| 20120079326 | System Health Monitor - Backup set metadata is received, wherein the backup set metadata comprises information about backup data sets that are received by a backup storage system that stores the backup data sets. The manner in which the backup data sets flow through a processing flow path of the backup storage system is emulated. One or more processes that process the backup set metadata through an emulated processing flow path are executed, wherein the emulated processing flow path is indicative of the manner in which the backup data sets flow through the processing flow path of the backup storage system when the backup storage system stores the backup data sets. One or more timing statistics are calculated based on the flow of the backup set metadata through the emulated processing flow path. | 03-29-2012 |
| 20120079325 | System Health Monitor - Described are computer-based methods and apparatuses, including computer program products, for system health monitoring. Backup set metadata is received, wherein the backup set metadata comprises information about backup data sets that are received by a backup storage system. One or more processes that process the backup set metadata through an emulated processing flow path are executed, wherein the one or more processes are also implemented in the backup storage system. Two or more potential processing states are determined within the emulated processing flow path. A reason code is determined for each backup set metadata entry of the backup set metadata indicative of a reason that the backup set metadata entry is in a processing state of the two or more potential processing states. A problem with the manner in which the backup set metadata is flowing through the emulated processing flow path is identified based on the reason codes. | 03-29-2012 |
| 20120066193 | Distributed Garbage Collection - Described are computer-based methods and apparatuses, including computer program products, for garbage collection. A garbage collection data structure is provided for deleting unused data objects. One or more object identifiers are stored in a first data structure in the garbage collection data structure. Each object identifier represents a data object about to be created but not yet assigned any references from other data objects. The first data structure prevents the data object from being deleted during creation of the data object but before one or more references are created to the data object. Data indicative of one or more objects is stored in a second data structure in the garbage collection data structure. The data includes one or more object identifiers, each object identifier representing a created data object. The data also includes one or more references to created data objects. | 03-15-2012 |
| 20110185133 | System and Method for Identifying Locations Within Data - Described are computer-based methods and apparatuses, including computer program products, for removing redundant data from a storage system. In one example, a data delineation process delineates data targeted for de-duplication into regions using a plurality of markers. The de-duplication system determines which of these regions should be subject to further de-duplication processing by comparing metadata representing the regions to metadata representing regions of a reference data set. The de-duplication system identifies an area of data that incorporates the regions that should be subject to further de-duplication processing and de-duplicates this area with reference to a corresponding area within the reference data set. | 07-28-2011 |
| 20110184967 | System and method for navigating data - Described are computer-based methods and apparatuses, including computer program products, for removing redundant data from a storage system. In one example, a data delineation process delineates data targeted for de-duplication into regions using a plurality of markers. The de-duplication system determines which of these regions should be subject to further de-duplication processing by comparing metadata representing the regions to metadata representing regions of a reference data set. The de-duplication system identifies an area of data that incorporates the regions that should be subject to further de-duplication processing and de-duplicates this area with reference to a corresponding area within the reference data set. | 07-28-2011 |
| 20110184966 | System and Method for Summarizing Data - Described are computer-based methods and apparatuses, including computer program products, for removing redundant data from a storage system. In one example, a data delineation process delineates data targeted for de-duplication into regions using a plurality of markers. The de-duplication system determines which of these regions should be subject to further de-duplication processing by comparing metadata representing the regions to metadata representing regions of a reference data set. The de-duplication system identifies an area of data that incorporates the regions that should be subject to further de-duplication processing and de-duplicates this area with reference to a corresponding area within the reference data set. | 07-28-2011 |
| 20110184921 | System and Method for Data Driven De-Duplication - Described are computer-based methods and apparatuses, including computer program products, for removing redundant data from a storage system. In one example, a data delineation process delineates data targeted for de-duplication into regions using a plurality of markers. The de-duplication system determines which of these regions should be subject to further de-duplication processing by comparing metadata representing the regions to metadata representing regions of a reference data set. The de-duplication system identifies an area of data that incorporates the regions that should be subject to further de-duplication processing and de-duplicates this area with reference to a corresponding area within the reference data set. | 07-28-2011 |
| 20090182789 | SCALABLE DE-DUPLICATION MECHANISM - A method for removing redundant data from a backup storage system is presented. In one example, the method may include receiving the application layer data object, selecting a de-duplication domain from a plurality of de-duplication domains based at least in part on a data object characteristic associated with the de-duplication domain, determining that the application layer data object has the characteristic and directing the application layer data object to the de-duplication domain. | 07-16-2009 |
| 20090177661 | EMULATED STORAGE SYSTEM - Systems and methods for efficient storage of data are provided. For instance, a method that includes acts of receiving a data stream to be stored on a first storage system, the data stream comprising a data object and metadata that describes attributes of the data object, extracting the metadata from the data stream, storing the data object on the first storage system and storing the extracted metadata, separately from the data object, on a computer-readable medium is disclosed. Additionally, a storage system is disclosed that includes a first storage medium, an interface configured to receive a data stream including a data object to be stored on the first storage medium and a controller. The controller may be configured to extract metadata from the data stream, the metadata being descriptive of attributes of the data object, and to direct the extracted metadata to be stored on a computer-readable medium. | 07-09-2009 |
| 20090172326 | EMULATED STORAGE SYSTEM SUPPORTING INSTANT VOLUME RESTORE - In a back-up storage system, an apparatus and methods for mounting a data volume corresponding to a back-up data set to a host computer. In one example, a method includes mounting a data volume on a host computer, the data volume comprising at least one data file, the data file corresponding to a most recently backed-up version of the at least one data file stored on a backup storage system, and storing, on the backup storage system, data corresponding to a second version of the at least one data file that is more recent than the most recently backed-up version of the at least one data file stored on the backup storage system while preserving the most recently backed-up version of the at least one data file. | 07-02-2009 |
