Acronis 10 just did its first new scheduled full back up to replace the existing full and differential ones. I would have expected to see only two files now in the backup location, the new full one plus the .cfg file. Instead, there are nine new files: One which appears from its size to be a full backup, plus seven more which, from their sizes, appear to be differential backups, and the .cfg file. These files are all dated today, starting with a time stamp of 0331. What happened, why did it happen; do I need to change anything in the scheduled backup instructions?
