Data Replication Strategies Stop production! It’s backup time The Bane of Business Disruption
4
Executive Summary Do not risk conducting business without a Business Continuation Plan… …employing modern data replication technology you do not need to stop business processing to back up data or to install the additional disk storage.
5
Overview What is Data Replication Technology? Why is it important? How and when did it come about? How can we use it? The Benefits…
6
What Is Data Replication Technology? Software and hardware for making additional copies of existing data…to improve data availability.
7
Why is Data Replication Important? Data Replication is a solution for protection against loss… Data Replication is key to improving data availability for Business Continuance.
8
How Improve Data Availability? Development and Testing –“Disposable” Copy for experimenting Improve Production Processing –“Duplicate” Copy for parallel access Business Protection / Business Continuance –“Backup” Copy as insurance against loss
9
Business Continuation… More than Disaster Recovery Apply Basic Principles Consider e-Business Requirements –24x7x365 Availability –Non-Stop Operations Employ Instant technology
10
Where Does the Pressure Come From? “e-Business extends direct consumer access to existing real-time business systems”
11
You Don’t Need A Disaster To Have A Disruption! Natural Disasters Site Destruction/Disruption –Fires, Power and Communications Failure Mechanical Equipment Failure –Processor, Disk and Network Hardware Software Failure –Operating System and Application Human Error –One Third of All Data Loss is Caused by Human Error Scheduled downtime… –Backup, New Equipment…
12
How Much Does Disruption Cost? Lost opportunity… –Securities Trading $6.5 million per hr –Intel Web Site Sales$275,000 per hr –Cable Home Shopping$113,000 per hr –Airline Reservations$ 89,000 per hr –Cellular Service Activation$ 41,000 per hr Fraud Exposure… Credit Cards $2.6 million per hr
13
WHERE IS THE DATA? Modern disk storage… Forty-five years old Thirty-eight years old Thirty years old Twenty-five years old
14
A Forty-Five Year Old Invention? September 13, 1956, the first RAMAC
15
Thirty-Eight Year Old Interconnections and a Thirty Year Old Controller..
16
Innovation Continued…! Disk storage capacity grew through the 1970s and 80s from 10 MBs to 100 MBs to 1000 MBs, gigabytes and terabytes…
17
A Twenty-Five Year Old Scheme Raid Structures 1978 IBM patent for Redundant Arrays of Independent Disks. 1987 University of California at Berkeley “Inexpensive” Disks
18
Hardware Didn’t Solve the Problem
19
Software Solutions Automated BACKUP AND RECOVERY Three approaches to backup Two reduce time by limiting the amount of data. One automates the solution.

33
How Can Data Replication be Useful? Data Replication is a strategic technology, to eliminate… Long interruptions for backup... Unacceptable recovery times… Production delays to copy data… Hard downtime to install new disks…
34
Impediments to Data Replication Being Useful Backup not on removable media Point-in-time hardware produce exact duplicates MVS does not allow duplicates online Conventional backup can not read offline volumes Re-labeling to bring volumes online destroys catalog access to data and means special restore procedures
35
Hardware and Software Working Together Non-Disruptive e-Business Backup Instant e-Business Recovery Backup/Restore Data Reduction Outboard/Host-Less Data Movement Install Disk Storage w/ no downtime Non-Disruptive Disk Load Balancing
36
Automate e-Business Protection INSTANT Technology Software Identify change files—Manage Backup Selection Use InstantTechnology Point-in-Time Disk Backup Provide Non-Disruptive Tape Backup Interface with Tape Management Systems Keep familiar offsite DR procedures the same Provide InstantRestore for onsite auto recovery
37
INSTANT INCREMENTAL A Backup Solution with Greater Savings Reduce Business Disruption with SnapShot, TimeFinder, ShadowImage or FlashCopy INSTANT Incremental is non-disruptive Non-Disruptive incremental cut tape usage half to 75%… Only backup what is changed
38
INSTANT INCREMENTAL is Easy! 1.Use InstantTechnology point-in-time disk backup 2.Record location of the InstantTechnology Backup - Restores are then immediately available 3.Non-Disruptively dump to tape from the InstantTechnology point-in-time disk backup …after the non-disruptive tape backup keep the InstantTechnology Backup disk for InstantRestore
