Abstract

This session will show the difference between Business continuance and Disaster recovery and how both can be achieved by using the different levels of protection. The first half of this session will deal with disaster recover and business continuance from a hardware and software vendor agnostic way. The second half will show how IBM/Tivoli can address the levels of protection. To wrap up we will cover some resources you have available to you with the IBM Tivoli Hardware and software.

AgendaDefinitions

– Disaster recovery

– Business continuance

– Levels of recovery

– Levels of data

Planning– Discover you data

– Rank your data

– SLA based Recover tiers

Putting it all together



DefinitionsWhat is disaster recovery?

–Disaster recovery is the process of recovering an environment after a major failure or disaster to the point at which business can be conducted

What is Business continuance?

–Business continuance is the act of recovering your environment while still being open for business. Little to zero downtime to affect the business transactions.

Business Recovery Options



Tier 0 - No offsite data

Time to recover is unpredictable - may be never

Tiers of Recovery

Standard data backup process, NOT DRM

Successful Disaster Recovery

A Documented Process for RecoveryUpdated and exercised regularly

A system environment in which to recoverHotsite; dedicated equipment, combinationIncluding a network environment

A protected repository for informationSystem, database, control, synchronization

Accurate, available, trusted data updatesDatabase software facilities play a key role

Skilled, experienced people to perform recovery

Planning

The key to any successful recovery is planning you must:

–Be prepared by know exactly what is on each computer and who owns the data.

–Be aware of what type of data you are restoring.

–Be secure that your data can be retrieved from backup media

–Be educated on what exactly you must do to restore the data

–Be able to verify the restore



Before your backup

Know your data

9



Why protect, store, and pay for……data that isn’t needed, used, or business-critical?

Remaining 10% capacity

Valid Data

Non Business Files

Duplicate data

Stale Data

Trash data, such as log files, dump files, temporary files

Protect this.

Archive this. Often

Clean this. Often

Delete this.

Delete this.

Get more of this.



Classify your data

Valid Data

Level 1 – Must have

Level 2 –Need to have

Level 3 – Should have

Level 4 – Don’t need

Important for backup and restore

How much data protection is enough for each of your computers?

15 Min. 1-4 Hr.. 4 -8 Hr.. 8-12 Hr.. 12-16 Hr.. 24 Hr.. Days

Tier 4 - Batch/Online database shadowing and journaling, repetitive PiT copies, fuzzy copy disk mirroring, TSM-DRM

Tier 3 - Electronic Vaulting, TSM

Tier 1 - PTAM*

Tier 2 - PTAM, Hot Site, TSMPoint-in-Time Backup

Active Secondary Site

Dedicated Remote Hot Site

t

Tier 7 - Near zero or zero Data Loss: Highly automated takeover on a complex wide or business-wide basis, using remote disk mirroring & data sharing

Tier 6 - Near zero or zero Data Loss remote disk mirroring helping with data integrity and data consistency

Tier 5 - software two site, two phase commit (transaction integrity); or repetitive PiT copies with small data loss

IBM Tivoli Storage Solutions in ActionServer & Storage recovery

Stage 1: Planning

Stage 3: Recovery • TSM: Backup, archive and restore / recovery

• SAN Mgr: Identify and troubleshoot new environment (RCA)

• SRM: Monitor storage, correct problems, forecast needs

Stage 2: Steady State • SAN Mgr: Monitor SAN, avoid / fix problems

• TSM: Move stale data, backup systems

• SRM: Track how the changes are effecting the environment

• SAN Mgr: Identify bottleneck and single point of failure

• TSM: Backup applications & critical data

• SRM: Analyze storage, identify critical / non-critical data
