Security and your computer
Reasons to Back Up your computer1. Your digital photos are priceless
2. Your music library took you a lifetime to compile
3. Your brilliant thoughts—lost forever!
4. Protect your digital filing cabinet
5. You can take your laptop almost anywhere (but it’s not invincible)
6. Hard disks don’t last forever
7. Viruses, worms, and malware, oh my!
8. Disaster strikes
9. Data recovery is pricey and it doesn’t always work
Thanks to PC Magazine
Our Purpose
To create a copy of our private and personal information so that we can recover it regardless of the disaster that strikes.
Secondly, to return the computer to its working condition as easily as possible.
What should we back up?
In simple terms – everything,
but let’s be more specific
Where is this information stored?
3.5 inches
Some DefinitionsThe size of the filing room – or the
size of your hard disk is measured in BYTES
1000 bytes = 1 Kilobyte (KB)
1000 Kilobytes (KB) = 1 Megabyte (MB)
1400 KB or 1.4 MB• 1000 Megabytes (MB) = 1 Gigabyte
(GB)
Typical hard drive today between 200 and 500 GB
How information is stored in our computer (on our Hard Disk)
Windows XP,Vista
or 7
Programs Your Data
Supplied on a CD or DVD, or with some computers, a Restore Disk.
Word, Excel, Quicken, Firefox, Picasa etc., etc.Installed with computer when you buy it (and included on the Restore Disk), bought later on a CD or downloaded from the Internet
This is information unique to you – photos of grand-kids, your financial data, your emails and contacts, your music library etc.
• My Documents

External Drive back upHow to make it (almost) automatic
Windows includes a Back-Up Wizard
• Drives frequently come with Back-up software.
• If not, there are free programs that work well. I use Replicator, developed by Karen Kenworthy(http://www.karenware.com/powertools/ptreplicator.asp or just Google Replicator)
Windows Back-Up Wizard Click Start, then All
Programs, then Accessories, then System Tools and then Backup
This opens the Wizard
(Right clicking on Backup and select Send to Desktop will create a shortcut on the Desktop)

What about backing up the Operating System and Programs
Windows XP or Vista
Programs Your Data
• My Documents
• Favorites or Bookmarks
• Email and contacts
• Windows Back Up Wizard allows you to back up all the information on your computer
• Programs such as Norton Ghost and AcronisTrue Image enable you to create an “image” of your hard drive
How to restore your dataIf you get a virus, and your computer won’t boot, you may need to reinstall Windows.
If you have a Windows CD, and know the Authentication Code, you can boot from the CD and REPAIR Windows. This keeps your data and settings
If you have a Restore CD from your computer manufacturer, using it will return your computer to the state when it was new. All your data will be destroyed. You will also need to reinstall any programs that you have added.
My recommended Back Up Plan
My recommended Back Up Plan1. Divide the hard disk in your computer into two
“partitions”. This is like having two file cabinets –one for Windows and programs and the second for your data

2. Setting up the disk can be done when new or with programs such as Acronis® Disk Director ($50) or Partition Logic (free)

In SummaryThe three basic rules of “safe” computing
1. Install an Anti Virus program on your computer and make sure that it is updated regularly (automatically)
2. Install a Firewall on your computer and make sure it is always working
3. Update Windows regularly (automatically)

What Sex is my Computer – male or female
The men decided that the Computer is female because
No one but their creator understands their internal logic
Even the smallest mistakes are stored for ever for later retrieval
As soon as you make a commitment to one, you find yourself spending half your income on accessories for it
The women, however, believed that computers are male because In order to do anything with them, you have to
turn them on
They have a lot of data but cannot think for themselves
They are supposed to help you solve problems, but half the time, they are the problem
As soon as you commit to one, you realize that if you had waited a little longer, you could have got a better model
