43 percent of companies experiencing disasters
never reopen, and 29 percent close within two
years. McGladrey and Pullen

Business Continuity Protecting the Business

• Disaster recovery
• Planned and unplanned outages
• Planned outages
• Back-up of current applications and data for
  business continuity
• Implementation of new applications
• Copy of databases for application development

13
Approach Considerations

• Storage Based Replication
• Advantage of host software independence, no host
  cycles required, can be automated, can share
  network resources for cost relief, dynamically
  re-configurable
• Dependent on industrial strength storage platform
  
• Data Base Replication
• Advantage of integration into data base
• Consider complexity, administrative burden, only
  database replicated, distance between sites,
  transaction rates, database specific
• Host Software Replication
• Advantage of common approach
• Consider host MIPS, consider flexibility for
  return from contingency site, consider host
  software dependencies
• Tape
• Advantage is initial cost is low
• Consider time to backup, time to restore, effort
  to ensure backups are good, intensity of people
  time, long term management costs

14
Overview of Remote Replication

• Gold standard for enterprise business
  continuance and data replication with consistent
  procedures, products, and timing
• Server, operating system, and database
  independent
• Commercially hardened business continuance
  solution
• Multi-thousands of production implementations
  worldwide
• Maintain real-time, or near real-time, physically
  separate mirror of selected volumes
• Does not require host resources
• High performance for I/O-intensive applications
• Simplifies disaster recovery switch over and
  switch back
• Data replication for a variety of purposes
• Reporting
• Test beds
• Data warehouses

15
Mirroring Basics

• Mirror is a storage-based, real-time image of
  source data
• Serves as protection or another source for data
  reads / writes
• Logical volume with EMC tracking techniques
  associated

• SRDF/Mirrorview-specific mirrors
• SRDF/Mirrorview mirror is just another mirror
  over a distance in a second Symmetrix
• Only selected logical volumes are mirrored at the
  remote Symmetrix

EMC SnapView Parallel Information Access
Enterprise

• SnapView is a software product for the CLARiiON
  FC4700
• SnapView creates logical point-in-time views of
  production information

• Storage-based product uses no host cycles
• Takes only seconds to create a complete snapshot
• Snapshots can be created requiring only a
  fraction of the original filesystem space
• Snapshot allows parallel access to production
  data
• Snapshots are read/write mountable by a secondary
  host for increased productivity
• Minimizes time that production data is
  unavailable to users
• Eliminates scheduled downtime for backups
• Enables more frequent data warehouse refreshes

27
With SnapView You Win theRace to Sunrise
Enterprise

• SnapView is fast and non-disruptive
• Snapshots are created nearly instantaneously
• Active applications do not need to be taken
  offline for hours
• Creates a consistent point-in-time view for
  backup
• Daily backup windows are no longer needed
• S

• SnapView creates a separate mount point to the
  snapshot data
• Snapshot is immediately available for read and
  write access
• Backup servers can access the snapshot directly

  company?
• Which information systems and platforms support
  these processes?
• What is the value of the information that
  supports these processes?

  critical processes?
• How is the Business Continuity (D/R) plan
  maintained?
• Has your Business Continuity (D/R) plan been
  tested successfully in the last six months?

35
Recent Lessons Learned-Summary

• Data Mirroring Technology worked!
• SRDF failover was 100 successful
• BUTpeople and processes were not always in place
  to ensure application recovery and business
  resumption
• Vendor support personnel and capabilities are
  extremely important to a successful recovery
• In a crisis vendor support staff are critical
• Be sure to include them in building and testing
  your recovery plans

36
Summary-contd

• Dont forget to plan for ALL three major types of
  threats
• Physical
• Natural disaster
• Electronic
• Be sure your plans cover all three major aspects
• Data Recovery
• Application Recovery
• Business Resumption
• Never Enough Testing and Documentation

37
BARRON'S, September 24, 2001

• "Stock-market trading resumed last Monday, in
  good part thanks to the duplicate data storage
  allowed by the products of EMC."
• "If any technology product emerged the hero from
  the recent disasters, it was an EMC product
  called SRDF."
