Business Continuity
Some basic terminology
 Recovery Time Objective (RTO)
– How long after a failure can your business stand for an application to
be offline?
 Recovery Point Objective (RPO)
– When the application comes back online, how current does the data
need to be?
 Cost
– How much are you willing to spend on this insurance policy?

Remember that the
average Fortune 500
company has
something like 150TB
of storage…
Why Business Continuity?
Protect your business
 The Problem
Continuous
Availability
I have to buy duplicate
storage AND transfer
across some network
Cost
Rapid Recovery
Which data
goes where
and how do
I get it
there?
I have to keep duplicate
storage for all the
FlashCopies
Backup/Restore
I have to daily transfer
those TB’s across some
network and store
multiple copies on some
media

IBM Tivoli Continuous Data Protection for Files
Reduced or eliminate backup window
When a file is saved...
– A copy is stored on local disk
– Another copy can be sent to a
file server or NAS
– Another copy can be sent to
an IBM TSM Server
–Improve backup resource utilization
–Better ROI & TCO
Improved Recovery Point Objective
(RPO)
–Reduce loss of data
–Improved productivity

Improved Recovery Time Objective
(RTO)
–User initiated restore, zero administration
intervention
–Optional recovery from disk (local or remote)

Reduced Cost and Improved Flexibility
for Replication Services
Traditional Storage Hardware
 Replication targets must be the
same enterprise-class disk as the
source
 Cost of deployment can be
prohibitive for many clients
 Lower-cost disks offer primitive, or
no replication services
DS4000
 Common replication API
 Replication targets can be on lower-cost
DS4000 disks, reducing the overall cost of
exploiting replication services
