摘要： Systems and methods for managing a virtual tape library (VTL) domain capable of being coupled to a host are provided. One system includes a plurality of VTL nodes configured to store multiple scratch erased volumes. Each VTL node comprises a processor configured to perform at least a portion of the below method. One method includes receiving a request from the host to de-mount a volume in one of the plurality of VTL nodes, transferring the volume to a scratch category in response to receiving the request, erasing data in the volume and categorizing the volume as a scratch erased volume, and providing ownership of the scratch erased volume to a VTL node in the plurality of VTL nodes based on pre-determined criteria for the plurality of VTL nodes. Also provided are computer storage mediums including computer code for performing the above method.

摘要： Systems and methods for backing up storage volumes are provided. One system includes a primary side, a secondary side, and a network coupling the primary and secondary sides. The secondary side includes first and second VTS including a cache and storage tape. The first VTS is configured to store a first portion of a group of storage volumes in its cache and migrate the remaining portion to its storage tape. The second VTS is configured to store the remaining portion of the storage volumes in its cache and migrate the first portion to its storage tape. One method includes receiving multiple storage volumes from a primary side, storing the storage volumes in the cache of the first and second VTS, migrating a portion of the storage volumes from the cache to storage tape in the first VTS, and migrating a remaining portion of the storage volumes from the cache to storage tape in the second VTS.

摘要： In a storage system including plural source storage devices, a target storage device selects which source storage device to accept a copy request from the target storage device so as to minimize the load on the entire system. The system calculates first and second load values for job loads being processed. System load values for the system are derived from job load value of a specific data, and respective load values for first and second source storage devices. The system compares the system load values to select a storage device to provide the data copy so as to minimize the load on the entire system.

摘要： Each file is assigned in advance with a WWUID, newly assigned to a file upon the creation or update of the file and inherited from a file to a copied file when it is copied. In a backup apparatus, a file name reception unit receives the file name of a backup target file. A WWUID reception unit receives a WWUID corresponding to the file name. A WWUID search unit searches for the same WWUID in backup management information of a previous day stored in a backup destination. Only if the search is failed, a file operation instruction unit instructs the storing of the backup target file into the backup destination. Then, an Rcnt update instruction unit instructs the updating of the number of references made to the WWUID within the backup destination. A second management information update instruction unit then instructs updating of backup management information of the current day.
摘要翻译：每个文件都预先分配给一个WWUID，在创建或更新文件时新分配给一个文件，并在文件被复制时从文件继承到复制的文件。在备份装置中，文件名接收部接收备份对象文件的文件名。 WWUID接收单元接收与文件名对应的WWUID。 WWUID搜索单元在存储在备份目的地的前一天的备份管理信息中搜索相同的WWUID。只有当搜索失败时，文件操作指令单元指示将备份目标文件存储到备份目的地中。然后，Rcnt更新指示单元指示对备份目的地内的WWUID的引用次数的更新。然后，第二管理信息更新指示单元指示当前日子的备份管理信息的更新。
