I am using Acronis True Image 11 on Windows Vista x64 SP1. I have created a task to incrementally backup a non-boot drive every morning. Every time the backup runs, I receive the following two errors, that I must manually ignore to complete the backup. http://www.yorkrules.com/wp-content/uploads/Acronis/Acronis-Error.jpg http://www.yorkrules.com/wp-content/uploads/Acronis/Acronis-Error-2.jpg My Internet research suggested these errors may be virus-related. I turned off System Restore for the drive, restarted in safe mode, and used Avast Anti-Virus to scan all drives, which found nothing wrong. If you can suggest possible fixes, I'd appreciate it. Thank you.
