Abstract: Multiple data paths may be available to a data management system for transferring data between a primary storage device and a secondary storage device. The data management system may be able to gain operational advantages by performing load balancing across the multiple data paths. The system may use application layer characteristics of the data for transferring from a primary storage to a backup storage during data backup operation, and correspondingly from a secondary or backup storage system to a primary storage system during restoration.

Abstract: According to certain aspects, an information management system may be configured to: receive system information relating to one or more data storage requirements associated with a first user; access an electronic database containing deployment configuration rules usable in determining information management cell configurations; generate a recommended deployment configuration for an information management cell associated with the first user based at least in part on the system information and the deployment configuration rules; receive computing infrastructure information relating to computer hardware components within the information management cell that are available for use in implementing the recommended deployment configuration; and generate an installation script for the information management cell based at least in part on the recommended deployment configuration and the computing infrastructure information.

Abstract: Certain embodiments described herein relate to an improved selective data backup system. In some embodiments, one or more components in an information management system can determine that a portion of the primary data scheduled for backup was previously backed up or is scheduled to be backed up as part of another backup operation. For example, a data agent performing a cluster-level backup operation for an entire cluster of storage servers may check whether any part of the primary data was previously backed up by a prior server-level backup operation for one of the storage servers in the cluster. If so, the data agent may skip, in the cluster-level backup operation, any portion of the primary data stored in the storage server previously backed up as part of the prior server-level backup operation.

Abstract: Techniques for providing data preview before recalling large data files are disclosed. In one aspect, a data file is made accessible while being offline by converting the data file from a native format to a preview format, storing the data file in the preview format in a primary storage that is locally available and moving, after the conversion to the preview format, the data file in the native format to a secondary storage. When a viewing request is received for the data file, the data file in the preview format is displayed to fulfill the viewing request.

Abstract: Described in detail herein are systems and methods for single instancing blocks of data in a data storage system. For example, the data storage system may include multiple computing devices (e.g., client computing devices) that store primary data. The data storage system may also include a secondary storage computing device, a single instance database, and one or more storage devices that store copies of the primary data (e.g., secondary copies, tertiary copies, etc.). The secondary storage computing device receives blocks of data from the computing devices and accesses the single instance database to determine whether the blocks of data are unique (meaning that no instances of the blocks of data are stored on the storage devices). If a block of data is unique, the single instance database stores it on a storage device. If not, the secondary storage computing device can avoid storing the block of data on the storage devices.

Abstract: A data storage system can scan one or more information stores of primary storage and analyze the metadata of files stored in the one or more information stores of primary storage to identify multiple, possibly relevant, secondary copy operations that can be performed on the files. The storage system can also identify primary storage usage information of each file during the scan and use that information to generate reports regarding the usage of the primary storage.

Abstract: A system and method to perform data management operations in a data management system assigns the data management request to one or more available data management resources. If the data management request fails, at least one data management resource at least partially responsible for the failure is determined, as is a category associated with the one data management resource at least partially responsible for the failure. Other data management requests are identified in a list of data management requests that request data management resources having the same category and the list of data management requests is updated to indicate that the data management system should not perform the other identified data management requests.

Abstract: Expandable cache management dynamically manages cache storage for multiple network shares configured in a file server. Once a file is written to a directory or folder on a specially designated network share, such as one that is configured for “infinite backup,” an intermediary pre-backup copy of the file is created in an expandable cache in the file server that hosts the network share. On write operations, cache storage space can be dynamically expanded or freed up by pruning previously backed up data. This advantageously creates flexible storage caches in the file server for each network share, each cache managed independently of other like caches for other network shares on the same file server. On read operations, intermediary file storage in the expandable cache gives client computing devices speedy access to data targeted for backup, which is generally quicker than restoring files from backed up secondary copies.

Abstract: Systems and methods for providing automated problem reporting in elements used in conjunction with computer networks are disclosed. The system comprises a plurality of elements that perform data migration operations and a reporting manager or monitor agent which monitors the elements and data migration operations. Upon detection of hardware or software problems, the reporting manager or monitor agent automatically communicates with elements affected by the problem to gather selected hardware, software, and configuration information, analyzes the information to determine causes of the problem, and issues a problem report containing at least a portion of the selected information. The problem report is communicated to a remote monitor that does not possess access privileges to the elements, allowing automated, remote monitoring of the elements without compromising security of the computer network or elements.
