Title: Disaster Recovery 2'0


1
Disaster Recovery 2.0 Presented by Bob
Graney bgraney_at_eaglerockalliance.com
2
Food for Thought
  • To go forward, you must backup.
  • Cardinal rule of computing
  • If it wasnt backed-up,
  • then it wasnt important.
  • The Sysadmins motto

3
Agenda
  • Realities of Disaster Recovery Today
  • Industry Trends / Statistics
  • Disaster Recovery Components
  • External Waves
  • Financial Tsunami
  • Going Green

4
Questions Posed
  • Disk based backup versus tape based. Do I still
    need tape?
  • Replication options host, network, application
    specific and array based solutions. Which is the
    right approach for my organization?
  • How can snapshots be used to improve recovery
    times?
  • Why is virtualization having such a big impact on
    DR strategies?
  • What infrastructure systems need to be self
    healing to ensure application recovery?
  • How do WAN accelerators fit into the DR strategy?
    Do they work in all scenarios (live replication
    versus replicating backups offsite)

5
DR Realities
  • Production environments have grown more complex
    with increasing availability requirements
  • 24 X 7 always on Internet apps
  • Work from home ? increased availability for all
    apps
  • Days of KO backup job _at_ 600 PM and send the
    tapes offsite the next morning are Going or
    Gone!
  • Manual business recovery workarounds are just a
    fond memory

6
DR Realities
  • Has your DR capability kept current?
  • Are you trapped in a tape based recovery
    strategy?
  • Are critical applications missing from DR
    strategy?
  • Does your test program validate recovery
    objectives?
  • Can you hit the defined RTOs?
  • Time for declaration, travel etc. included? Are
    they realistic?
  • Good mix of exercises across all critical
    applications?

7
DR Proclamations
  • Tape is dead Long live Disk!
  • Not quite dead yet but only disk for critical DR
  • Tape may be only option for single site and SMBs
  • Still needed for long term retention (archive)
    requirements
  • Also good for less critical systems with RTO in
    days/weeks
  • Infrastructure needs to be resilient
  • Recover AD better not be Step One of DR plan
  • Has the tape catalog been recovered at the DR
    site?
  • Work from Home has/will be the dominant work area
    recovery platform

8
The Need for Resiliency
A New Paradigm Has Emerged
9
Disaster Recovery Components
10
DR 2.0 Planning
  • It is the maintenance that kills you
  • How manual is your update process?
  • Do you have a tool or database in place?
  • Is there a current application / server map?
  • All applications or specific to certain data
    centers? Just in scope or just DR?

11
DR 2.0 Testing
  • Is there a documented Test schedule? Enforced?
  • Different examples of two tests per year
  • 1 mainframe 1 one distributed
    application
  • 1 big (almost all) 1 little (NetBackup,
    one DB)
  • 1 50 of apps 1 the other 50
  • Another approach
  • All apps with defined DR solution are tested
    every 18 months
  • Plans updated/enhanced as a result of testing?
  • Are walkthroughs done effectively?

12
DR 2.0 Data Center Availability
The Uptime Institute, Inc. has developed a four
Tier classification approach to facility
infrastructure functionality that addresses the
need for a common benchmarking standard.
Availability considerations on site
infrastructure should use this standard. www.uptim
einstitute.org/
13
DR 2.0
  • Migration from Hot Site vendors to Internal
  • Coincides with migration to DR replication
    solutions
  • Co-Lo facilities as part of Internal strategy
  • Outsourcing getting multi-faceted
  • Infrastructure support
  • Software as a Service (SaaS)
  • Cloud Computing

14
DR 2.0 Cloud Computing
  • It started with SaaS
  • Salesforce.com / LDRPS
  • Cloud vendors now looking toprovide scalability
    performanceflexibility
  • Vendors
  • Web 2.0 (Google, Amazon)
  • Traditional IT (IBM, MS)

15
DR 2.0 Cloud Computing
  • Cloud DR Considerations
  • Risk Profile has changed
  • Risk is diversified by moving app/data off
    corporate network
  • Negotiate/define DR SLAs in contract
  • Consider compliance requirements
  • Where is my data stored?

