It's real good, easy, fairly fast.
There's a feature that lets you establish an area that Windows can't see, so that any corruption of your operating system won't affect your backup there: Acronis Secure Zone.
Not free.
I have Acronis True Image Workstation 9.1 with Acronis Universal Restore. There are some other Acronis versions & products I'm not experienced with.
You get a stripped down but useful version of Acronis in MaxBlast 5 if any of your hard drives are Maxtor,
free at the Seagate web site
here.
Acronis may (or not, I don't know) also come free in SEagate DiscWizard at the same site as MAxBlast 5.
So try that if you are able.
