Low cost Data Protection concepts for Virtualized environments

February 7th, 2010

Given the widespread success of virtualization, many SMBs rely exclusively on the inbuilt features as their main data protection plan and which may appear adequate at face value! One would need to see the overall picture! Virtual server based tools such as, snapshots and export/import utilities that are found in the major products, help organizations protect their data to a certain degree! It is not enough to backup data, being a clone or a file to the same virtual server. In fact, major manufacturers and their fellow partners provide a vast range of backup solutions that fulfill all requirements of a proper backup policy. With SMBs, the deciding factor may be costs! Do they have the budget to purchase such applications? However, for the unlucky IT techies that never manage to get their superiors buying these expensive products can still develop a similar mechanism. Using some basic scripting and inexpensive hardware they can build backup solutions similar to these expensive applications as they too, make use of the inbuilt or native tools found in the major virtualization products.

Are online backup and recovery solutions cheaper than the counterpart traditional solutions? Before I deal with this argument I would like to point out a few points: – online backups provide an offsite disaster recovery solution, you can access your data from anywhere given that you have an internet connection and additionally, you will be enjoying the expertise and the scalability of big vendors.

Online backups offer cheaper costs per GB for the same functionality because you only pay for what you use. :) The costs include the storage used, bandwidth consumed and other related services. Data security is based on the latest encryption algorithms and adequate auditing features would place the end-user’s mind at rest!

Typical Backup Destination Media for Home Users

January 11th, 2010

Internal hard drives: Hard drives are relatively inexpensive and efficient but they are prone to viruses or software corruption due to other software running on the system. You can’t store it in a location separate from your computer. You have to install it in another computer in case you have problems with the computer and you need to recover the backed up data.

External hard drives: An external hard drive can easily be attached to your computer using a USB port. External hard drives can be stored in a location that’s separate from your computer, which can help protect your backup. You need to connect it with your computer every time a data backup is done and is usually slower than internal hard drives. Read more »

Wish You and Your Dearest a No Data Loss Year

December 31st, 2009

I want to take the opportunity to wish you and your dearest the very best for the forthcoming year. Some places are already referring to the newly hung calendar while others have a few more hours to go before their 2009 almanac would have served its purpose.

Health, good fortune and prosperity are the common form of wishes we bestow upon one another. And since I do not want to break with tradition I would like to bestow them onto you. Yet with all of these there is little we can do to determine the outcome. What destiny has in stock for each and every one of us will be revealed at the appropriate time. Some of the wishes can be even considered to be dangerous. For example I would never suggest to a friend to take on gambling so as to increase her prospects of getting some good fortune.

Yet I can safely wish you a year without any loss of data. The simple trick is to backup your data regularly, ideally in a manner that is automated and does not necessitate you having to remember to do it. If the process is automated there is a great chance that you will succeed in not losing any critical information if your computer takes all the data with it when it dies out.

Are online backups for your computer a safe idea?

December 23rd, 2009

Are cars safe? Are computers safe? Is buying over the internet safe? These are some of the questions people who pose the question above might have asked a hundred, thirty and fifteen years ago. Today, many of us use cars, computers and regularly effect payments over the internet without much thought. When talking about online backups, the simple answer to the question being asked is yes.

The Computer’s First Backup

December 9th, 2009

As soon as computers came into existence they started breaking down; and breakdown they did. The early computers used vacuum tubes and would break down roughly every other day. The absolute majority of problems related to failed vacuum tubes although with so many mechanical parts, there were other breakdowns that would need addressing albeit comparatively much less frequently.

Why People Don’t Take Backups

November 20th, 2009

Originally I had intended to call this article “Why My People Don’t Take Backups” but I didn’t want to give the impression that people call me El Presidente. My people are individuals who I meet when giving office productivity training. Normally this training is conducted over five half afternoons with a half hour tea or coffee break. I feel that breaks are critical towards rapport building. I find that after the first or second break sessions, shy people have a greater probability to open up and participate more during class sessions. People who are afraid of asking a question for fear of making a statement that will be so utterly stupid that everyone else will ridicule them, will, during a break session, ask their question in private and get an answer to something that has been keeping them from using the product to complete a task they regularly perform. For many, these sessions constitute a time to ask questions related to computing in general and by the third day questions originating from spouses or children are floored. On my part, break sessions allow me to get a better understanding of what people use the office product for and their general level of computer literacy. I need to clarify that break sessions are also a time for chatting about a multitude of topics that would have made the headlines as well as a time to move away from the computer.
My people are working individuals who have completed secondary education but who, in their majority, have not necessarily attended university. Some of the people take or have taken some sort of adult education training besides this training. Many have a home computer which they share with at least one other person. The absolute majority of people who have a computer at home have an internet connection. Most of their online time is spent on email, on social networking sites and chatting. Watching internet TV, reading online newspapers, buying stuff as well as participation in some sort of virtual world are other activities people get involved with. If a member of the family is still in school, the computer would be used for school-related assignments.

