摘要： A technique for eliminating duplicate data is provided. Upon receipt of a new data set, one or more anchor points are identified within the data set. A bit-by-bit data comparison is then performed of the region surrounding the anchor point in the received data set with the region surrounding an anchor point stored within a pattern database to identify forward/backward delta values. The duplicate data identified by the anchor point, forward and backward delta values is then replaced in the received data set with a storage indicator.

摘要： The present invention provides a system and method for estimating duplicate data in a storage system. A duplicate estimation application executes on a client of a storage system selects an element from an intended destination such as, e.g., a data store of the storage system. If the element is a file (or other data container), the application reads data from the file and computes a fingerprint of the read data. The computed fingerprint is then logged in a fingerprint database, which is illustratively stored on a storage device connected to the client executing the application. This process repeats until the entire file (or other data container) has been read and fingerprinted. Once all elements have been scanned, fingerprinted and recorded, the application identifies any unique entries within the fingerprint database. Utilizing this information, the application computes an estimated space savings that may be realized by employing a data de-duplication technique.
摘要翻译：本发明提供一种用于估计存储系统中的重复数据的系统和方法。在存储系统的客户端上执行的重复估计应用从预期目的地（例如，存储系统的数据存储）中选择一个元素。如果元素是文件（或其他数据容器），则应用程序从文件读取数据并计算读取数据的指纹。然后将计算出的指纹记录在指纹数据库中，该指纹数据库被示例性地存储在连接到执行应用程序的客户端的存储设备上。该过程重复，直到整个文件（或其他数据容器）已被读取和指纹。一旦所有元素被扫描，指纹和记录，应用程序将识别指纹数据库中的任何唯一条目。利用该信息，应用程序计算可以通过采用重复数据删除技术来实现的估计空间节省。

摘要： According to one or more embodiments of the present invention, a network cache intercepts data requested by a client from a remote server interconnected with the cache through one or more wide area network (WAN) links (e.g., for Wide Area File Services, or “WAFS”). The network cache stores the data and sends the data to the client. The cache may then intercept a first write request for the data from the client to the remote server, and determine one or more portions of the data in the write request that changed from the data stored at the cache (e.g., according to one or more hashes created based on the data). The network cache then sends a second write request for only the changed portions of the data to the remote server.

摘要： The present invention is a tape library comprising both a small front-end portion and a larger back-end portion. The front-end portion is a visible virtual or physical tape library; and the back-end portion is a large invisible virtual or physical tape vault. The DPA is a typical DPA which only sees the front-end library. If desired, all messages regarding the importing and exporting of tapes are reviewed by an agent. The agent manages the automatic transfer of tapes between the front-end and the back-end, and notifies the user when a manual import or export is needed. This greatly reduces both the amount of hardware required to establish a virtual or physical tape library and also reduces the amount of labor required by a user to physically import and export tapes. If both the front-end library and the back-end vault are virtual and reside on the same virtual tape library appliance, no data movement is necessary and the tapes can be moved merely by performing small software state changes. In this case, manual operation may be acceptable.
