1. A computerized method of backing up data to a replication target such that the data is recoverable from the replication target when a source application and one or more other intermediary replication targets are unavailable, the method being executed by a processor in communication with memory storing instructions configured to cause the processor to:
receive, at a first intermediary copy data management system, a first deduplicated data object associated with an application, the first deduplicated data object:
being replicated from a source copy data management system protecting the application, the first deduplicated data object generated based on a first deduplicated image associated with the application; andbeing received based on a first schedule, the first schedule defining a first set of times associated with replicating the first deduplicated data object from the source copy data management system to the first intermediary copy data management system, wherein the first deduplicated image is associated with one of:
changes in application data from a first snapshot associated with a backup of the application at a first time and a second snapshot associated with a backup of the application at a second point in time subsequent to the first time, anda full backup of the application; create, at the first intermediary copy data management system, a second deduplicated image associated with:
the first deduplicated data object when the first intermediary copy data management system does not have an existing data object comprising the first deduplicated object, andone of the first sets of time, the one of the first sets of time associated with a scheduled replication of the first deduplicated object; and replicate, at the first intermediary copy data management system, the first deduplicated data object to generate at least one of a second deduplicated data object and a third deduplicated image at a second copy data management system, the second deduplicated data object and the third deduplicated image being generated based on the second deduplicated image and according to a second schedule, the second schedule defining a second set of times associated with replicating the second deduplicated data object from the first intermediary data management system to the second copy data management system, the third deduplicated object associated with:
the second deduplicated data object when the second copy data management system does not have an existing data object comprising the second deduplicated object, andone of the second set of times, the one of the second sets of time associated with a scheduled replication of the second deduplicated object, thereby backing up data to a replication target such that the data is recoverable from the replication target when the source application and one or more other intermediary replication targets are unavailable. |
