Well recently I’ve had a couple of people complaining about their pc because windows or something has come up with a error and can’t get access to it.
And most of these times you will find that they will format the hard drive, without burning a CD of all their stuff, which really ticks me off because that means I have to help them getting everything back on their computer.
The answer is backups you can setup a simple backup machine on your LAN easily using things like FreeNAS allowing you to send your files to that machine from another on your LAN.
Or the simple idea is use Linux Live to get your files back, a simple disk like Knoppix or Damn Small Linux will allow you to get access to your partitions allowing you to recover your files without logging onto windows.
