I have two computers running XP on a home network. For a couple of years, I've used Acronis 10 on each machine to backup their disks to an external drive. No problems until a couple of months ago. Then, Acronis on one machine started hanging up after selecting the drive to be copied, when asked to identify the target drive. About two weeks ago, the other machine started hanging at exactly the same point. Acronis 10 hasn't worked on either machine since. Acronis says they don't support version 10 anymore, and haven't tried to help. I suspect that a recent update to one of Microsoft's security programs is blocking the backup process. I bought a copy of NovaBackup for one of the machines, and it will start copying files, but it invariably stops before completing. Can anyone help me?
