An illustrative air-gapped data storage site for storing secure copies at the air-gapped storage site. Using specialized air-gapped media agents installed within the air-gapped storage pool site, the illustrative system, at an unpredictable time, establishes a one-way tunnel from secondary storage site to air-gapped site to receive backup copies of the data stored at primary site. In another embodiment, during disaster recovery, backup copies stored within the air-gapped site are replicated to a non-air gapped site (e.g., secondary storage pools) as 'tertiary copies.' Those copies are then restored to the primary site in original application data formats for quick recovery. As restoration of data is complete, the tertiary copies are promoted to “secondary copies” to receive incremental backups.

Secure data replication to, and recovery of data from, air-gapped data storage pools

A secure data storage management 'recovery system' operates in a cloud computing environment that is apart from a source system and source data being protected. A “recovery manager” in the cloud computing environment is responsible for restoring secondary copies that were generated by the source system. The recovery manager gains knowledge (metadata) about the secondary copies by restoring, for its own use, a management database of, and backed up by, the source system. The recovery manager initiates out-of-place restores of the secondary copies to “recovery clients” in the recovery cloud. The recovery system restores, to the recovery cloud, secondary copies from any cloud platform and/or from non-cloud data centers, including secondary copies stored locally, off-cloud by the source system. The recovery manager comprises new features that enforce its isolation from the source system and they act to protect the integrity of the secondary copies generated by the source system.

Cloud-based secure operation of a recovery storage manager

A data storage management system is enhanced to accommodate, and moreover to optimize, the storing and retention of deduplicated secondary copies at write-once read-many (WORM) enabled storage platforms. Enhancements include without limitation: user interface (UI) options to enable WORM functionality for secondary storage, whether used for deduplicated or non-deduplicated secondary copies; enhancements to secondary copy (e.g., deduplication copy, backup) operations; and pruning changes. The storage manager is generally responsible for managing the creation, tracking, and deletion of secondary copies, with and without deduplication. Media agents that store secondary copies to and prune them from the WORM-enabled storage platforms also are enhanced for communicating and interoperating with both bucket-level and object-level WORM-enabled storage platforms to implement the features disclosed herein.

Optimizing retention timeframes of deduplicated copies at storage platforms that are write-once read-many (WORM) enabled

Systems and methods for optimizing storage and retention of deduplicated secondary copies at storage platforms that are write-once read-many (WORM) enabled

As the volume of data under management expands rapidly, so do the costs associated with storing and that data on secondary storage devices. The illustrative approach provides an improvement to the information management system by delaying certain tasks that meet a set of criteria until a specified threshold is met. The system receives a request to be performed on a set of data stored on secondary devices. Power management module determines whether the task satisfies a set of criteria for delayed execution, queues the task, and when a specified threshold of the queued tasks is met powers up the necessary components to execute the tasks.