Over the past few months I have been trying to educate myself on the topic of backups. So during one or two breaks I would try to get answers to the following questions:

  1.  Have you ever lost data on your computer?
  2. Do you know what a backup is?
  3. Do you regularly take a backup?
  4. What would be your ideal backup solution?

Have you ever lost data on your computer?

Many people reply yes to this answer. In a number of cases, the loss is related to a genuine hard disk failure. On the other hand I have been told stories of computers being wiped clean without taking a backup first simply because the computer would not boot Windows or to remove an insidious Malware infection. In many such cases, I learnt that the computer owner is a self-made computer technician who has just graduated the 101-Format-and-Install-Windows-from-scratch course—and knows nothing else. Others would have taken their computer to their son’s friend or to some amateurish setup that seem able to eradicate the problem only if they format the computer. Sadly no one ever bothered to make a copy of the My Documents folders on the problem computer beforehand!

The stuff lost normally always includes digital photos. On those computers in which at least one of the users is in school, such a loss is associated with lost assignments (sometimes very critical). People also mention emails as being something they severely miss after a loss. Although not as important as the other items I have mentioned, a lot of people find that re-entering ISP settings, setting up printers and other devices, remembering web site addresses and passwords and the process of making a computer function as it did before the event is a hassle.

Do you know what a backup is?

Everybody knows that a backup is a process in which important files are copied to a separate medium just in case the computer breaks down or one deletes a document by mistake. The majority of people know that they can backup their important files to CDs, DVDs or USB sticks. Few people know whether their operating system comes bundled with a backup program and fewer people can mention by name a company that sells a backup solution or at least the name of the backup program itself.

Do you regularly take a backup?

Less than five percent of the people I have spoken to claim that they regularly take a backup. My definition of regular for the home user would be at least once a week in those quite periods, at least daily during that time when the user is using the computer for a critical task. I would consider critical any of the following situations: a thesis or project that could pass or fail a person or that could increase the person’s overall score; a work related project that may be mentioned in a performance review; a task assigned by the voluntary group the person is associated with that is important for the group; any home related part time work that is done on the computer; any photo or sound clip of a person or persons covering a past event; any document that is currently being updated and into which one has put months and years to create and which, if lost, would probably never be recreated. I need to point out that this short list sums up many of the stories of data loss I was told by my students. Many of those who have performed a backup use the Windows Explorer program to drag files from their original location to the CD or DVD icon or to the USB drive. Issues related to media spanning or a single file being larger than the media on which it is to be backed up constitute an issue for many. In the case of the latter scenario many people simply do not back up the file. I once had a student who told me that she would back up her files onto a USB stick but would erase the USB drive every time she needed the gadget for something else—not the best backup strategy around!

The remaining ninety five percent of people do not take regular backups or have never done so. The group that has never taken at least one backup tends to be those who have never suffered a data loss. They tend to be relative newbies to the world of computers. The impression I get from speaking to people who have taken at least one backup is that backups are like New Year resolutions; a lot of drive and determination at the beginning that fizzles out over time. Taking a backup tends to be bound either to a recent data loss or to the energy and drive that normally accompany the beginning of an important project that demands the use of a computer.

What would be your ideal backup solution?

From the hundreds of people I have spoken to on this subject I have come up with the following definition of what an ideal backup should be.

A Backup should be a solution that is easy to setup. When I open the program it gives me a Windows Explorer-type list that allows me to choose the directories I want to backup. The backup should be over the internet so that I do not have to fiddle DVDs and CDs. The backup solution should work in the background monitoring my selected directories and should automatically backup changed files without any involvement on my part although it should have an icon on the desktop which when clicked will run the backup manually. The backup should keep files I delete for at least 7 days just in case I deleted a file by mistake.

