SYSTEM AND METHOD FOR EFFICIENT BACKUP SYSTEM AWARE DIRECT DATA MIGRATION BETWEEN CLOUD STORAGES

摘要

A first cloud vendor is registered by a backup application. A file is moved from backup storage of the backup application to the first cloud vendor. A reference is maintained at the backup storage to the first file residing at the first cloud vendor. A second cloud vendor is registered by the backup application. The backup application directs a migration of the file from the first cloud vendor to the second cloud vendor without recalling the file to the backup storage. A reference maintained at the backup storage is updated to refer to the file now residing at the second cloud vendor. The updated reference is maintained at the backup storage.