16
DR 2.0 WAN Accelerators
  • Who are the players?
  • Riverbed has mindshare Also Cisco, Bluecoat,
    Juniper
  • Types of environments
  • Branch to Data Center vs. Data Center to Data
    Center
  • Application Specific WAN Optimizers
  • Common apps are CIFS, HTTP
  • Also Oracle, SQL
  • Drivers to implementation
  • Data Center consolidation
  • Software As a Service (SAAS)
  • Branch environments

18
DR 2.0 Case Study
Wan Accelerators Eliminated Resynch
bottleneck Kept Bandwidth requirements
down Reduced data loss (RPO) Improved Recovery
Time (RTO)
19
DR 2.0
  • Work from Home Deployment
  • Supplement / replace fixed workarea recovery
  • Major Deployments
  • VPN
  • Citrix
  • Remote Desktop Protocol

DR 2.0 Recovery Tier Chart
1 Point-of Failure data protected to the time
of disaster 2 Intra-Day data protected
periodically during the business day 3 Last
Capture data protected via tape which is
typically last nights backup cycle
21
DR 2.0
  • High Availability Candidates
  • Directories/Authentication
  • Active Directory (AD)
  • Lightweight Directory Access Protocol (LDAP)
  • Network Routing
  • Domain Name Service (DNS)
  • Disaster Recovery Candidates
  • Firewall and other security devices
  • Data backup system

22
DR 2.0 Virtualization Defined
  • Virtualization is the creation of a virtual
    layer between the actual physical element and the
    virtual interface. The virtualization layer
    shields the user from hardware differences and
    masks changes to the actual element.
  • There are four areas of IT where Virtualization
    is making inroads
  • Network Virtualization Established technology
    including the use of VLANS, VPNs
  • Server Virtualization Great fit for DR/Test/Dev
    environments. Production also.
  • Storage Virtualization Gaining traction in the
    market. It is the pooling of physical storage
    from multiple devices into what appears to be a
    single storage device.
  • Desktop Virtualization The latest hot topic in
    this space. Tremendous potential to simplify
    workarea recovery, but requires network bandwidth.

Bottom Line Server Virtualization is a game
changer. Storage Virtualization is
just starting. Desktop is TBD
23
DR 2.0 Server Virtualization
  • 1,038 VMware customers from North America, Europe
    and Asia Pacific
  • 45 of respondents cited business continuity as
    main driver for virtualization deployment.
  • Server consolidation - 2nd most popular reason

24
DR 2.0 Virtualization
  • Server Virtualization
  • Vendors VM Ware, MS Hyper V, XenSource
  • DR Variations V2V, P2V, V2P
  • Primarily Windows moving slowly into Linux
  • Watch out for management issues

25
DR 2.0 Virtualization Case Study
  • International Manufacturing Company
  • Outsourced iSeries platform with RTO 24 hours
  • Windows environment with no DR capability

27
DR 2.0 Disk vs. Tape
  • DR of critical apps must be on disk
  • Tape adds too much risk
  • Tape means 1 to 2 days of data loss. Is that
    acceptable?
  • Cost differential between Tape / Disk is closing

28
DR 2.0 Data Replication
  • Replication options
  • Array based
  • SAN (also NAS)
  • iSCSI is gaining traction on Fiber Channel
  • Host (Server to Server)
  • Application specific
  • Oracle, Exchange, SharePoint etc.

29
DR 2.0 Data Replication
  • Replication vendors
  • Array based
  • SAN EMC, Hitachi, IBM
  • NAS NetApp, BlueArc
  • Host
  • DoubleTake, NeverFail
  • Application specific
  • Oracle, MS and others

30
DR 2.0 Data Backup
  • Advances in Data Backup Systems
  • Data De-duplication
  • 20-50x or more compression ratio often achieved
  • Continuous Data Protection
  • Snapshots

31
Surviving The Meltdown
  • Current financial environment will drastically
    impact us all.
  • What can the BCP / DR professional do about it?
  • Option 1 Hide in a corner and wait for 2010
  • Option 2 Get proactive identify cost
    effective solutions

32
Surviving The Meltdown
  • Tighten up plans
  • Identify Top Two Risks address them
  • Reallocate funds
  • Gap Analysis
  • Install saving technologies
  • Virtualization
  • WAN Accelerators
  • IP based replication

33
Going Green
  • By 2008, Gartner estimates that 48 of all IT
    budgets will be spent on energy alone.
  • The energy used to power the nations data
    centers doubled between 2000 and 2006, and could
    double again in another five years.
