    Abstract: Container images may be generated from a backup system that includes a backup of one or more applications from a computing system of an entity. During a backup process, an application can be identified and its storage location in a secondary storage can be tracked or saved in a backup index. Configuration information and data or files created by user interaction with the application can be backed up and the location of the backed up data or files may be stored in the backup index along with the location of the configuration information. Using the backup index, a container image can be created that includes a selected application, its configuration information, and data, if any, created by the application. The container image can be generated from the backup stored in the secondary storage.

    Abstract: The disclosed systems and methods enable an application to start operating and servicing users soon after and during the course of its backup data being restored, no matter how long the restore may take. This is referred to as “instant application recovery” in view of the fact that the application may be put back in service soon after the restore operation begins. Any primary data generated by the application during “instant application recovery” is not only retained, but is efficiently updated into restored data. An enhanced data agent and an associated pseudo-storage-device driver, which execute on the same client computing device as the application, enable the application to operate substantially concurrently with a full restore of backed up data. According to the illustrative embodiment, the pseudo-storage-device driver presents a pseudo-volume to the file system associated with the application, such that the pseudo-volume may be used as a store for primary data during the period of “instant application recovery.”

    Abstract: A data storage system includes a generic snapshot interface, allowing for integration with a wide variety of snapshot-capable storage devices. The generic interface can be a programming interface (e.g., an application programming interface [API]). Using the snapshot interface, storage device vendors can integrate their particular snapshot technology with the data storage system. For instance, the data storage system can access a shared library of functions (e.g., a dynamically linked library [DLL]) provided by the vendor (or another by appropriate entity) and that complies with the specifications of the common programming interface. And by invoking the appropriate functions in the library, the data storage system implements the snapshot operation on the storage device.

    Abstract: The illustrative storage management system uses snapshot technologies and performs block-level analysis thereof and to synthesize full backups of a database, regardless of the database management system (DBMS) and content of the database and without involving native DBMS utilities. Synthetic full copies are created efficiently and use network transport resources sparingly. Successive snapshots of the database may be hardware snapshots and/or software snapshots. The illustrative storage management system tracks which data blocks in the database change over time after a baseline full copy is saved to secondary storage. Only the changed blocks are subsequently moved to secondary storage as incremental backups and are indexed for future reference. A synthetic full backup of the database, at a given point in time, may be created by synthesizing the original full backup with changed blocks from any number of later incremental backups. The synthetic full backup comprises pointers to appropriate data blocks, ignoring intermediate changes, and pointing to the most current data block in secondary storage relative to the given point in time chosen for the synthetic full backup. The illustrative storage management system may restore the synthetic full backup without native DBMS utilities.

    Abstract: Software, firmware, and systems are described herein that migrate functionality of a source physical computing device to a destination physical computing device. A non-production copy of data associated with a source physical computing device is created. A configuration of the source physical computing device is determined. A configuration for a destination physical computing device is determined based at least in part on the configuration of the source physical computing device. The destination physical computing device is provided access to data and metadata associated with the source physical computing device using the non-production copy of data associated with the source physical computing device.

    Abstract: An illustrative “open archive” architecture relieves the immediate need to add network-attached storage (NAS) devices to a storage management system. The open archive architecture provides streamlined access to live production data, which originally was stored on a NAS device but which is archived to secondary storage to free up NAS space. An open-archive server coordinates with an open-archive layer that operates on the NAS device. The open-archive server identifies data sets on the NAS that meet archiving criteria, which are then automatically moved to an open archive in secondary storage. The open archive layer intercepts data-access calls coming into the NAS device, e.g., open calls, read calls, write calls. The intercepted calls are reported to the open-archive server for analysis. If the open-archive server determines that the data referenced in an intercepted call is stored in the open archive, the open-archive server initiates a restore job that recovers the data from secondary storage and stores it back on the NAS device. The intercepted call may now be served from the NAS. These operations occur automatically and do not involve users or their computing devices, and the computing devices operate without data agents for the NAS-based data.

    Abstract: A data storage system allows a user to search a secondary copy such as a back up, archive, or snapshot and receive an abbreviated version of the secondary copy of the file system as a result of the search. The abbreviated version of the secondary copy of the file system may include metadata such as a listing of secondary copy data that correspond with a search term or other filtering criteria provided by the user. An operating system of the user's computing device may mount the abbreviated version so that it can be displayed within a view of the file system of the computing device. Once a user selects one or more desired data objects listed in the abbreviated version, the selected actual one or more data objects are retrieved from secondary storage.
