Data center virtual tape off-site disaster recovery planning and implementation system
View Patent ↗A system for planning and verifying off-site disaster recovery plans as well as implementing alternate fall back operations in the event of a disaster. The system includes at least one primary mainframe computer having an inboard catalog component, a primary emulated device controller connected to the primary computer, and a primary virtual tape system connected to the primary computer. A primary virtual tape system catalog is connected to the primary virtual tape system. A disaster recovery administrator using remote management tools maintains user and resource profiles and controls configuration of the primary emulated device controller and the primary virtual tape system. A disaster recovery facility includes at least one customer virtual tape system including a virtual tape system catalog component, a terminal emulator in communication with a disaster recovery mainframe computer and a disaster recovery virtual tape system having a virtual tape system catalog in communication with the disaster recovery mainframe wherein customer virtual tape system images are mirrored on the disaster recovery virtual tape system and catalog information from the customer virtual tape catalog is mirrored on the disaster recovery tape system of the disaster recovery facility.
1. A process for planning, verifying and implementing a virtual tape off-site disaster recovery system, which process comprises: storing tape images from a primary mainframe computer on a primary virtual tape system: storing tape catalog information from said primary mainframe computer on a primary VTS catalog; duplicating or mirroring catalog information from said primary VTS catalog on a customer VTS catalog at a disaster recovery facility; periodically transferring or copying tape images from said primary virtual tape system to a disaster recovery facility remote data storage client device; storing tape images from said remote data storage client device on a large disk array at said disaster recovery facility; and remotely verifying and testing various disaster recovery plans via remote management tools, comprising the steps of: accessing information and data stored on an arbitrary data repository at said disaster recovery facility by a remote security administrator; associating said disaster recovery facility remote data storage client device to said customer VTS catalog at said disaster recovery facility by said remote security administrator; severing any existing connection between said primary virtual tape system and said disaster recovery facility; accessing a disaster recovery mainframe at said disaster recovery facility by said remote security administrator; wherein said step of remotely verifying and testing various disaster recovery plans further comprises the steps of: restoring said disaster recovery mainframe using said tape images from said remote data storage client device stored on said disk array at said disaster recovery facility to form a restored instance of said primary mainframe computer on said disaster recovery mainframe at said disaster recovery facility; accessing a hardware management console at said disaster recovery facility by said remote security administrator in order to initiate an initial program load of said disaster recovery mainframe; and activating and operating said restored instance of said primary mainframe computer on said disaster recovery mainframe at said disaster recovery facility.
