    摘要： A system and method described herein allows a virtual tape library (VTL) to perform multiple simultaneous or parallel read/write or access sessions with disk drives or other storage media, particularly when subject to a sequential SCSI-compliant layer or traditional limitations of VTLs. In one embodiment, a virtualizing or transaction layer can establish multiple sessions with one or more clients to concurrently satisfy the read/write requests of those clients for physical storage resources. A table or other data structure tracks or maps the sessions associated with each client and the location of data on the physical storage devices.

    摘要： A method and system for reducing storage requirements and speeding up storage operations by reducing the storage of redundant data includes receiving a request that identifies one or more data objects to which to apply a storage operation. For each data object, the storage system determines if the data object contains data that matches another data object to which the storage operation was previously applied. If the data objects do not match, then the storage system performs the storage operation in a usual manner. However, if the data objects do match, then the storage system may avoid performing the storage operation.

    摘要翻译： 通过减少冗余数据的存储来减少存储要求和加速存储操作的方法和系统包括接收标识用于应用存储操作的一个或多个数据对象的请求。 对于每个数据对象，存储系统确定数据对象是否包含与之前应用存储操作的另一个数据对象相匹配的数据。 如果数据对象不匹配，则存储系统以通常的方式执行存储操作。 但是，如果数据对象匹配，则存储系统可能会避免执行存储操作。

    摘要： A system and method for setting global actions in a data storage system is described. In some examples, the system determines a policy based on information from the system, and implements that policy to the system. In some examples, the system adds or modifies global filters based on information from the system.

    摘要： A method in a computer system for retrieving data from one of multiple copies of the data is provided, referred to as the data management system. The data management system receives a request identifying at least one data object to be accessed. Then, the data management system queries a metabase to locate data copies that contain the identified at least one data object, wherein the data copies are created from similar source data, and wherein for each data copy the metabase contains an indication of the availability of the copy relative to other copies. Next, the data management system determines one of the located data copies to use to access the identified at least one data object, wherein the determination is made based on the indicated availability contained in the metabase for each of the located data copies. Then, the data management system accesses the identified at least one data object using the determined one of the located data copies.
