A month or so ago I created a scheduled task to each second day have TI make an Incremental BU of one of my disk partitions. The BU is defined to create Incrementals and to, after each 7th Incremental, restart the cycle with a new Full BU. It worked OK for 2,? cycles but one day, with no obvious reason, the log started showing an error msg like this "67 Error 9/02/2008 13:23:37 Enumerator is invalid. $module="C:\Program Files\Common Files\Acronis\Fomatik\Backup.dll"". Since that msg started occuring, TI continues to create new Incrementals (does not restart the cycle with a new Full BU). I have now already 1 full BU and 14 Incrementals, and counting. Can anyone tell me what this msg means and how I can resolve the issue?
