What is the gap?

• Many small and medium sized business (SMBs) do
  not have sufficient data recovery plans and
  procedures in place
• Many large businesses dont either!
• Studies show that as many as 70 percent of
  businesses that suffer major data loss are out of
  business within a year
• Recovery after data loss is harder for SMBs
• Limited staff/expertise
• Limited financial resources to sustain loss of
  business
• Limited financial resources to deploy
  enterprise-class (Fortune 100) computing
  environments
• Costs can easily be in the millions

Why is data lost?

• Data is lost in many ways
• Hardware failure the failure rate of all
  hardwareis 100 -- eventually, everything fails
• Software error/corruption
• Human error no way to prevent this!
• Malicious attack virus, hacker, terrorism, etc.
• Environmental disaster fire, flood, burst pipes,
  etc.
• Power failures increasing as old power grids are
  overwhelmed
• Equipment loss/theft a great deal of business
  data is now on laptops which are routinely stolen
  at airports, hotels, etc.
• Laptops can be damaged in car accidents, dropped,
  etc.

How to begin?

• Ask the hard question if I lost all my data
  today, how sure am I that I would get it back?
• Do you feel comfortable thinking about this?
• The question is not what are you doing to protect
  your data, but what do you do when you need to
  get it back?
• Backup is meaningless if restore doesnt work!
• Understand your own needs
• How quickly to I need to be back on-line?
• Instant recovery can be achieved, but is
  extraordinarily costly
• Can my business sustain one down day? two days? a
  week? or only hours?

How to begin?

• Tape backup is the most prevalent SMB way of
  protecting data, but how safe is it?
• When was the last time you tested a restore?
• Are your backups getting done every night?
• How much impact will losing a day of data cause?
• Last nights backup doesnt have todays data!
• Again when was the last time you tested a
  restore?
• Are your tapes in good shape? Or old and worn
  out?
• When was the last time you tested a restore?
• Always keep in mind the only thing you cannot
  replace is your data
• Any hardware can be replaced, but once data is
  lost, it is lost forever

Looking at solutions

• Start thinking about SANs and virtual storage
• Yes, you can afford them
• Start thinking about duplicating data on disk
• Disk prices are lower than ever
• Start thinking about off-site replication
• Doesnt have to cost a fortune
• Start thinking about new ways to do tape backup
• Moving to a SAN will help

7
SANs

• Centralizing data storage provides easier
  management and increased protection
• Virtualized storage makes storage provisioning
  and protection simple
• Costs are not prohibitive!
• The SMB does not need to look for enterprise
  class solutions that cost high six- and
  seven-figures
• Entry-level storage solutions provides tremendous
  price/performance benefits well within reach
• Dont think of SANs as Fibre Channel only
• IP-based SANs are a reality today
• Use your existing infrastructure, cabling, staff
  expertise

8
Duplicate Data on Disk

• Use data mirroring to keep two copies of data up
  and running at all times
• Immediate protection from hard disk failures with
  zero impact on applications
• As drive sizes increase, more data is lost with
  each failure!
• Data should be mirrored to separate disk devices
  to protect from device-level failure or user
  error
• Incremental cost of more disk is relatively small
• Fibre Channel disk enclosures can be located in
  separate locations for protection from localized
  environment mishaps

Sample SAN deployment

• Typical SAN environment

Application servers support for multiple
operating systems
Switches Fibre Channel or Gigabit Ethernet -
your choice!
GigE or FC
Storage virtualization appliances for management
and data protection services
Dual storage devices for mirrored data and
physical separation
Virtualized storage for ease of management
10
Offsite replication

• Protect data on disk for more granular protection
  and easier recovery
• Make use of second sites to hold data
• Each site can replicate to the other
• Replicate branch offices to central site
• Avoid tape handling at multiple locations where
  expertise may not exist
• Asynchronous replication modes do not require
  tremendous amount of bandwidth

11
Offsite replication - host based

• Software resides on each server
• Data is copied to other server or storage
  appliance
• Advantages
• Easy to deploy
• Uses standard IP networks for data replication
• Does not require SAN infrastructure
• Replication to central appliance allows for
  consolidated backup
• Challenges
• Must be managed at each server
• Different products for every operating system

replicated data, and central backup pool

Offsite replication - network based

• Software resides in the storage network on
  appliance
• Data is copied from one storage appliance to
  another
• Advantages
• Single point of management
• Supports multiple servers from one device
• Single product for all operating systems
• Uses standard IP network for data replication
• Challenges
• Requires a SAN infrastructure

Tape backup

• SANs simplify tape backup procedures
• Backup for all servers is centralized
• Leverage single tape library, instead of multiple
  tape drives
• Virtualization appliance eliminates need for
  costly SAN tape backup options
• Run image-based backups directly from storage
  appliance for fastest backup possible
• Run file-by-file backup from standalone backup
  server using data snapshots
• Both methods are serverless and have no impact on
  operations

16
Conclusions

• Seriously evaluate your disaster recovery
  policies
• Do you feel your company is safe with your
  current plans?
• Consider alternative methods
• Less expensive than you might think
• Less complicated than you might think
• Much more important than you might think!
• Your first major data loss is likely to be your
  last
• Dont fall through the gap!
