I have had every version of Acronis issued over the last 7 or 8 years and never had a problem.
As far as the latest version, 2012, is concerned I haven't suffered any of the problems identified in your post.
The only thing that I have noticed, and now accept, is that when it has started running the 'time left' starts at days then hours and eventually it takes about 30 minutes!
I only ever do full back ups and keep the last four on an external disk replacing them about monthly unless I have made significant changes in the interim.
I will probably regret this BUT I have never had a problem restoring an image. In fact I use Acronis rather the System restore.
