2Food for Thought
- To go forward, you must backup.
- Cardinal rule of computing
- If it wasnt backed-up,
- then it wasnt important.
- The Sysadmins motto
3Agenda
- Realities of Disaster Recovery Today
- Industry Trends / Statistics
- Disaster Recovery Components
- External Waves
- Financial Tsunami
- Going Green
4Questions 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)
5DR 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
6DR 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?
7DR 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
8The Need for Resiliency
A New Paradigm Has Emerged
9Disaster Recovery Components
10DR 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?
11DR 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?
12DR 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

13DR 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
14DR 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)
15DR 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?
16DR 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
17DR 2.0 Case Study
International Law Firm Critical Applications MS
Exchange Files / Doc Mgmt Voice
18DR 2.0 Case Study
Wan Accelerators Eliminated Resynch
bottleneck Kept Bandwidth requirements
down Reduced data loss (RPO) Improved Recovery
Time (RTO)
19DR 2.0
- Work from Home Deployment
- Supplement / replace fixed workarea recovery
- Major Deployments
- VPN
- Citrix
- Remote Desktop Protocol
20DR 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
21DR 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
22DR 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
23DR 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
24DR 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
25DR 2.0 Virtualization Case Study
- International Manufacturing Company
- Outsourced iSeries platform with RTO 24 hours
- Windows environment with no DR capability

27DR 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
28DR 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.
29DR 2.0 Data Replication
- Replication vendors
- Array based
- SAN EMC, Hitachi, IBM
- NAS NetApp, BlueArc
- Host
- DoubleTake, NeverFail
- Application specific
- Oracle, MS and others
30DR 2.0 Data Backup
- Advances in Data Backup Systems
- Data De-duplication
- 20-50x or more compression ratio often achieved
- Continuous Data Protection
- Snapshots
31Surviving 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
32Surviving The Meltdown
- Tighten up plans
- Identify Top Two Risks address them
- Reallocate funds
- Gap Analysis
- Install saving technologies
- Virtualization
- WAN Accelerators
- IP based replication
33Going 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.
