The trend in computers is to store all your files "in the cloud." That doesn't mean they're up in the sky, they're in a big hard drive somewhere. But that got me wondering: How secure is the cloud? Are we one good case of sunspots or an electromagnetic pulse away from losing it all?
One problem is the term 'cloud.' It suggests that core computing resources — not just storage but also processors and communications infrastructure — reside in some unknowable realm, like Valhalla or the quantum foam. This is rubbish, as you know, the stuff lives on physical machinery. However, it’s not just 'a big hard drive somewhere.' Rather, copies of your data presumably are distributed among multiple servers in widely separated locations, so no single disaster can destroy it or render it inaccessible.
What do you think about saving stuff on 'the cloud'?

Good points raised Rob and no not paranoia, I have intended backing up my system drive and storing it elsewhere for a while.
Will get onto that later today now you have reminded me, I wouldn't mind building my own NAS server too, so I can have my own cloud on my own server.

The main problem till now seems storage reliability. It may sound nice to be able to sue a company if it loses your data, but that doesn't really help much when you rely on the data being available.
For private persons, well some aren't too good at protecting their own data anyway. How many of you have photo's which start to show funny colouring schemes? How many have data on media they don't know how to access? How many here make a regular backup of their private stuff? How many put the backup in different physical location than the original / current data?
For me? I'm in IT, I still have data from 1988 in readable format, oldest email from 1993 I think. I normally make a scan of important papers and documents. All this probably makes me a bit of an exception

I backed up a lot of stuff on a couple of cloud sites some 3 years back around 5 G if memory serves me correct both those sites have vanished into the Bermuda Triangle of the cyber cosmos with my content. Nom big deal aas it wa in the main snippets however there was a some good music there. My preference is for a decent external drive(1TB) where all is backed up, I also use Google Docs, Sky Drive/One Drive, Drop box and A drive.Photo Bucket and Picasa have a lot of stored images. I do need and like the ability of being able to access any content I may need from wherever I am and perhaps I don't have the info needed on a USB or any other device with me at the time, on line I go and 'Hey Presto'' there is that which I seek All the sites do seem to have survived and have to date served me well, I am of the mind it is better to stick with sites with a good reputation and certain restrictions and slower upload speeds backed by the industries giants as opposed to wonderful offers from gimcrack sites that seem to spring up quickly and only vanish a little slower than they arrived on the scene. Sound sage advice below from uncle Rubl. Here is a link below which may prove helpful. www.pcadvisor.co.uk/test-centre/internet/3506734/best-cloud-storage-dropbox-google-drive-onedrive-icloud/ |

This is something to consider in Thailand: at the moment temperatures are much higher than 30C....approaching 40 in CM and I believe thay are even higher (or have been) in parts of Isaan. Would this reduce SSDs' reliability even further? A few notes. In general desktop and blade server like equipment have an 'operating temperature range' of 10 - 35/40 Celsius or 5 - 35 Celsius. That suggest that anything inside/attached should have similar operation temperature ranges, including SSDs. The article is talking about 'disconnected from power' SSDs. It may be that in that sense SSDs are more vulnerable than HDs (normal hard drives). I would expect that the higher the temperature the more vulnerable the SSDs become in 'disconnected from power' mode. For hard drives this article is probably still valid www.ehow.com/info_12300639_safe-temperature-store-hard-drive.html |

Agreed, I had a wander to Valhalla a while back, and can confirm there are no computers there. That's an urban myth, even though Valhalla itself is a real legend.
My advice would be very careful. Don't sit on clouds unless you really know what you're doing. They may look like soft springy cotton wool, but don't be fooled it's very easy to fall thru unless you know what you're doing.
For us wizards, we each have our strengths and weaknesses, and IT is not my specialism. For animals I would ask Radagast. When it comes to IT wizards I would seek the counsel of young Rubl here.

Of course there are no computers in Valhalla. All that thunder and lighting would make the computers very Thore. |

They have been tested in extreme heat of fires and still retain their data. |

except when the card warps like a taco in "extreme heat of fires".
