Transcript of Oh My Goodness – Where’s My Data?

Data Backup, Storage, and Preservation Oh My Goodness -– Where’s My Data? What's in it for me? How valuable is YOUR data? If your data becomes unavailable today, how long would it take to re-construct it? Fallacy: You should only back up to paper because digital information will be unreadable 50 years from now. Wrong! First, today's paper, toner, and ink probably won't last 50 years. My photocopies made 20 years ago are now unreadable. Next, digital data is EASY to refresh and be readable for centuries.
Assuming, of course, that someone will be around to maintain the data. If your backup is more than 30 days old, THROW IT AWAY! How to make backups? There are many ways and the exact methods you use are probably not important. Just do SOMETHING! Having two simultaneous backups on two different media is the minimum.
Three simultaneous (different) backups is even better. Four, five, or six backups is not a bad idea. IT experts will always advise you that the backups should be stored in different places on different media. After all, a burst water pipe in your home may destroy your computer AND the backup that is stored nearby. Have local backups. Have backups stored "off site," preferably far away.
One backup is insufficient. You don't need to backup everything. In case of a major disaster, you can always replace operating systems and applications. What you cannot replace is your INFORMATION. Family photographs, genealogy databases, tax records, and more MUST be backed up in multiple places. My backup practices: 1. EVERYTHING is backed up to a one-terabyte portable hard drive that is plugged into a USB port on the back of the computer with the hard drive located beside the computer. New files automatically are copied with one hour.
2. All of my DOCUMENTS are also encrypted and backed up online to Backblaze.com (including all word processing documents, pictures, financial records, and more but not music files). New files are automatically copied within two hours.
3. All of my DOCUMENTS are also encrypted and copied automatically to laptop and to a PC at the office and to a different online server at DropBox.com. New files are automatically copied within minutes.
4. 20,000 MP3 music files are backed up to an iPod music player.
5. Selected important files are manually copied to a jump drive I normally keep in my pocket.
6. Once a month, I copy all of my DOCUMENTS to (encrypted) DVD disks that I take to the office and store in a desk drawer. I also throw away the month-old backup DVD disks. I have a MINIMUM of six copies of every file of importance plus the original files for a total of seven copies. Is that enough backup copies? Probably. How many copies of your important files do YOU have? Your backup plan does not have to be the same as mine. But you should have a plan! I suggest a minimum of two different backups, stored on two different types of media, stored in two different locations.
Three is better.
Four is better yet. Hardware You have many devices to choose from: Floppy disks (does anyone use these any more?)
CD or DVD disks (a bit slow to create but will reliably store data for one or two years)
Keep a spare hard drive spinning (my favorite solution)
Jump drives (but don't plan on long-term storage)
An online backup service (probably the most reliable backups of all) Software Point in Time backups versus latest files only You’ll always have access to the latest backup of your files, but previous file versions and files deleted from your computer are discarded from the Mozy data centers after 30 days. You have many backup programs to choose from Macintosh: use Time Machine
The best backup program I have ever seen
It's free and is included with every copy of OS X.5 and later Windows: dozens of backup programs to choose from The best backup program I have seen is BounceBack ($69 to $79) Creates a fully functional clone of your Windows system hard drive on external USB hard drive
Start-Up and Recover From an External USB Hard Drive
Automatically backup changes to your system with Continuous Data Protection (CDP)
Or Create Customize Preferences with Backup Scheduler
Data Saved in Native File Format - Immediate Access To Files
Backup data to Any USB Hard Drive, Secondary storage devices or even a Network Drive
Or to Multiple Destinations At Same Time
Secure Files With AES-256 Encryption
Maintain Point In Time “Versioned” Backups
Synchronize Backup Data Between Two Computers An impressive is Karen's Replicator (FREE) at www.karenware.com but does not make point in time backups. There are dozens of others, some free, some not. Quality varies widely. It's YOUR data. How much is it worth? Do you want to protect it?

Online Backups Prices range from free (2 GBto $5/month (50 GB) Mozy
Backblaze
Carbonite
The biggest cause of lost data
seems to be human error! Today's presentation is available at http://www.eogn.com/handouts/backups and,
yes, I have a backup copy.
