Acronis True Image is a software that creates an image of the pc and takes a snapshot so when there is a system failure you can simply restore the pc to its original state.
Acronis 2009 and was a good piece software although on some computers it didnt work and it trashed the pc or you had restart all over again which meant data loss and reformat.
Acronis 2011 should have been an improvement from Acronis 2009 but the software just seems to be bloatware and installation is very slow and operating the software is confusing.
There are uncessary drop down menus where to store and locate files make the whole operating confusing and an annoyance.
stick to Acronis 2009 if you have and they dont provide any support. Support is a premium price and even then they dont provide support
