ERUNT works just fine for me. I think the daily AutoBackup on startup default is 30 days. I changed mine to 7 days which is fine for me. I can say that the restore works great. Saved my PC more than once. If you want to change the default days, the info is in the FAQ.
Question: I want to change the number of days from which ERUNT AutoBackup keeps restore folders.
Answer: Click "Start" ? "Programs" ? "Startup", right-click "ERUNT AutoBackup", choose "Properties", then at the end of the command line add a space and the /days:n switch where n is the new number of days.
Very customizable for those who know command line and scheduling tasks.
