Abstract: An illustrative cloud-based air-gapped data storage management (destination) system obtains authorized access to other (source) systems' backup copies, replicates those copies within the destination system, parses supplemental metadata included in the source backup copies, and integrates the replica copies into the destination system as though natively created there. Replica copies are integrated as backup copies without first restoring the source backup copies to a native data format. The source system lacks knowledge of or connectivity with the destination system, thus maintaining an “air gap” between the systems. The destination system preferably operates in a cloud computing environment. The destination system uses supplemental metadata from the replica copies to re-create or mimic the source's computing environment and to restore backed up data from the replica copies. The destination system also operates as an autonomous analytics engine, applying value-added services to backed up data pulled from source system(s).

Abstract: Systems and methods are provided herein for automatically configuring newly installed secondary storage computing devices and managing secondary storage computing devices when one or more become unavailable. For example, a storage manager can then detect the computing resources available to the newly installed secondary storage computing device, assign a role to the newly installed secondary storage computing device based on the detected computing resources, configure the newly installed secondary storage computing device with deduplication and storage policies used by the other secondary storage computing devices, re-partition secondary storage devices to allocate memory for the newly installed secondary storage computing device, and instruct other secondary storage computing devices to replicate their managed data such that the newly installed secondary storage computing device has access to the replicated data.

Abstract: An information management system according to certain aspects may determine whether storage operations will execute properly prior to executing them in a cloud services environment. The system may check various factors or parameters relating to a storage policy to verify whether the storage policy will work at runtime without actually executing the policy. Some examples of factors can include: availability of primary storage devices, availability of secondary storage devices, license availability for performing that operation, user credentials for connecting to primary and/or second storage devices, available storage capacity, connectivity to storage devices, etc. The system may also check whether a particular system configuration is supported in connection with storage operations. The result of the determination can be provided in the form of a report summarizing any problems found with the storage policy. The report can include recommended courses of action or solutions for resolving any identified issues.

Abstract: Techniques disclosed herein are well suited to restoring deduplicated backup data from cloud-based storage and from multi-node replicated files systems, and they also improve performance in more traditional data storage technologies. Pre-restore steps include analysis of deduplication indexes to identify data segments that are stored consecutively on storage media. Reading data in aggregate runs of consecutively stored data segments reduces interactions with storage media that hosts the deduplicated data and speeds up retrieval. Parallel reads from multiple storage devices in multi-node replicated file systems also speed up retrieval. An illustrative enhanced media agent pre-fetches data (stored in deduplicated form) in anticipation of read requests that are expected in the restore operation. The pre-fetched data is temporarily stored locally at the media agent, which is responsible for interfacing with storage media and is further responsible for orchestrating the disclosed techniques within an illustrative data storage management system.

Abstract: An improved information management system that implements a staging area or cache to temporarily store primary data in a native format before the primary data is converted into secondary copies in a secondary format is described herein. For example, the improved information management system can include various media agents that each include one or more high speed drives. When a client computing device provides primary data for conversion into secondary copies, the primary data can initially be stored in the native format in the high speed drive(s). If the client computing device then submits a request for the primary data, the media agent can simply retrieve the primary data from the high speed drive(s) and transmit the primary data to the client computing device. Because the primary data is already in the native format, no conversion operations are performed by the media agent, thereby reducing the restore delay.

Abstract: If a deduplication database becomes corrupted or is lost, the deduplication database may be reconstructed by restoring an earlier backup copy of the deduplication database. The backup copy of the deduplication database, however, may not be synced with the deduplicated data blocks that are presently stored in the secondary storage subsystem. To address the possibility of data loss and improve reconstruction timing, a deduplicated storage system is provided according to certain embodiments that uses one or more mechanisms to restore the deduplication database and resync with the secondary storage by using one or more journal files that track the data blocks that have been or may have been deleted from the secondary storage since the last deduplication database backup.

Abstract: According to certain aspects, a method can include receiving an indication that a restoration of a deduplication database using a secondary copy of a file associated with a secondary copy job is complete; retrieving a first data fingerprint from a data storage database, wherein the first data fingerprint is associated with the secondary copy job used to restore the deduplication database; retrieving a second data fingerprint from a deduplication database media agent, wherein the second data fingerprint is associated with the secondary copy job used to restore the deduplication database; comparing the first data fingerprint with the second data fingerprint to determine whether the first data fingerprint and the second data fingerprint match; and transmitting an instruction to the deduplication database media agent to rebuild the restored deduplication database in response to a determination that the first data fingerprint and the second data fingerprint do not match.

Abstract: According to certain aspects, an information management cell can include at least one secondary storage computing device configured to conduct primary data generated by at least one client computing device to a secondary storage device(s) as part of secondary copy operations, wherein the secondary storage computing device normally operates to conduct primary data to the secondary storage device(s) for storage as a secondary copy in a first secondary copy file format, at the direction of a main storage manager; and can include a failover storage manager configured to activate in response to loss of connectivity between the cell and the main storage manager, and instruct a secondary copy application to perform a secondary copy operation in which the primary data generated by the at least one client computing device is stored as a secondary copy in a second secondary copy file format different than the first secondary copy file format.
