Currently, administrators configure replication manually according to a data protection policy. Typically, such data protection policies are provided via a script or a similar input to provision storage devices. However, such manual configuration is subject to administrator error. For example, an administrator may not provision storage devices accurately according to a desired data protection policy. Further, this process is subject not only to human mistake, but also the administrative overhead required to manually provision the storage devices. Example embodiments of the present invention eliminate administration and reliability issues arising out of manual replication service configuration, thereby minimizing administrative costs and improving the user experience of handling data protection. Example embodiments of the present invention provide a method, an apparatus and a computer-program product for creating a policy-based replication service. The method includes receiving a policy and creating a replication service according to the policy.

IT organizations are challenged with maintaining data application and availability while satisfying service level agreements and compliance requirements. Unprecedented data growth is straining IT resources requiring greater investments, while capital and operational expenses are under scrutiny. Given this tension, IT organizations are seeking efficiency and optimization to regain control and meet business SLAs. Example embodiments of the present invention provide a method, an apparatus, and a computer program product for performing automated data protection with information technology (IT) infrastructure visibility. The method comprises receiving input regarding a desired state of a data protection environment for an IT infrastructure and creating a data protection environment according to the desired state of the data protection environment.

A method of attribute based resource allocation is presented. A resource such as a pool of storage has certain properties or attributes associated with portions of the pool. When a request for storage is needed, the requester provides a selection expression which comprises properties and logical operators. From the selection expression a determination is made to allocate portions of the storage pool which meet the requirements of the selection expression.

Method and system for allocating multiple attribute storage properties to selected data storage resources

A method and apparatus for method for transferring files between a primary storage system and a backup and restore system is described. The system generates collapsed extents which are used to specify data to be backed up to a backup and restore system. The backup and restore system backs up data based on the collapsed extents but records all extents included in the collapsed extents to enable the system to facilitate restoration of the data at a later point in time.

A backup server controls the backing up of data stored on a mass storage subsystem in response to a backup request from a host identifying data to be backed up during a backup operation, the mass storage subsystem storing data in a plurality of mirrored copies. The backup server comprises a discovery module, a preparation module, an execution module and a clean-up module. The discovery module receives the backup request and identifies, during a discovery phase, at least one storage location on the mass storage subsystem on which data to be backed up during the backup operation is stored. The preparation module, during a preparation phase following the discovery phase, enables the mass storage subsystem to sever one of said mirrored copies and make it available to backup server for the backup operation. In addition, prior to enabling the mass storage subsystem to sever one of the mirrored copies, the preparation module will notify the host, which will stop operating in connection with the data from the mass storage subsystem, and after the mirrored copy has been severed, the preparation module will so notify the host so that it can resume operating in connection with data from at least one of the other copies. The execution module, during the execution phase, enables the mass storage subsystem to retrieve data from the at least one storage location and transfer the retrieved data to the backup server to facilitate backup storage. The clean-up up module, during a clean-up phase following the execution phase, verifies that the data to be backed up has been stored in backup storage and enable the mass storage subsystem to re-synchronize the mirrored copies. The backup server also performs a restore operation in response to a restore request from the host.
