Executive Summary

There is too much data & it’s difficult to adequately protect.

There is a new WAVE…

Multi-Platform Disaster Recovery & Distributed Data Protection.

– The IBM z/OS Distributed Data Backup (zDDB) announcement is the start of a new era

of responsiveness.

– INNOVATION is delivering a new version of FDRSOS that combines with IBM zDDB and

FlashCopy (not tested by IBM).

– The result is the fastest, least disruptive and most efficient

z/OS solution for DS8700 multi-platform disaster recovery and distributed data protection

available today!



Part I: FDRSOS and zDDB



Background

� According to a Symantec Press Release edited by StorageNewsletter.com on Tuesday, July

6th, 2010 there are surveys that show 81% of respondents state data/storage growth is their

biggest challenge.

� Mainframe customers typically have very powerful backup / restore facilities, therefore such

customers could be interested using these facilities to also back up / restore Open System

data



Consider…this integrated solution

� System z mainframes can help meet enterprise goals of

“Consolidation”, “Virtualization”, and a “Green Data Center”

� Now there is something new to help:

– z/OS mainframe FICON access to DS8700 distributed data can help centralize multi-

platform data protection and cut backup time.

– Instant hardware replication can make backup non-disruptive.

– High capacity VTL and de-duplication appliances

can help reduce backup storage requirements.

� FDRSOS and zDDB (and FlashCopy)…are the New Wave.



How do we handle this…SIMPLE

– Consolidate distributed data protection…to a System z…moving backup data on high performance FICON.



What are we talking about?

INNOVATION & IBM Distributed Data Protection Solutions

� FDRSOS…z/OS Multi-Platform Disaster Recovery Protection for Distributed Data

� SOSINSTANT…Point-in-Time Disaster Recovery Protection for Distributed Data (not

tested by IBM (might be subject to future testing))

� UPSTREAM/SOS…z/OS Multi-Platform File Level Protection for Distributed Data (not

tested by IBM (might be subject to future testing))

� IBM z/OS Distributed Data Backup…DS8700 Facility Allowing Multi-Platform Access over

FICON Channels

� IBM FlashCopy…DS8700 Facility to Make Full Volume Point-in-Time Copies in an Instant



How do you implement this integrated solution?

� IBM zDDB is a new way to…– consolidate mainframe and distributed data protection.

– extend z/OS data protection to enterprise servers.

– move data on high-performance FICON instead of TCP/IP networks.

� INNOVATION FDRSOS is a new way to…– reduce distributed data disaster recovery backup and recovery times.

– conserve CPU resources.

– cut backup storage requirements.

– extend the value of z/OS scheduling, tape management & security.

� (INNOVATION SOSINSTANT is a new way to…– advance distributed data disaster recovery with IBM FlashCopy.)



IBM z/OS Distributed Data Backup (zDDB)

� Provides the capability to perform backup and restore of enterprise data residing on an IBM DS8700 Storage System over high-performance FICON connections. A multi-platform data protection solution that can help customers simplify their heterogeneous backup environments by consolidating and managing them through the mainframe.

� Idea: DS8700 recognizing / accepting FBA Channel Command Words (CCWs)



INNOVATION FDRSOS is a new way to…

� Extend z/OS data protection to Linux on System z, AIX, Linux x86-64, NetWare, OES2,

UNIX and Windows data on IBM DS8700 storage.

� FDRSOS and DS8700 zDDB…

can help you consolidate hundreds of Open Systems backup servers onto one z/OS

backup server running on System z.

� (SOSINSTANT with zDDB and FlashCopy lets you keep critical and revenue-generating

applications online without compromising information security.)

zDDB & FDRSOS® Works for…



Free up CPU resources











What is different with zDDB & FDRSOS…?

� A significant reduction in CPU time and much higher performance (Source: Innovation Data

Processing).

TCP/IP FDRSOS Comparison

Performance

MB/sec

< 50 +/- 100 FDRSOS is more than twice

as fast

CPU Usage

Millions of Instructions/GB

> 1400 +/- 100 TCP/IP take more than 14

times as much CPU



Easy to use – Simple to automate

RESTORE TYPE=FULL

FDRSOS restores a full-volume physical image of the entire Open Systems disk.



Defining zDDB Volumes in HCD…

� DS8700 zDDB disks are defined as 3390 but are NOT normal z/OS volumes.

� Mark zDDB disks as OFFLINE devices, so z/OS will not attempt to access them at IPL time.

� Attempts to vary DS8700 zDDB disks online to z/OS will result in error messages,

however…the devices will remain accessible to FDRSOS.

In HCD, the z/OS options for a zDDB device will look similar to this:

Device number . . : 01E0 Device type . . . : 3390

Parameter/ Value Req. Description

Feature

OFFLINE Yes Device considered online or offline at IPL

DYNAMIC Yes Device supports dynamic configuration

LOCANY Yes UCB can reside in 31 bit storage

ALTCTRL No Separate physical control unit path

SHARED Yes Device shared with other systems

Part II: Looking beyond FDRSOS and zDDB

� SOSINSTANT: Incorprating FlashCopy and

� UPSTREAM/SOS (file level backup)

These concepts have not been tested by IBM. They might be subject to future testing



Using FlashCopy (not tested by IBM (might be subject to future testing))











BreakTHROUGH Technology

IBM zDDB and IBM FlashCopy

FDRSOS and SOSINSTANT

– Instant Hardware Volume Replication

– Write Consistent Multi-volume…

– Non-Disruptive…

• Multi-Platform Disaster Recovery Protection for

Distributed Data



SOSINSTANT…Consistent Multi-volume…Replication

SOSINSTANT can create multiple point-in-time backups in parallel.

� Multi-volume point-in-time replication uses FlashCopy Consistency Groups.

� Stops I/O to all volumes in the FlashCopy Consistency Group [queue full].

� Creates crash consistent copies of multiple volumes at a single point-in-time.

FDRSOS defines a…FlashCopy Consistency Group

FDRSOS FlashCopy Targets…offline to application

Benefits using z Tape Management and Security











UPSTREAM/SOS® - Extends z/OS Multi-Platform Distributed Data Protection to File Level

� z/OS Multi-Platform Incremental Backup and File Level Distributed Data Protection for…AIX, Linux, UNIX, Windows & Linux on System z.

� All backup data travels on FICON channels.

� Only control data travels on the TCP/IP network.

� zDDB also extends FDR/UPSTREAM File Transfer.

� Not tested by IBM (might be subject to future testing)

UPSTREAM/SOS Data Flow, Incremental and File backup

DS8700



Apply Mainframe Resources to Disaster Recovery and Distributed Data Protection

� Using System z Backup Storage

� I.e. IBM TS7700 …..

� De-duplication – i.e. IBM TS7680 ProtecTIER.

� Physical Tape Library – i.e. BM TS3500

� Physical Tape – i.e. IBM TS1130

� Disk – i.e. DS8000

� Under the control of z/OS

� Auto-ops scheduling (i.e. IBM TWS/OPC…)

� Tape management (i.e. RMM)

� Data access security (i.e. RACF)



De-Duplication reduces backup storage requirements and improves media utilization

De-Duplication is a natural complement to Multi-Platform z/OS Distributed Data Protection.
