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.

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.

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
