You do have a backup of your website files on your own system (or elsewhere), right?

Oh hell yes. I don't edit on the live site for updating; I do it on the "master copy" on my laptop, and then publish it to both the main site at freelancetraveller.com and the mirror at freelancetraveller.downport.com. That's three copies in existence, so I should be able to recover if any one of them disappears.

But I do need to make a backup of the laptop...

I am afraid it is not exactly good news that they had to call in
the data recovery specialists. :shock:

as someone who works for a data recovery specialist, i'll just say they are in good hands..

i wish it was my company dealing with it, but as the server isn't in the UK its unlikely

I agree. Very emphatically. Among other things, it tells me that they had no provisions for off-site - or even off-line - backups; just on-site "live" backups. Not cool for mission-critical data. They say that they will have new procedures to manage backups in the future, but that doesn't really help right now...

You'd be surprised at how many data centres do not have a back up service.

I very much doubt that; I've been in IT for a variety of organizations for about 25 - or maybe closer to 30 - years, and the company that had the BEST disaster recovery plans - they were a provider of market data to brokerage houses - still had some gaping holes in their plan. Granted, the holes probably would only have been an issue in the event of a nuclear war, but I could still see them. To learn that data centers that DON'T warehouse financial system data also have major deficiencies in their handling of their 'mission critical' data (which may or may not be mission-critical to their customers) is not surprising; rather, the surprise would be if most of them DID have a credible disaster recovery plan.

Disasters are rare; the decision to have a disaster recovery plan becomes an exercise in risk evaluation vs. cost of the plan to implement. If you've theoretically set yourself up to maintain 95%+ uptime under normal circumstances, the cost of maintaining a "go-bag"-style disaster recovery plan may be too much higher than the value of the business warrants.

What surprises me most is that something as simple as a Faraday's
Cage (I hope it is called approximately the same in English) is often
not used to protect servers. Over here we had a series of cases
where lightnings caused serious damage to servers, one of my fa-
vourite forums was down for weeks and lost more than a month of
content because server and backup where in the same building and
not protected against lightning.

For lightning protection, a Faraday Cage is often overkill; instead, good lightning rods (ground rods) and surge suppressors on the power source are deemed normally adequate for such protection - and have generally proved to be adequate when flash came to bang.

Couple surge protection as above with off-line and off-site backups, and you really should be able to handle most crashes quickly and efficiently, with the acquisition of replacement hardware being potentially the most delay-causing factor in resurrecting a data center.

This may well be. Over here it would even have helped if a certain
provider would have understood that the tops of hills may be fine
for his cellphone arrays, but less than perfect for housing all his
servers in the same buildings.
