A stand-alone, network accessible data storage device, such as a filer or NAS device, is capable of transferring data objects based on portions of the data objects. The device transfers portions of files, folders, and other data objects from a data store within the device to external secondary storage based on certain criteria, such as time-based criteria, age-based criteria, and so on. A portion may be one or more blocks of a data object, or one or more chunks of a data object, or other segments that combine to form or store a data object. For example, the device identifies one or more blocks of a data object that satisfy a certain criteria, and migrates the identified blocks to external storage, thereby freeing up storage space within the device. The device may determine that a certain number of blocks of a file have not been modified or called by a file system in a certain time period, and migrate these blocks to secondary storage.

Data transfer techniques within data storage devices, such as network attached storage performing data migration

The systems and methods herein permit storage systems to correctly perform data recovery, such as direct access recovery, of Network Data Management Protocol (“NDMP”) backup data that was modified prior to being stored in secondary storage media, such as tape. For example, as described in greater detail herein, the systems and methods may permit NDMP backup data to be encrypted, compressed, deduplicated, and/or otherwise modified prior to storage. The systems and methods herein also permit a user to perform a precautionary snapshot of the current state of data (e.g., primary data) prior to reverting data to a previous state using point-in-time data.

Data recovery operations, such as recovery from modified network data management protocol data

A method and system for providing information management of mobile device data provides a user interface to permit a user of an information management system to define information management policies for the mobile device, receives definitions of the information management policies from the provided interface, and sends data from the mobile device to the information management system in accordance with the information management policies. In some examples, the system sends information identifying the user and the mobile device to the information management system, and/or sends the information management policies defined from the interface to the information management system.

Information management of mobile device data

Systems and methods for restoring a database in an information management system that does not include a secondary copy of the database, are disclosed. The systems and methods may include using metadata stored in non-production storage devices to restore the database. In some implementations the methods are used to consolidate multiple information management systems. In other implementations, the systems and methods are used for reviewing content of archived storage media. Other implementations are disclosed.

Restoration of centralized data storage manager, such as data storage manager in a hierarchical data storage system

For efficient high availability for a multi-node cluster using a processor device in a computing environment, using duplicate, standby host-bus adaptors (HBAs) for alternate nodes with respect to a node with the duplicate, standby HBAs using duplicate credentials of active HBAs of the node for shutting down the node, taking an active HBA of the node offline, and/or activating one of the alternate nodes.

Efficient high availability for a scsi target over a fibre channel

Method and system is provided for managing metadata for a plurality of data containers that are stored at one or more storage volumes in a clustered storage system The metadata is collected from one or more storage volumes and then provided to a catalog module The catalog module pre-processes the metadata and then generates a searchable data structure The searchable data structure may then be used to respond to a user request for information regarding the storage system

Method and system for managing metadata in a cluster based storage environment

Method and system is provided for managing metadata for a plurality of data containers that are stored at one or more storage volumes in a storage system. The metadata is collected from one or more storage volumes and then provided to a catalog module. The catalog module pre-processes the metadata and then generates a searchable data structure. The searchable data structure may then be used to respond to a user request for information regarding the storage system.

Method and system for managing metadata in a storage environment

A data security appliance intercepts out-of-band control traffic directed to a data storage device, wherein the out-of-band control traffic includes a command to change a configuration of the data storage device. The data security appliance is reconfigured in accordance with the command in order to conform with a new configuration of the data storage device.

Storage security appliance with out-of-band management capabilities

A security appliance that encrypts and decrypts information is installed in each of redundant multi-paths between a host system and a back up tape storage system. The host system is arranged to detect failures in a primary path to the tape system being used. When the failure is detected, the host system enables transfers to the same tape system through an alternative path. Encryption keys and host/tape designators (identifiers) are broadcast among the security appliances in the alternative data paths. When the host system switches from the primary path to the secondary path, even though the secondary security appliance did not generate the encryption keys, the secondary path security appliance will have such keys and will properly encrypt and transfer data from the host to the tape system. The secondary will also properly retrieve encrypted data from the tape system, decrypt it and deliver it to the host. All of these operations will be transparent (invisible) to a running application in the host.
