    摘要: A priority restore agent in a data storage system generates a priority restore data set for a client computer system or device by identifying a set of active data sets and/or a set of key data sets within client system data generated by the client computer system. The priority restore agent looks at or processes file system attributes for the client system data and compares these attributes with predefined restore parameters. The restore parameters may indicate that any file that has been accessed, modified, or created within a particular period of time be included in the priority restore data set. The key data sets may be identified in a set of automated restore rules. A data protection application within the data storage system can restore data in the priority restore data set onto the client computer system after a disaster or system crash.

    摘要: A data storage and protection system includes secondary storage and at least one instance of a high efficiency storage application (“HESA”). The HESA backs up and archives client data stored in primary storage of a client computer system or client node to secondary storage. Archive files generated by the HESA re-use previously backed up client data stored in the secondary storage. In one embodiment, previously backed up client data is re-used for an archive file by organizing the archive file as a hash tree having hash values pointing to the previously backed up client data. In addition, the HESA can maximize available space in the primary storage by replacing previously backed up and/or archived client data in the primary storage with pointers that point to the previously backed up and/or archived client data in secondary storage.

    摘要: A data de-duplication application de-duplicates redundant data on the primary storage read/write pathway of a virtualized server environment. The virtualized server environment comprises one or more server applications operating on a virtualization layer provided on a computer architecture that includes memory (e.g., RAM, cache memory) for temporarily storing data and storage (e.g., disk storage) for persistently storing data. The one or more server applications use the read-write pathway to read data into memory from storage and to write data to storage from memory. The de-duplication application identifies redundant data in memory, storage, or both, and replaces the redundant data with one or more pointers pointing to a single copy of the data. The de-duplication application can operate on fixed or variable size blocks of data and can de-duplicate data either post-process or in-line.

    摘要: Redundant data is identified and eliminated in a network that implements the iSCSI protocol either in-band at the source, in-band at the target, or out-of-band at the target. For in-band de-duplication, a data block included with a write command is assigned a unique identifier that is compared to a database of unique identifiers corresponding to previously written data. If the unique identifier is identical to an existing unique identifier, this indicates that the data block is redundant and has previously been stored elsewhere, in which case it is not stored again. Instead, the storage address specified in the write command may be added to a routing table showing the equivalence of unique identifiers, actual storage addresses, and duplicate storage addresses. When a read request specifying a duplicate storage address is received, the duplicate storage address can be translated to a corresponding unique identifier which points to the actual storage address.

    摘要: A data protection and management solution includes a storage application operated in a tenant computer system and a data protection application hosted in a host computer system as a SaaS application. The storage application generates storage efficient backups of a raw data set stored on the tenant computer system and replicates the backups to the SaaS application. The SaaS application stores the backups and provides one or more data protection and management services, such as offsite backup, offsite archiving, and information lifecycle management, to the tenant computer system. In the event of loss or corruption of all or a portion of the raw data set on the tenant computer system, a recovery module of the storage application can be used to generate a recovered version on the tenant computer system of the raw data set based on the backups replicated to the SaaS application.

    摘要: A data de-duplication application de-duplicates redundant data in the pooled storage capacity of a virtualized storage environment. The virtualized storage environment includes a plurality of storage devices and a virtualization or abstraction layer that aggregates all or a portion of the storage capacity of each storage device into a single pool of storage capacity, all or portions of which can be allocated to one or more host systems. For each host system, the virtualization layer presents a representation of at least a portion of the pooled storage capacity wherein the corresponding host system can read and write data. The data de-duplication application identifies redundant data in the pooled storage capacity and replaces it with one or more pointers pointing to a single instance of the data. The de-duplication application can operate on fixed or variable size blocks of data and can de-duplicate data either post-process or in-line.

    摘要: A high efficiency portable archive implements a storage system running on a virtualization layer to archive point-in-time versions of a raw data set and the storage system itself as a virtual system on archive media. The high efficiency portable archive can be implemented in a variety of computer architectures. The virtualization layer presents to the storage system a normalized representation of a set of hardware based on components of the computer architecture, shielding the storage system from the actual hardware components of the computer architecture. The storage system and point-in-time versions of the raw data set can be restored to any hardware subsystem that supports the virtual system.

    摘要: Information from multiple databases is retrieved and stored on a database storage system. Multiple point-in-time copies are obtained for each database. A point-in-time copy retrieves data changed in the database since the retrieval of a previous point-in-time copy. A virtual database (VDB) is created by creating a set of files in the data storage system. Each file in the set of files created for a VDB is linked to the database blocks on the database storage system associated with a point-in-time copy of the source database. The set of files associated with the VDB are mounted on a database server allowing the database server to read from and write to the set of files. Workflows based on VDBs allow various usage scenarios based on databases to be implemented efficiently, for example, testing and development, backup and recovery, and data warehouse building.
