Tech Tip – Keeping Your Data Safe
Note from the Author: I used to give a seminar on data backups when I worked at Stanford University . It was amazing to me how many scholars did not back up their data on a frequent basis! Out of 40 scholars in my department, a good 20% had come to me sometime in the year stating that they “lost their work” or that their “hard disk crashed”. Software and hardware are not perfect. Therefore, it is very important that you take steps to back up your data. Below is an excerpt from the seminar that I conducted. I (and all of us at Bradford Technologies), strongly recommend that you apply these tips in your computing environment.
Why Back-up Your Data?
Any one of the following can happen:
- Your computer is stolen, lost or destroyed in transit.
- Your hard disk fails or Windows spontaneously combusts.
- There is a power failure, and you did not save your work.
- You receive an email or web virus/worm, and it wipes out your hard disk or corrupts your files.
- You accidentally overwrite the latest version of your paper with an out-dated version.
The Backup Strategy
It is recommended that you always keep at least 3 copies of your work.
- Copies on your computers hard disk - Make it a habit of saving your work every 10 minutes or so. Store your files in a central location, such as My Documents(Note: In ClickFORMS, your Reports, Databases, PDF Files, Templates and other preferences are stored by default in My Documents \My ClickFORMS)
- Copies on a secondary medium - Since your hard disk can fail at any time, you need to have a copy that is not prone to damage - Periodically drag-and-drop files to the secondary medium
- A master copy that you can store in a safe place or at another secure location – For example, at the end of the day, save all your personal files to the medium of your choice and take it home with you
Ultimately, it is up to you to decide which backup program to use. Please use thoughtful consideration before setting up a backup scheme.
Scheduled Backup Programs - These programs allow you to specify a time and medium for backups. These programs can run simultaneously as you are working. Example programs include BackAgain, FolderClone, and Windows Backup (part of the operating system). You can find backup software at various software stores.
Manual Backup via various media - Requires a little more discipline. Essentially, you are responsible for saving copies of your files to a medium of your choice (e.g. Zip, floppy, CD, etc...).
Common Backup Media
Diskette (1.44 MB)
- Advantages = cheap, easy to use (drag/drop)
- Disadvantages = limited capacity, prone to errors
Zip (100, 250, 750 MB)
- Advantages = easy to use (drag/drop)
- Disadvantages = $$$, prone to errors
CD or DVD (~700 MB for a CD to several GB for DVDs)
- Advantages = convenient, lots of space!
- Disadvantages = CD format issues, more difficult
Portable Hard Disks (just as large as your internal hard disks)
- Advantages = portable, easy to use (drag/drop)
- Disadvantages = $$$, can crash like internal hard disks
Flash Memory Cards/Jump Drives (32 MB to 4 GB)
- Advantages = very reliable, universal compatibility, portable
- Disadvantages = $$$ but becoming much more affordable
Which is the Best Medium to Use?
Weigh the advantages and disadvantages of the various media listed above. For those of you who are a little more technically challenged, it's probably wise to stick with a medium that is drag/drop, such as Zip or Flash Memory, such as Jump Drives. CDs require some extra practice and additional software and hardware. You need a CD-Recordable drive on your computer to even begin. In addition, you need CD burning software, such as Roxio CD Creator.

Data Storage Safety Tips
- Always back up and test your back up! Keep current copies of important data offsite.
- To avoid data loss and program corruption, always exit your programs before shutting down your computer.
- All computer equipment should be used with high-quality surge protectors or line conditioners.
- Never turn off peripheral devices while the computer is on or when the disk is active. This may cause directory damage.
- Never reformat your drive without testing your backup. If you use tapes, be sure you are familiar with the backup software before archiving important data.
- Do not move or jar a drive while it is operating. When transporting a drive, prevent jostling by using a padded container.
- Allow adequate space around external drives’ cooling vent; remove books, papers, etc., which might black air flow. Do not put the drive on carpeting.
- As a general rule, if you are comfortable, the climate is appropriate for the drive. Avoid rapid temperature changes. If the drive was previously in a very cold environment, allow your drive to warm up to room temperature before operating.
- Use extreme caution when using software utilities – in cases of severe corruption or mechanical failure this may make the problem worse.
- If you hear unusual noises, turn off the unit immediately. These sounds may indicate a mechanical problem that could ultimately result in total data loss.
