| 20100070466 | DATA TRANSFER TECHNIQUES WITHIN DATA STORAGE DEVICES, SUCH AS NETWORK ATTACHED STORAGE PERFORMING DATA MIGRATION - A stand-alone, network accessible data storage device, such as a filer or NAS device, is capable of transferring data objects based on portions of the data objects. The device transfers portions of files, folders, and other data objects from a data store within the device to external secondary storage based on certain criteria, such as time-based criteria, age-based criteria, and so on. A portion may be one or more blocks of a data object, or one or more chunks of a data object, or other segments that combine to form or store a data object. For example, the device identifies one or more blocks of a data object that satisfy a certain criteria, and migrates the identified blocks to external storage, thereby freeing up storage space within the device. The device may determine that a certain number of blocks of a file have not been modified or called by a file system in a certain time period, and migrate these blocks to secondary storage. | 03-18-2010 |
| 20100082672 | SYSTEMS AND METHODS FOR MANAGING SINGLE INSTANCING DATA - Described in detail herein are systems and methods for managing single instancing data. Using a single instance database and other constructs (e.g. sparse files), data density on archival media (e.g. magnetic tape) is improved, and the number of files per storage operation is reduced. According to one aspect of a method for managing single instancing data, for each storage operation, a chunk folder is created on a storage device that stores single instancing data. The chunk folder contains three files: 1) a file that contains data objects that have been single instanced; 2) a file that contains data objects that have not been eligible for single instancing; and 3) a metadata file used to track the location of data objects within the other files. A second storage operation subsequent to a first storage operation contains references to data objects in the chunk folder created by the first storage operation instead of the data objects themselves. | 04-01-2010 |
| 20100299490 | BLOCK-LEVEL SINGLE INSTANCING - 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. | 11-25-2010 |

| 20100250549 | STORING A VARIABLE NUMBER OF INSTANCES OF DATA OBJECTS - Described are systems and methods for storing a variable number of instances of data objects (e.g., 1, 2, 3, or up to N-1 instances, where N is the number of instances of the data object included in primary data) in secondary storage across a data storage network. In some examples, a system for storing a variable number of instances of data objects includes, one or more computing devices storing a set of data objects and multiple storage devices distinct from the one or more computing devices. Each of the multiple storage devices is configured to store at least a single instance of a data object. The system also includes a database configured to store information associated with the data objects. This information includes substantially unique identifiers for the data objects and, for each of the data objects, a number of instances of the data object stored on the multiple storage devices. | 09-30-2010 |
| 20110016091 | DE-DUPLICATION SYSTEMS AND METHODS FOR APPLICATION-SPECIFIC DATA - Content-aware systems and methods for improving de-duplication, or single instancing, in storage operations. In certain examples, backup agents on client devices parse application-specific data to identify data objects that are candidates for de-duplication. The backup agents can then insert markers or other indictors in the data that identify the location(s) of the particular data objects. Such markers can, in turn, assist a de-duplication manager to perform object-based de-duplication and increase the likelihood that like blocks within the data are identified and single instanced. In other examples, the agents can further determine if a data object of one file type can or should be single-instanced with a data object of a different file type. Such processing of data on the client side can provide for more efficient storage and back-end processing. | 01-20-2011 |
