Common ExcusesI AM TOO BUSY – Today’s systems can be automated to the extent that almost
everything can be done without any kind of user intervention. Scheduled backups take the worry and the work out of the

I DON’T KNOW HOW TOBACKUP MY DATA – The choices are endless and
considerably simpler than in the past. We now have plug it in and the device takes over and does it’s job with NO INSTALLATION OR SETUP on the part of the user
Introduction
MY COMPUTER WON’T CRASH - Like tires on
your car, the electronic circuits your computer rides on will eventually wear down and blow out – 10% do.
When this happens, you can either grieve at your loss or simply restore your data with data backup software.

Elements of Backup1.Media Selection 2. Nature of the Data 3. Type of Application
Software Installed
Introduction
The SIX key issues to consider for a backup strategy: 1. Determination of Frequency
2. What type of Media
3. Determination of Source Data Integrity 4. Rotation of Backups
5. Verification of data backed up

Minimization of RiskNot an issue of if a matter of when
Why We Keep Backups
Why We Keep Backups – Disk
Crash
Best Defense: Redundancy
1. RAID – Redundant Array of Inexpensive
Drives - Replication of data amongst multiple drives – A system normally built into a server 2. Mirrored Hard Drives – A separate drive
system that most generally will be housed in a separate computer.
Why We Keep Backups – Disk
Crash
Reduction of Risk – Each instance of redundancy reduces risk of loss by 50% 174Why We Keep Backups
Why We Keep Backups – Total
Destruction
Best Defense – Location, Location , Location
In the event of a total destruction your only
defense is to be someplace else, i.e. data backup MUST include offsite storage
Why We Keep Backups
Why We Keep Backups – Theft
Most troublesome type of data loss:Data can be used for identity theft Affected clients must be notified
Data loss is roughly equivalent to disaster loss Very possible legal entanglements may be
outgrowth of occurrence
Why We Keep Backups – Theft
We defend theft of our equipment by: Physically securing computer equipment
Using STRONG (8 characters or more AND combination of numbers, characters, and letters (upper and lower case)) passwords
Encrypt data as appropriate – Do not use with MS XP does not deal with this well, however
Windows 7, Ultimate and Enterprise versions allow full volume encryption, perfect for our notebooks with sensitive data
Why We Keep Backups
Why We Keep Backups
Most likely threat – It has become accepted by most “experts” that almost every computer has some level of spyware, malware, trojan or virus resident on it’s system.
Critically speaking every computer (this
includes desktops and laptops) MUST be backed up with a clean backup.
There should be a regular process of backup of servers AND desktops
Why We Keep Backups
Grandfather, Father , SonA series of backups from
different periods – old school
Versioning
The ability to go to a particular date and restore the file to the condition as of that date
Why We Keep Backups
How far back do we go?Value of previous backups
Archive versus data restoration
How much room does it take and how much room do you have
Stability of media
Why We Keep Backups
1. Imaging Software can create a bootable drive that can be inserted into the machine with the failed hardware or can be maintained on a fully serviceable machine that can takeover the
responsibilities of the failed equipment.
Why We Keep Backups
2. Registry Files – Like the operating systemincredibly difficult to duplicate as the registry also represents the history of the machine
Options – Much like the operating system a mirrored machine will solve the problem the most quickly and easily. Resolve yourself to setting up a new machine and go on from there.
Why We Keep Backups
3. (Device) Drivers - The “driver” communicates through the computer bus or communications sub-system to issue commands to the affected device, this an range from printer to a USB port and ALL points in between.
Again a very machine specific issue that if you are restoring the originating machine the backup of drivers can be effective but even that can be
Why We Keep Backups
4. Applications – All of the programs that areinstalled on the computer to make it “our”
computer will come in the range of applications.
Dependent upon the level of use of the registry by the application, the more items written to the registry the more difficult to “restore”
Most applications work more effective post restoration if installed in normal manner.

computer will come in the range of applications.

PRACTICE POINTER –
Treat license information like you would data for disaster recovery – Store information off site or use lock box

Remote backup. Backups can take place across oceans, across town, or from one part of the office to another.
Remote deployment - Provision new computers to be backed up without having to go onsite. Send end-users a link to download and install the client on the device you want to back up.
Storage devices you control - Maintain complete control over where files and data are stored and protected by
backing up data directly to PCs or servers that you own or manage.

Media Selection – USB Flash
Drives
Exceptionally portable but easily concealable These devices can be security risks as a user can quickly copy files and hide the device in a purse or pocket.
Look for security software installed in the
device. Their portability makes them susceptible to loss as well.
Media Selection – USB Flash
Drives
Strengths - Small number of files backed up Transportable to alternate locations Concealment is easy
Weakness - Larger devices can get very pricy Concealment is easy
Media Selection – External Hard
Drives
Very good backup solutions as large as two terabytes and yet small enough to be easily transported.
Care should be exercised in handling as they can be damaged but with normal care will last an
extended period of time

Drives
Raw Data Rate - USB 1.1 – 12 Mbs - Dead USB 2.0 – 480 Mbs - Dying
USB 3.0 - 5 Gbs - Newest e-SATA 3.0 – 6 Gbs
Firewire – 400 Mbs
An e-SATA or Firewire connection may require the installation of a card on the machine. Most PC motherboards less than two years old have an e-SATA interface built in and a Firewire PCI card normally

Modern tape drives have significantly
Media Selection – Tape Drives
But lots of tape issues –Sequential access to data only – i.e. slow seek time for individual bits of data – accordingly works well for disaster recovery but poorly to
restore individual files
Moving tape (at a very high speed) over a stationary head (wear and tear is an evitable
outcome.
Media Selection – Tape Drives
But lots of tape issues –Data verification can be challenging Lack of compatibility across different equipment
The investment in tape cartridges can add up at $20 - $35 per unit.

Backup Software
Some Critical Features to Look for:• Wizard to assist in setting up backups
• Scheduler that will automatically complete backup at the appointed time
• Can backup Outlook Files – i.e. can backup an open file
• Backups can be password protected and/or encrypted
Summary
• 6% of all PCs will suffer an episode of data loss in any given year.
• 30% of all businesses that have a major fire go out of business within a year. 70% fail within five years.
• 31% of PC users have lost all of their files due to events beyond their control
• 34% of companies fail to test their tape backups, and of those that do, 77% have found tape back-up failures. • 60% of companies that lose their data will shut down
within 6 months of the disaster.
Summary
• 93% of companies that lost their data center for 10 days or more due to a disaster filed for bankruptcy within one year of the disaster. 50% of businesses that found
themselves without data management for this same time period filed for bankruptcy immediately.
• American business lost more than $7.6 billion as a result of viruses during first six months of 1999.
• Companies that aren't able to resume operations within ten days (of a disaster hit) are not likely to survive.
