Abstract

A method and system is disclosed for identifying and applying service recovery units to recover Information Technology (IT) services and IT enabled business services. The service recovery units aid in cost estimation, labor estimation as well as recovery time estimation of the IT services and IT enabled business services.

Method and System for Identifying and Applying Service Recovery Units to Recover Information Technology (IT) Services and IT Enabled Business Services

Disclosed is a method and system for identifying and applying Service Recovery Units (SRUs) to recover Information Technology (IT) services and IT enabled business services. The recovery of IT services and IT enabled business services may be decomposed into several SRUs. Each SRU of the several SRUs may have specific technologies, tools, skills, procedures and inputs, such as external dependencies or conditions, required to recover specific recovery unit. In addition, each SRU may have an expected average time to recover, provided certain preconditions are satisfied in advance.

For example, consider an Operating System (OS) Image as a SRU wherein an OS tool is used for image-based recovery. This SRU requires system administration skills and availability of appropriately configured and compatible server hardware network for image based recovery. The average time required for recovery associated with this SRU is 30 minutes. In another example, consider a file system backup as another SRU. In addition to backup and recovery administrator skills, this SRU requires a backup and restore tool that may backup and restore a given file system. Moreover, this SRU requires sufficient disk space to mount the given file system and catalog data about the media that contains the data.

The proposed method and system disclosed herein is based on a data model that defines different classes of SRU with a set of attributes associated with each class. Certain attributes may be associated with multiple classes of SRUs. Examples of classes include, a Commercial Off-The-Shelf (COTS) application, an application custom, a database, a COTS middleware, a middleware custom, a server OS including Virtual Servers, a server hardware, a network OS, a network hardware, a storage OS, a storage hardware, an appliance OS and an appliance hardware. An example of an attribute that may be associated with each class includes image management system and install/recovery script for technologies and tools needed to recover a specific recovery unit. Similarly, skills and procedures needed to recover the specific recovery unit include system administration and application administration skills. Likewise, for external dependencies or conditions, the required inputs include a server hardware for OS recovery from the OS image, a data center floor space for the server hardware and a physical connectivity to power network and storage systems. As such, the expected average time for recovery is 10 minutes for 5 to 10 GB OS Image via a 1 GB recovery network, provided certain preconditions are satisfied.

Hence, once a comprehensive class of recovery units are identified and defined with a set of attributes, the classes are used as inputs...
