      You must backup!

 Presented by Dave Greenbaum
        We’ll cover
Why to backup.
What to backup.
How to backup
 How often
 On what?
 With what?
     Why to Backup:

Protection from
 1) Data loss
 2) Hardware failure
 3) Disaster
           1) Data Loss
Common reasons
 Accidental deletion
   Deleted a file and then realized you
   needed it
 Deliberate deletion
   Virus, Spyware, hackers
    2) Hardware failure

Hard drive wearing out most common.
Other common examples:
 Laptop dropped
 Spilled drinks
 General glitches and gremlins
3) Disaster

Fire-either caused by the computer or
near it
Water-especially in basement offices
Theft-laptops are most common item
stolen at airports
Loss-laptops are most common item left
on airplanes or security checkpoints
       3) Disaster

People think most about this, but protect
against it the least
 To protect against Disaster, you need to
 keep backups OFFSITE
   (More on this later)
        What to backup
Generally: Anything you create
Items often forgotten
 Saved passwords
 Fonts: can’t open a document without
 the right fonts
 On-line emails such as Gmail or Yahoo
    If you only backup one

Backup your Pictures, please!
  Digital photos have no negatives
  Photos are the hardest to recreate!
     What not to backup
Programs for which you have the
installation CD. Easier to simply reinstall
Programs that are downloaded and may
not be downloadable again should be
backed up
Operating system: easier to reinstall and
more reliable than your backup
  How often to backup?
Depends on how much data you are willing
to lose
Ideally once a day
During critical project times or critical
data, t wice daily
  Accountants during March/April good
How often to backup?

No backup will work unless you do it
Don’t be overly ambitious and then
abandon your backup routine
Backing up shouldn’t be burdensome and,
once set up, should only take a few
minutes of your time
       What to backup on?

 Usually best option for the casual user
   Generally hold about 4 gig
   DVDs give the best price performance
        Flash Drives
Very easy to use and relatively
Hold, on average, 8 gig for about $20
  compare to DVDs which hold 4 gig for
  about 50 cents
Generally better for transporting than
backing up or for specific backups
Moderately high failure rate
External Hard Disks
Can be expensive relative to DVDs, but
often are a good balance of speed and ease
of use
Great protection against hardware
Ideally you backup to multiple hard drives
and take offsite
     Soft ware Options

Many options, your choice should always
 Allow scheduling
 Record errors and notify you
 Very easy to restore data
     Program Types
Most are combos of
   Makes an exact duplicate of your hard
   Specify specific data to backup and
     Time Machine
Requires Leopard
 Makes an near duplicate of your hard
 Records changes
 About the easiest backup solution out
 Very Easy to restore from
Other Cloning Soft ware

   Most Popular
    SuperDuper ($28 for all features)
    Carbon Copy Cloner ($10 donation)
    Cloning Caveats
 Exact duplicate makes disaster or
 hardware failure recovery a snap
 Don’t need to reinstall anything
Disadvantage: Often need multiple large
hard drives
Comprehensive soft ware
  New Version came out in March
  Multi-year Beta program
    Personally, I’m not ready to use it
    Other Programs
Intego Personal Backup $79 or Prosoft
Databackup $59
 Includes cloning, backup, scheduling,
 synchronizing etc.
Programs very similar
 Can’t recommend Data Backup3
 Comes with OWC hard drives
    Other Programs
Less Expensive, but still highly
  Deja Vu: $25
  iBackup: Free
  CrashPlan: Free, but requires another
  computer to backup to
   Apple Backup App
Allows you to backup to CD/DVD, online

 Great place to start and may be
 adequate for many users
On-line backup services

 FWIW: Rush Limbaugh loves Carbonite
“Sync Services”

Drop Box (free for first 2 GB) and
SugarSync ($24.95/yr)

  particular folder to an online website
  Doesn’t work well with “iApps”, but great
  for documents
Sunflower customers!

Your are charged for how much data you
upload or download
Online services could cost you $5-$15 more
from Sunflower for your first month
Go to for
more info
            No longer viable
Zip disks
  Both drives and disks will fail and are
  no longer made
  Can’t hold nearly enough data
  Computers often don’t have floppy drives
Suggested E-Z System

If you have Leopard, use Time Machine!!!
 If you can afford it, get t wo drives and
 keep one offsite
Periodically burn backups of your iPhoto
and iTunes library from within the
 Non-Leopard users

If you have MobileMe, use space on their
ser ver. If not, use Mozy or Carbonite
Then use Carbon Copy Cloner/Super Duper
for cloning
Backup iPhoto/iTunes too
      Super Size it!
Go for the combo meal
Try to have at least 2 different backups
 Consider easy combos such as Time
 Machine and Mobile Me
 SuperDuper and Apple Backup
 Deja Vu and Mozy
So what do you do Dave?

Time Machine is primary
 Set to backup everything expect the
 System and program files
 Specific drive in my Mac Pro (internal)
Apple Backup backs up
Contacts, calendar, keychain 3x a day to
 My contacts and calendar are the most
 important thing on my Mac
Overnight, Apple backup backups up my
home folder to a external drive on our
net work

Backups all my work “DoctorDave” folder
 This makes it available on my iPhone
 and my PC as well as for my technicians

Copies my gmail accounts down to my
hard drive and then those files are included
in my overall backup strategy
Generally do this at the end of the month
after checking my Sunflower bandwidth
      Once a month

Use Apple Backup soft ware to burn DVDs
of my home folder
Take those backup DVDs to my office to
have an offsite backup
The next t wo points
are the most critical
   aspects of any
    backup plan...
       1. Take your backup
If a disaster occurs,
you need your
backup away from
the disaster, yet
still accessible
 Fire, water will
 destroy your
 Neighbors house;
 bad choice!
        By The way
“Fireproof” safes are generally protect
 Paper safes are protected against 350º
 Media melts at 125º to 300º
 Your cds will melt before your paper
   and ruin your paper too!
  2. Test your backups
A backup is no good unless you can
retrieve the data
Minimum of every month
Choose a random file to restore
For privacy purposes, destroy all failed
backup media
Do YOU know how to restore your data?
 If you forget to backup
...and have a data loss

Plan on spending on average $5,000-
$10,000 for a professional data recovery
ser vice
  Drivesavers and On-Track
The computer ate my homework is not a
business appropriate excuse
Any final questions?
