Since the days the early days of computers – the first one was invented in 1942 as a matter of fact – there have been concerns about the integrity of information storage on these devices.
In the 1970s, for example, I remember going to our local County Board of Education with my father, a school principal. I was amazed at the rows and rows of wall-sized tape recorders that he explained were the backups of all of the district’s school computers.
When dentists began using computers in the early 1990s for records, we started with simple “daisy chains” through which computers copied to other computers in the office to protect data. As needs developed, offices started to network to a central server that was the “brain” of all of the practice’s computers. To protect the information from crash or catastrophe, the first backups were simply data copied to a series of floppy disks. When the volume of digital data grew to levels in which it took too much time to have someone sit there at the end of the day and keep feeding disks into the computer, tape backups were developed. Today, most computerized offices have converted to portable hard drives instead of tapes because they are more convenient, easier to use and appear to be more durable.
Notice I wrote “appear to be.” According to DataMountain, an online data backup service company, there are some interesting – but alarming – facts about backups (http://datamountain.com/services/livevault/tapes-fail/):
- Microsoft found that 42 percent of attempted recoveries from tape backups in a recent 12-month period failed. Further, Microsoft’s former group product manager for the company’s Data Protection Manager, said, “More than 50 percent of customers we’ve surveyed said their current backup solutions do not fill their needs.”
- A report by Storage Magazine (storagemagazine.techtarget.com) found that more than a third of businesses do not test their backups. Of those who do testing, more than 75 percent have reported failures with recovery.
- In a survey of IT managers, Yankee Group and Sunbelt Software found that 40 percent of them had been unable to recover data when they needed it.
- The Gartner Group (www.gartner.com) found that 71 percent of all tape restores fail.
Furthermore, a 2011 survey conducted at the national Data Center Conference found that 70 percent of data backups are never checked for accuracy. The same survey also found that 30 percent of tested backups are corrupt.

So, why do dental record keeping backups fail from 30 to 50 percent of the time? There are many factors, from power surges and power interruption to human error.
Human error is inevitable and cannot reasonably be eliminated. To understand human error, have you ever been grocery shopping at a 24-hour grocery store at midnight? At midnight, the registers have to be completely shut down for 15 to 20 minutes, leaving anyone standing in line with melting ice cream. Why? Every computer workstation (including cash registers) must be completely shut down in order to ensure the backup is not corrupted.
Bringing it back to the dental practice, I’m sure that none of our dental staff members – and, of course, no dental practice owner – ever leave an application of our dental software open in an operatory or in the assistant work area while the backup is being created, right? If so, the backup is likely corrupt for that day on some level.
If you’re using a standard HIPAA-compliant dental record keeping backup system, the take home message is simple: Make sure everyone knows when the backup will be created. Also, make sure all the computers on the system are closed out, including all backed-up applications, before creating the backup.
