    • With respect to an administrator in a data management system, although an authority to see contents of data is not granted depending on a job of the administrator, it is necessary to acquire information of a volume in order to replicate the data on a computer in a job such as a replication of the data at the time of managing a storage system, and since the data can also be operated by the administrator who replicates the data, there is a problem from the view point of security. A volume to encrypt and decrypt is determined by a user management program 112 of a management computer 100 according to a user's job. Further, as to whether to encrypt or whether to decrypt, a command of yes/no of the encryption and decryption is given to an encryption apparatus in accordance with the authority in an application of the user so as to perform the job such as performing the data replication by the encrypted data. Moreover, when it seems not possible to judge the encryption and decryption by the encryption apparatus, a path is set up without passing through the encryption apparatus so as to have a host recognize the data as is encrypted.
    • 对于数据管理系统中的管理员来说,尽管取决于管理员的工作而不授予查看数据内容的权限,但是需要获取卷的信息以便在计算机上复制数据 诸如在管理存储系统时复制数据的作业,并且由于数据也可以由复制数据的管理员操作,所以从安全性的角度来看存在问题。 加密和解密的卷由管理计算机100的用户管理程序112根据用户的工作来确定。 此外,关于是否进行加密还是解密,根据用户的应用程序的权限向加密装置提供加密和解密的是/否的命令,以便执行诸如执行 数据复制由加密数据。 此外,当看起来不可能判断加密装置的加密和解密时,建立路径而不通过加密装置,以使主机识别出加密的数据。

    • The invention provides a method for computing the appropriate capacity of a journal volume based on the operating patterns of backup and recovery performed by the user, and composing a recovery system that enables recovery to be performed in a short time using journals. The invention provides a computer system comprising a storage system 120 having a volume 124, a managing computer 100 and a host computer 110, wherein the storage system 120 retains a journal of data stored in the volume and a volume replicating the data stored in the volume, and restoring a volume data at any update time point based on the journal and the replicated volume, and upon receiving operation from a user regarding the volume retaining the journal, the managing computer 100 acquires a registration creation demand including a recovery time objective which is the time to be restored and/or a recovery point objective which is the recovery time point and a journal retention period which is the period for retaining the journal, monitors the journal of data stored in the volume, computes the quantity of the journal, and determines the capacity of the volume for retaining the journal.
    • 本发明提供了一种用于基于用户执行的备份和恢复的操作模式来计算日志卷的适当容量的方法,以及组合恢复系统,其使得能够在短时间内使用期刊来执行恢复。 本发明提供了一种包括具有卷124的存储系统120,管理计算机100和主计算机110的计算机系统,其中存储系统120保存存储在卷中的数据期刊,以及复制存储在卷中的数据的卷 ,以及基于日志和复制卷在任何更新时间点恢复卷数据,并且在从用户接收到关于保留日志的卷的操作时,管理计算机100获取包括恢复时间目标的注册创建需求,该恢复时间目标是 要恢复的时间和/或作为恢复时间点的恢复点目标和作为保留期刊的期间的期刊保留期间,监视存储在卷中的数据的期刊,计算期刊的数量,以及 确定保留期刊的卷的容量。
