    Abstract: A system and method for migrating data objects based on portions of the data objects is described. The system may transfer portions of files, folders, and other data objects from primary storage to secondary storage based on certain criteria, such as time-based criteria, age-based criteria, and so on. An increment 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 system identifies one or more blocks of a data object that satisfy a certain criteria, and migrates the identified blocks. The system 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.

    Abstract: A system and method for performing an image level restore of data is described. In some examples, the system receives a request to restore a file and transmits the request to an intermediate component. The intermediate component may then retrieve a directory file from an image of a secondary copy of a data set, identify a location of the file from the directory file, and provide the location to the requestor.

    Abstract: 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.

    Abstract translation: 独立的网络可访问数据存储设备（例如文件管理器或NAS设备）能够基于数据对象的部分来传送数据对象。 设备根据某些标准（例如基于时间的标准，基于年龄的标准等）将部分文件，文件夹和其他数据对象从设备内的数据存储区传输到外部辅助存储。 一部分可以是数据对象的一个​​或多个块，或数据对象的一个​​或多个块，或组合形成或存储数据对象的其他段。 例如，设备识别满足特定标准的数据对象的一个​​或多个块，并将所识别的块迁移到外部存储器，从而释放设备内的存储空间。 该设备可以确定文件系统的特定数量的块在某个时间段内未被修改或调用，并将这些块迁移到辅助存储器。
