Restoration and Recovery Plan - Essay Example In this paper an attempt is made to understand the Restoration and recovery plan employed by an organization in case of any of an attack or failure of its Information System and also to investigate how the organization manages the scenarios that involve alteration, deletion or destruction of data. The organization chosen for the study of the subject is a Ceramic manufacturing company with roughly 1300 employees. Information System: The organization has deployed an in-house web based ERP system that's essentially serves to integrate its Accounts, HR, Payroll, Inventory & Stores, Commercial Department, Sales, and Fixed Asset wings. The ERP application is deployed on Oracle Application Server with Apache web server. The company has twenty nodal offices spread across the city , all nodal offices are connected in a ring topology through fiber as well as through ISDN lines in order to maintain a 24x7 availability . The nature of work is essentially online transactional processing but owing to the integration of Inventory, it also has data warehousing application. All the twenty sites are centrally managed. A centralized Oracle 10g database hosts the data .The database is ported on two IBM p-series 570 H servers . . The operating system is IBM's AIX -5 L versions 5.3. The storage used is IBM's Fast T-700 storage. High Availability Set-up : The two IBM AIX servers are clustered through IBM's High Availability Cluster Multi Processing (HACMP) version 5.3 . The cluster is operating in cascade mode. In case one node fails due to failure or any kind of attack than the other node detects such a collapse and takes over the entire work load and consequently within four minutes, the business operations are restored. HACMP has emerged as one of the most successful high availability software that provides data protection in case of server failover through multi-connects between the servers to a shared storage through clustering software ("The Benefits", n.d.) Data Protection : The data is stored in IBM's Fast T 700 storage . Redundant Array of Independent Disks (RAID) 1+0 is implemented to optimize the storage for fault tolerance. It provides disk mirroring that duplicates the data between the two disks. So that if one disk gets corrupt or develops any fault than the lost data can be retrieved through its mirrored copy. Such a mirrored configuration also optimizes the performance through striping the data across the mirrored disks. ("RAID 10 overview", n.d.). Data Backups : The data backups constitute the most important part of the IT policy of a company. The data-backups ensure recovery of essential data whenever there is any kind of data loss by way of any file corruption, data stealing or manual transactional error. There are many options available to back-up and recover the data .Almost all the companies employ two procedures to backup the data , hot backup and cold backup .Both these techniques come in handy to retrieve the data whenever the
