring the data in the first backup copy, wherein the second backup copy is governed by the destination data storage management system and not by the source data storage management system, and
• restoring data in the second backup copy to primary data in the cloud computing environment, wherein the primary data is in the primary data format of the application, and wherein an application executing on a virtual machine in the cloud computing environment consumes the restored primary data.

A method comprising:

• by a destination data storage management system configured in a cloud computing environment:
• using an authentication technology to read at least part of supplemental metadata in a first backup copy that is stored in the cloud computing environment, wherein the first backup copy was generated and stored in the cloud computing environment by a source data storage management system that is distinct from and lacks information about the destination data storage management system, and wherein the backup copy comprises the supplemental metadata and a backup portion, wherein the backup portion comprises data backed up into a backup format by the source data storage management system;
• based on the at least part of the supplemental metadata, recognizing that the first backup copy is compatible with the destination data storage management system;
• generating a second backup copy by replicating at least the backup portion of the first backup copy, wherein the second backup copy comprises the data in the backup format;
• and
• storing the second backup copy to a data storage resource at the cloud computing environment, wherein the data storage resource is associated with the destination data storage management system, wherein the second backup copy is governed by preferences administered in the destination data storage management system, and wherein the first backup copy is governed by other preferences administered in the source data storage management system.
