Acronis miscalculates data on users' bad backup habits
The survey section where the percentages were taken out--the numbers just don't justify what Acronis said in its report.
(Credit: Acronis)Acronis, a major vendor of backup software, released a report earlier this week stating that about 87 percent of computer users back up their data once every two or three months--way less frequently than recommended. This suggests that most of us live dangerously when it comes to backing up.
The survey was widely reported in the press, but it turns out the numbers didn't seem to go well with Acronis' report.
The percentages released to the media were taken from the question "How often do you back up your hard drive or files?" Results include: 48 percent for "once a week (or more)"; 55 percent for "2-3 times a month"; 81.5 percent for "once a month"; 86.8 percent for "every 2-3 months", 91.4 percent for "2-3 times a year", 94.6 percent for "once a year or less"; and 25.5 percent for "never."
It may be that I'm Asian and extra good with math, but I couldn't help but notice that when added up, the numbers total around 500 percent. Other ways to interpret the chart didn't justify the reported 87 percent, either. So maybe you're not as bad at backing up as some media reports told you you were.
Marc Mombourquette, Acronis' product marketing manager, confirmed Wednesday morning that there was an error in the data calculation. He added that "in the future, we'll (be) restructuring the survey to allow only one answer and double-checking the total number of answers with the number of reported responses." In the meantime, the company is working on a revised report on the survey and the possibility of re-doing it entirely.
Preliminary recalculations by Acronis show that 64 percent of some 6,100 participants who answered the survey said they back up once every two or three months; 36 percent say they back up once a week.
Even with these new, more encouraging numbers, I still believe most of us don't take backing up seriously enough. Generally, if you use a computer frequently, it's important to back it up at least once a week.
Apart from True Image, a product by Acronis, there are also quite a few free and powerful backup products I recommend, such as GFi Backup Home Edition.
Remember, it's better to be safe than sorry, and you can never be too careful when it comes to important data (unless, of course, you're happy being a statistic).
Dong Ngo is a CNET editor who covers networking and network storage, and writes about anything else he finds interesting. You can also listen to his podcast at insidecnetlabs.cnet.com. E-mail Dong.
Eric Franklin's colleagues once had the following to say to him: "Eric, you've been doing this performance testing thing for over 10 years now. How about you try something different?" To which Eric responded, "How about you shut the #%$@! up?" This candid attitude
allows him to go toe-to-toe with the most extreme of personalities, including that of Dong Ngo. This bio was written by Eric Franklin.
Dong Ngo is a knowledgeable, opinionated individual who wants to convince the world that he's just a normal person; but he hasn't had much success. According to him, this is because the world itself is abnormal. Dong loves traveling and is well-versed in several languages. He, unfortunately, is not so well-versed in English. Still, it's best to ask him questions. From networking and how to optimize your system, to turning a strange place into home or what the meaning of life is…most of the time, he has the answers. The question is: Will he make himself understood? Subscribe and find out!
You are not reading the questions carefully. 94.9% back up once a year OR LESS, which includes Never. The 5.1% left over are the 124 people who skipped the question.
There is nothing wrong with the chart or numbers at all.
I'm not Asian, but I did go to MIT, which may be why I get it...
Your interpretation of "about 87 percent of computer users back up their data once every two or three months--way less frequently than recommended." is wrong also. What the chart shows is that about 87% of computer users back up AT LEAST once every two or three months, including the 48% who back up at least once a week or more.
In general, your entire article misunderstands and misinterprets the data and should be corrected. Not everyone reads comments.
But you later say "I couldn't help but notice that when added up, the numbers total around 500 percent." which makes no sense. These are cumulative percentages and are not meant to be added up.
I image my drive monthly because I also don't have a day or two to waste rebuilding my machine. Drives fail. It's in their job description. It's like musical chairs. When the drive fails, the game is over, and whatever you had is gone, gone, gone.
Math skills? Marketing people aren't hired for their math skills. More's the pity.
Unless they really wanted to say how many people in each bracket performed (or didn't perform) a particular backup type, which seems weird.
