Following on last weeks admission by one system admin where they deleted approx 1500 customer websites by running an errant script, even the big boys are not safe from maintenance problems, as the UK’s largest domain and hosting provider 123-reg has admitted that during a period of maintenance it has deleted unspecified number of its customers’ websites.
This gives me opportunity to talk about back up strategy, and also recommend our hosting provider Vidahost.
The company, which hosts 1.7m sites in the UK, said an error made during maintenance “effectively deleted” what was on some of its servers. In an email sent to customers on Sunday, 123-reg said it had “begun copying recovered VPS images to new hosts” and expected some websites to be restored overnight.
Do you have a back up strategy?
As a scuba diver I was taught that “two is one and one is none”, which basically means don’t rely on a single point of failure for anything that is critical, when it comes to a back up strategy we take this one step further to the 3-2-1 Strategy.
Three copies of your data, on two different mediums and 1 off site
An example of this would be a photo you have taken, one copy will be stored on your hard drive, another copy on an external USB drive and a third stored in the cloud with a service like Dropbox. The key in the model is the off site copy, in IT for Disaster Recovery we all look at the worse case scenario, so if your house burns down and you lose everything, at least some of your data is safe somewhere else out of the reach of the flames and the fire departments hose.
Of course, unless you have multiple data centers at your disposal part of this strategy relies on putting trust in the fact your data is safe with a third party, this is why we recommend Vidahost, we have used them religiously for a number of years (since 2002 in fact!) as their customer service is second to none, in all these years they have never failed to astound with their quality of service and speed of response, they also happen to be exceptional value for money.
There is no such thing as a perfect backup strategy, but the 3-2-1 philosophy is a solid start for the majority.
