The Copy overkill

Capacity

Time Primary Data

Copy Data

Chart shows a growth

rate of 30%

Each byte of primary data

easily causes 25 bytes

of copies

Copies trigger 85%

of HW spending

Almost all copies sit idle


Do I need backup? I have storage cluster

Virus

Wrong patch

Admin or user error

Software error

80% of Unplanned downtime

goes along with data corruption

High Availability protects you against hardware failure,

but not against data corruption.

The Backup Reality

What will you do in case you need a backup?

Only 50% of SMBs make daily backups

Only 30% make VM backups

Death after a disaster: 25 – 45%

50% No backup strategy


Backup Considerations

A backup is a copy with a time stamp

How many recover points do I need? How much data loss am I willing to accept?

What is my Recovery Point Objective (RPO)?

How fast do I need my services to be available again?

What is my Recovery Time Objective (RTO)?

How disaster resilient do I need to be?

(how many remote copies do I need and how far away should they be?)

How much am I ready to pay for my insurance?

How many copies? At what location? On what media?


Are all those copies really copies?

Test/Dev: Copies

for temporary use

Applications are

primary data and

need protection

Archives are

primary data and

need protection

Content Depots for

analytics are copies

COPY?


Wouldn’t it be nice, if …

You would have exactly

the number of copies

you really need,

and only as long

as you need them?

Provisioning a copy

would be self service,

fast and easy?

All copies could be

managed centrally,

with one easy to use

GUI?


The answer

Data De-Duplication

and Data Protection

Infrastructure They are not all the same

Smart use

of Snapshots

and Replication

Concept wins

over tools If you don’t know your

Target, there is no

shortest way

to get there

Add use cases

Backup is important

Increase efficiency

Paranoia


You need Data Protection Infrastructure – but

Increase the ROI of your Data

Protection Infrastructure by

increasing the value

of your copies

Reduce your Data Protection

Infrastructure by creating just

the number of copies you need

Do you really need every

copy you generate today?

How much primary storage are

you using for snapshots? Any Flash?

How many copies

do you need off-site?

What else can you do with those

secondary copies of data?

Analytics? Enable test/development

without affecting production?

Could anybody else benefit

from read-only access to

a copy of the data?


ETERNUS CS Backup Appliances

Integrated appliance incl. backup SW

ETERNUS CS200c S2

Includes Commvault software and licenses

For disk backup and file archiving

Deduplication, replication functionality

ETERNUS CS8000

Unified data protection platform for disk, tape and cloud

Complete consolidation and virtualization of backup IT

Unmatched scale-out scalability up to 22 PB

Leading DR and HA technology

ETERNUS CS800 S6

Easy to use backup to disk appliances

Deduplication, replication functionality

Modular scalability

Target appliance SW independent


Checkmarks for Data Deduplication

Perfect HW configuration for highest performance at lowest cost

– Benefits of the Appliance form factor

Variable Bit Length – The most efficient way with superior Dedup factor

High Availability for Dedup – only with more than one node

Inline – immediate start of replication, use the full capacity

Is my data suitable for Dedup? (e.g. encrypted data is not)

Dedup as part of backup software (one vendor strategy) or backup software independent?

Capacity Medium Medium Large Largest

Speed Low High High Highest


But they

typically lack

It all starts with a snapshot

Immediately available

“version” of productive

data, very space efficient

Disk arrays are capable

of producing snapshots

A catalog – you soon lose control

Deep application integration

– without that, it is not usable for restore

Process automation – leads to OPEX issues

Independence of a single product

Write access – that is good enough

for back up, but not usable for test/dev

You get

all that

by adding

ETERNUS

Snapshot

Manager

(ESM)


Adding all that to array based snapshots: ESM

Create application consistent

virtual copies of data

Mount them from any server

for any purpose

Create a snapshot using ESM

These snapshots can be mounted from any server,

to be used for test/dev, analytics, etc.

DX supports read AND write on snapshots.

E.g. You could test an Oracle update before you go live

If you want to free the source DX, you can create a clone.

That provides highest performance

The snapshot can be accessed by any Backup Application

and can be written to any target (CS, cloud, S3, CD)

Near CDP: One snapshot every 15 minutes

Live test of retired applications possible


Two flavors of end-to-end copy management

Snapshot on DX,

triggered by ESM

Any Backup Software

reads the snapshot

and writes a backup

ESM + Backup

SW on server

To a target,

e.g. CS800, CS8000

ESM +

Backup

ESM +

CS200

Snapshot on DX,

triggered by ESM

CS200 contains ESM and

Simpana, reads the snapshot,

writes it to local disk and/or

replication target, cloud

Or a large target like CS8000


ESM/CS200 and ETERNUS CS8000

Commvault …

Why do I need a CS8000?

… uses a single index engine,

single pass data movement and

a single storage repository for

backup and archiving consoli-

dation singe pane of glass

copy management.


Purpose-Built Backup Appliance (PBBA)

Monolythic targets are single points

of failure. If one fails you can’t restore

its data. And they are performance

bottlenecks

Using a large file pool

at the backend. CS8000

ViNS provides such a

dramatically scalable and

fast pool. Single Media

Agent failures are no

issue any more.

Consolidating Copy management to a combination of Commvault and ETERNUS CS

Increase the efficiency of your Data Protection Infrastructure.

BUSINESS

BENEFITS

Better RPO, RTO, adding remote copies

for disaster recovery easily

One integrated environment for managing all copies,

including backup and archiving, replication and DR

Increase level of automation significantly,

increase productivity of highly skilled IT staff


More Benefits of Commvault + ETERNUS CS

Add value to your Data Protection Infrastructure.

BUSINESS

BENEFITS

Application retirement: free VMs from rarely used apps

Active Archiving: Free primary resources from rarely used data

Less DB licenses, reduced backup times, making archiving

cheap and easy

Developers have fast and easy access to real,

up to date data: better apps, faster available

It is fast and easy to test changes, e.g. patches and updates:

reduce risk of failure

Easy access to live data for analytics


Stechert Stahlrohrmöbel GmbH

„Fujitsu’s customer service is simply

better than the other providers.“

Maintain a permanent backup of the SAP database

Cope with future expansion (acquisitions)

DX + ESM + SEP + CS800

A consistent snapshot every 30 min.

“The main reason behind our decision to invest

in the Fujitsu ETERNUS technology was that it

enables us to quickly resume productivity

after an IT failure”, says Zimmermann, Head of IT,

Stechert Stahlrohrmöbel GmbH. “Before, we would

lose whole days’ worth of data, or really struggle to

find it. Now it is max 30 min.”
