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

A device creates a first cloud storage container in a first region of cloud storage, clears a delete flag associated with the first cloud storage container, and stores a first data object in the first cloud storage container in the first region of cloud storage. The device receives a request to delete the first cloud storage container, sets a delete flag associated with the first cloud storage container based on the request to delete the first cloud storage container, and deletes the first cloud storage container if the request to delete has not been rescinded prior to expiration of a time period.

Cloud-based storage deprovisioning

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 storage environment

In one embodiment, a data migration technique enables a source storage system to efficiently and reliably migrate data to a destination storage system. The source storage system includes a copy engine that is configured to migrate or copy a set of data, e.g., one or more files, to the destination storage system using a file-based protocol over a network. The copy engine is also configured to ensure that any locks associated with the migrated data set are reclaimed at the destination storage system using a lock-based protocol. The source storage system further includes a proxy service that is configured to translate client requests to access the migrated data set to access requests executable (i.e., discernable) by the destination storage system. The proxy service then forwards or proxies the translated requests over the network to the destination storage system for processing. In essence, the proxy service interacts with the copy engine to proxy protocol specific requests and replies between a client and the destination storage system after copying of the migrated data set has completed, thus rendering data migration transparent to the client.
