I've got one full and several incremental builds on my laptop, 'safely' stored in the Acronis Secure Zone. I need to move these to an external drive to improve safety in case my internal hard drive fails at any future point. To do this, I tried mounting an image of one of these back up builds and then copying all the files across to the external drive. Acronis started to do this OK, but then returned a message saying words to the effect that it could not complete this action as the files were currently in use! This can't be possible as they are Acronis back ups I made months ago in the Secure Zone. Any ideas guys?
