Instructions on how to troubleshoot and resolve issues with corrupt backups
Introduction
This article describes how to set up Acronis True Image so that backups are saved to two or more external disks, which could be swapped or rotated on regular basis. For example, backup to disk A on even weeks and backup to disk B on odd weeks. The disk that is not used on a given week is usually kept in a different physical location as an extra layer of protection.
