摘要： In an asynchronous remote copy system, a primary site keeps a list of data blocks for which changes have been made to a primary file system and transmitted to a secondary file system at a secondary site. When the primary site becomes inoperative, the secondary site begins read/write access to the secondary file system and keeps a snapshot copy of the restart point. Once the primary site becomes operative, the primary file system is restored to the state of the secondary file system at the restart point by using the list of data blocks for obtaining from the snapshot copy the data of the blocks for which changes had been made to the primary file system after the restart point. Then the primary file system is synchronized to the secondary file system, and read/write access is switched back from the secondary file system to the primary file system.

摘要： A snapshot copy facility stores snapshot copies of a production, file system. The snapshot copy facility receives a request for the difference between a specified older snapshot,copy and a specified younger snapshot copy, and responds by returning the difference between the older snapshot copy and the younger snapshot copy. In a preferred implementation, the snapshot copy facility has an index for each snapshot copy for indicating blocks of data in the production file system that have changed between the snapshot copy and a next snapshot copy of the production file system. The indices are scanned for a sequence of the snapshot copies to determine the blocks that have changed, and the snapshot copy facility returns the block numbers and data in the younger snapshot copy for the blocks that have changed.

摘要： A file server maintains a production file system supported by a clone volume, and multiple snapshot file systems supported by respective save volumes in a snapshot queue. Before a data block is modified for the first time after creation of the youngest snapshot, the data block is copied from the clone volume to the save volume of the youngest snapshot. A bit map indicates the blocks that have already been copied, and a block map shows the save block address for each corresponding clone block address. When a new snapshot is created, the bit and block maps are converted to a hash index that is kept linked to the save volume of what had been the youngest snapshot. When other than the oldest snapshot file system is deleted, the respective save volume is retained as a hidden object until it becomes the oldest save volume.

摘要： Consistent updates are made automatically over a wide-area IP network, concurrently with read-only access to the remote copies. A replication control protocol (RCP) is layered over TCP/IP providing the capability for a remote site to replicate and rebroadcast blocks of the remote copy data to specified groups of destinations, as configured in a routing table. A volume multicast layer over RCP provides for multicasting to specified volume extents of the blocks. The blocks are copied at the logical level, so that it does not matter what physical structure is used for storing the remote copies. Save volumes buffer the remote copy data transmitted between the primary or secondary file system volume and the IP network, in order to ensure independence between the replication process, the IP transport method, and the primary file system being replicated.

摘要： A method is used in managing global metadata caches in data storage systems. Space is allocated in a memory of a data storage system to a global metadata cache which is configured to store metadata objects for a plurality of different file systems responsive to file system access requests from the plurality of different file systems. A metadata object associated with a file of a file system of the plurality of different file systems is stored in the global metadata cache. The metadata object is accessed by a plurality of different versions of the file.

摘要： One embodiment is directed to a computer system that includes primary and secondary storage systems. When a request to store a content unit is received, it may be determined whether to store the content unit on the primary storage system or the secondary storage system. In another embodiment, a computer may store information relating to an action to be performed in one of the directories of a file system that corresponds to a period of time. When the period of time to which the directory corresponds arrives, the action may be performed. In another embodiment, a content unit stored on a primary storage system may be copied to a secondary storage system in a computer system. After the content unit has been copied, the secondary storage system may send a delete request to the primary storage system to delete the content unit from the primary storage system.

摘要： One embodiment of the invention is directed to the containerization of content units that are accessed using an identifier. Applicants have appreciated that file systems sometimes impose limits on the number of files that may be stored therein that are too restrictive. Thus, in one embodiment, multiple content units may be stored in a single file, called a container file, in a file system. Each content unit may have an identifier associated with it. When an accessing entity requests access to a previously-stored content unit and provides the identifier for the content unit, the identifier may be used to locate the container file in which the content unit is stored.
摘要翻译：本发明的一个实施例涉及使用标识符访问的内容单元的容器化。申请人已经意识到，文件系统有时限制可能存储在其中的太多限制的文件数量。因此，在一个实施例中，多个内容单元可以被存储在文件系统中的被称为容器文件的单个文件中。每个内容单元可以具有与其相关联的标识符。当访问实体请求访问先前存储的内容单元并提供内容单元的标识符时，可以使用该标识符来定位其中存储内容单元的容器文件。