If something happens to my computer and I lose everything, I want to be able to install the program again and after typing in my username and password, the program automatically downloads saved backup setting so that I do not have to recreate them. I want to have a Restore icon on my desktop that, when clicked, will allow me to restore individual files, complete directories or deleted files. The interface should be similar to Windows Explorer.”

Meet Troy

October 12th, 2009

You may not know Sgt Troy Dally; you probably never attended Pastor Michael Guisande sermons; Cassie Bond is probably not listed as a friend on your Facebook, MySpace or Hi5 page and 21 year old Mark Leatham rings no bell. These are four people who have had their computer stolen. Troy’s laptop computer and external hard disk were in a backpack that went missing; Pastor Guisande’s computer was stolen from his church; Cassie and Mark suffered a similar predicament.

MeetTroy

These people did not have any military sensitive information on their computers; they didn’t even have the personal details of members of their local soccer club or church choir. They didn’t make the headlines because the value of their desktop or notebook computer was gynormous. Pastor Michael lost 20 years of sermons;  Troy’s laptop and external hard disk contained photos he had taken while serving in Iran as well as digital images of his house which burned down while he was away in Iran; Cassie’s home computer held the last photos she had taken of her dad before he died; Mark’s notebook contained the last photos of his mum who died after suffering from a rare degenerative condition called Pompe disease.

It’s not the cost of replacing the computer that bothers these people; some have even stated that they would be happy to get the contents of their computer back and have promised that if someone hands them a DVD or the notebook’s hard disk with their personal stuff they would not ask any questions. Their personal stuff is worthless to anyone else. Cassie summed it up by stating that “It’s really distressing to know that someone could just wipe all that off and sell it for money”.

These are four of the hundreds of computer thefts that take place every day of the year. These people don’t live in a bad neighborhood; they come from Australia, England, United States, and every country that has computers and crime. Had these people had a Remote Backup solution they would not have found it necessary to become one of the pages of a newspaper. A Remote Backup account allows you to backup your important files over the internet at lightening speed. The number of backups one can take is unlimited. Irrespective of whatever happens to the computer sitting in your backpack or on a desk at home, your data will never cease to exist. Remote Backups turn a disaster into a minor inconvenience.

In a connected world Remote Backups are something we cannot live without.

Uncle Bertrand and Auntie Lucy

Help your photos make it to the next generation - Take a backup

Last week I decided to unpack yet another box I had carried over to my new house almost a year ago. The thing with the last remaining boxes is that these contain the non essential bits and pieces, the memorabilia and stuff that was either passed down to me or which was prevalent in my life many years ago. Opening these boxes isn’t an act of simply unpacking and sorting stuff but one of reminiscing through my and my ancestry’s past. This box contained photos taken during the 60s and 70s. And I always thought that only punk rockers had funny hair styles!

Up to the advent of digital photography, taking a photo was a costly process. Even though one could purchase relatively cheap cameras, the cost of film and the development of the same were such that taking a photo would be a planned event for many people. Since each photo carried its own cost, a photo would be discarded only if it was horribly wrong. A photo with half of Aunt Lucy missing or Uncle Bertrand being slightly blurred would be retained and would be passed around on those infrequent family gatherings when old photos would be passed around.

Today we live in the digital era. Ones and zeroes have replaced paper and chemicals. Cameras are cheap and even the cheapest models have sufficient functionality built in to make anyone a respectable photographer.  It is becoming impossible to get a blurred, overexposed or underexposed photo. Who knows, someday we will be asked to pay for some of these retro functionalities! Now-a-days when taking a photo we keep on recording one shot after another until we get the one we are happy with. All we have to do is delete the ones we do not want and eventually transfer everything to a folder on our computer.

Yet will a digital photo of Uncle Bertrand taken today be available to someone in 40 years time? The answer is a probable no. Your hard disk in your home computer will fail sooner or later, the notebook on which you keep all your photos will suffer a fall, get stolen or lost and maybe a virus or component failure will wipe away all the data on your computer. Even CD and DVD-ROMs have a shelf life after which the manufacturer no longer guarantees the readability of data.

Taking regular and repeated backups of your computer’s important files is the only way to ensure that someone will be able to comment on your hairstyle somewhere down the line. Fast online backups to offsite servers ensure not only that you are backing up the things that matter to you but also that you are safeguarding against losses as a result of fire, flood, and theft.

Go on, let others have a good laugh at you – protect your data by taking a backup.
