  • Patent number: 10089148
    Abstract: 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.

  • Patent number: 8949560
    Abstract: In one aspect, a method includes obtaining data on components of a virtualization server comprising acquiring a mapping of virtual disks in a virtual store to storage disks, obtaining data on components of a storage array comprising acquiring a mapping of logical units in the storage array to the storage disks, the logical units replicating data from a corresponding storage disk, correlating each virtual disk to a logical unit based on the mapping of the virtual disks to the storage disks and the mapping of the logical units to the storage disks, retrieving replication data of the logical units from the storage arrays and, for a selected virtual store, checking that the selected virtual store has a replica for all the required storage disks mapped to the virtual disks of the selected virtual store.

  • Patent number: 8151069
    Abstract: Providing a multiple protection snapshot copy of a logical device includes creating the snapshot copy of the logical device, where, in response to a write to a section of the logical device, data is copied to a first alternative storage area prior to the write and, following creating the snapshot copy, pointing portions of the snapshot copy to a second alternative storage area having data that is a copy of the logical device, where data corresponding to the snapshot copy is stored in one of: the first alternative storage area and the second alternative storage area. Providing a multiple protection snapshot copy of a logical device may also include, prior to pointing portions of the snapshot copy to the second alternative storage area and after creating the snapshot copy, copying data from the logical device to the second alternative storage area.

  • Patent number: 8140484
    Abstract: Described are techniques for determining an implemented data protection policy. One or more recovery points corresponding to each of one or more storage objects are determined. A data protection method determined in accordance with a facility and replication type associated with each recovery point is selected for each of the one or more recovery points. A data protection category for each of the one or more recovery points is determined in accordance with the data protection method, a recovery point type, and a recovery point location associated with each recovery point. A data protection policy indicating an implemented data protection policy for each of the one or more storage objects for at least one data protection category is stored.
