    Abstract: In certain systems disclosed herein, a distributed data monitoring and management system is provided that can replicate a distributed storage environment. The distributed data monitoring and management system can intelligently and automatically configure data access nodes to form a structure that matches the distributed storage environment. By matching the structure of the distributed storage environment, the distributed structure of the data may be maintained, enabling the data to be backed up from and/or restored to the distributed storage environment and/or migrated to another distributed storage environment without altering the distribution of the data. Further, embodiments herein enable the transfer of data from a non-distributed environment to a distributed storage environment. Thus, in some cases, an entity can migrate data from a local storage structure to a network-based distributed storage structure.

    Abstract: An information management system implements a method for determining whether to initiate a failover of a storage manager in the system. Nodes in the system may be assigned as monitoring nodes configured to communicate with a storage manager. Furthermore, each monitoring node may be configured to transmit a status inquiry message to each other monitoring node, and each monitoring node may receive a status inquiry message from each other monitoring node. Each monitoring node may also generate a session message comprising status information, and a plurality of failover nodes may receive the generated session messages. A failover node may then determine whether a failover condition has occurred by applying a plurality of failover rules to the status information of the transmitted session message. Where the failover node determines that a failover condition has occurred, the failover node may activate another storage manager to take place of the presently assigned storage manager.

    Abstract: Embodiments disclosed herein address the need to more efficiently backup a network-based storage environment that may be remote from a primary storage environment. For example, embodiments herein can provide a more efficient backup of a storage managed by a third-party entity. To improve the backup process, embodiments herein may optimize the number of scanning threads that are used to identify files that are to be backed up by, for example, analyzing the characteristics of the network and/or the network storage system to determine a number of scanning threads that will enable faster scanning of the network storage system while at the same time not overburden or be slowed down by a network between the network-based storage environment and the primary storage environment.

    Abstract: Certain embodiments disclosed herein reduce or eliminate a communication bottleneck at the storage manager by reducing communication with the storage manager while maintaining functionality of an information management system. In some implementations, operations performed as part of a backup process may be stored in transaction logs. These transaction logs may include information about a transaction performed between the client computing system and the network storage that hosts the backup of the client computing system. The transaction logs may be provided to a secondary storage system that can be used to form a backup index. The backup index may be used to facilitate accessing the data stored at the network storage. Advantageously, generating the transaction logs and separating the generation of the backup index from the backup process can reduce resource usage during performance of the backup and speed up the backup process while further reducing interaction with the storage manager.
