The whole point of backup software is that it backs up your software and works when you need it, every time you need it. Acronis claim all these wonderful things on their product page and I want a backup prog that will write to DVD. Tried it. It's crap, unreliable, relies on other peoples software which is known to be unreliable. When writing to DVD it flashes up a big warning window screaming unable to write to DVD maybee bad media etc etc. When all it should be saying is "Please insert the next disk" but even when it has completed all the disks, it cant read from them. You sit there like a trained monkey swapping disks in the drive as it asks for one then the other, just to be told after half an hor of this, that the backup is crap. Well I thought Acronis were supposed to be proffessionals, don't they even test their software? Tell you what guys. I WILL NOT BUY IT.
