摘要： An algorithm (such as the MD5 hash function) is applied to a file to produce an intrinsic unique identifier (IUI) for the file (or message digest). The file is encrypted using its IUI as the key for the encryption algorithm. An algorithm is then applied to the encrypted file to produce an IUI for the encrypted file. The encrypted file is safely stored or transferred within a network and is uniquely identifiable by its IUI. The encrypted file is decrypted using the IUI of the plaintext file as the key. The IUI serves as both a key to decrypt the file and also as verification that the integrity of the plaintext file has not been compromised. IUIs for any number of such encrypted files may be assembled into a descriptor file that includes meta data for each file, the IUI of the plaintext file and the IUI of the encrypted file. An algorithm is applied to the descriptor file to produce an IUI for the descriptor file. The plaintext descriptor file is then encrypted using the descriptor file IUI as a key for the encryption algorithm. An algorithm is applied to the encrypted descriptor file to produce an IUI for the encrypted descriptor file. The IUI of the encrypted descriptor file is a location-independent identifier to locate the encrypted descriptor file. A flattened descriptor file includes the IUIs of encrypted data files and the IUI of the encrypted descriptor file. An algorithm is applied to the flattened descriptor file to produce its own IUI.
摘要翻译：一个算法（如MD5哈希函数）被应用于文件以产生文件（或消息摘要）的固有唯一标识符（IUI）。该文件使用其IUI作为加密算法的密钥进行加密。然后将一个算法应用于加密文件，以生成加密文件的IUI。加密的文件在网络中安全地存储或传输，并由其IUI唯一标识。使用明文文件的IUI作为密钥解密加密文件。 IUI既可用于解密文件，也可用作验证明文文件的完整性尚未被泄露。可以将任何数量的这种加密文件的IUI组装成包括每个文件的元数据，明文文件的IUI和加密文件的IUI的描述符文件。一个算法应用于描述符文件以产生描述符文件的IUI。然后使用描述符文件IUI作为加密算法的密钥来加密明文描述符文件。将一种算法应用于加密的描述符文件，以生成加密描述符文件的IUI。加密描述符文件的IUI是一个位置无关的标识符来定位加密的描述符文件。扁平化描述符文件包括加密数据文件的IUI和加密描述符文件的IUI。一个算法应用于展平描述符文件以产生自己的IUI。

摘要： Some embodiments are directed to a technique for storing and/or locating content units stored on an object addressable storage (OAS) system, wherein each content unit is identified by an object identifier. The OAS system may comprise a plurality of zones, each of which stores content units. A mapping process may be defined that maps object identifiers for content units to zones on the OAS system. Thus, the storage location for a content unit on the OAS system may be the zone on the OAS system to which the object identifier for the content unit maps.

摘要： One aspect involves mounting a file system stored on a CAS system. The file system has a directory structure that includes a plurality of directories arranged in a hierarchy and including a root directory at the top of the hierarchy. Each of the directories is represented by a content unit stored on the CAS system, the content unit having a content address that is computed based, at least in part, on at least a portion of the content of the content unit. The file system is mounted by specifying the content address of the content unit that represents the root directory and determining the file system to be mounted based on the content address of the content unit that represents the root directory.

摘要： Access to content addressable data on a network is facilitated using digital information storing devices or data repositories (“silos”) that monitor broadcast data requests over the network. A number of silos automatically monitor both data requests and data itself that are broadcast over a network. The silos selectively store data. Each silo responds to data requests broadcast over the network with data the silo has previously intercepted. A content addressable file scheme is used to enable the data repositories to reliably identify data being requested. When a data request is received, each silo evaluates whether it has all or a portion of the data being requested and responds to requests when it has the data. Requests for data are implemented by broadcasting a cryptographic hash data identifier of the data file needed. The data identifier is used by a silo to determine which data to receive and store.

摘要： One embodiment is a system for locating content on a storage system, in which the storage system provides a location hint to the host of where the data is physically stored, which the host can resubmit with future access requests. In another embodiment, an index that maps content addresses to physical storage locations is cached on the storage system. In yet another embodiment, intrinsic locations are used to select a storage location for newly written data based on an address of the data. In a further embodiment, units of data that are stored at approximately the same time having location index entries that are proximate in the index.

摘要： Representing a number of assets on an originating computer begins with selecting the assets to be represented. Cryptographic hash asset identifiers are generated; each of the asset identifiers is computed using the contents of a particular asset. The asset identifier is a content-based or content-addressable asset name for the asset and is location independent. An asset list is generated that includes the asset identifiers computed from the assets. A cryptographic hash asset list identifier is generated that is computed from the asset list. The asset list identifier is stored for later retrieval. The assets selected are also stored for safekeeping either locally or on a computer network. In the event of loss of the files from the originating computer, the asset list identifier is retrieved. Using the asset list identifier, the original asset list is found and retrieved from its safe location. The asset identifiers from the retrieved asset list are used to find and retrieve the individual assets from their backup locations. The assets are verified by recomputing the cryptographic hash asset identifier for each asset retrieved and comparing it to the asset identifier from the asset list. The MD5 algorithm is used for the cryptographic hash function. Assets are retrieved using a multicast protocol. A series of importer programs searches for assets to retrieve in progressively more remote locations. Assets are retrieved whole or in segments.

摘要： A system and method are provided for retention of data on a storage system. An application program provides the storage system with data to be stored on the storage system. The application program also provides the storage system with a retention period that indicates a period of time for which the data may not be deleted. When the storage system receives a request to delete the data, it first evaluates the retention period associated with that data to determine if the retention period has expired. If the retention period has not expired, the storage system denies the request to delete the data.
