Hi Kern, Thanks for these tips... I didn't see them until just now... I actually fixed the database already based on documented changes that I had stored in my Wiki and bacula emails (containing JobId and VolumeName)... I verified the changes by doing a few restores and the aforementioned double migration jobs (that seemed to be the ultimate test)... I learned my lesson... Your support has been above and beyond the call of duty... You (and the entire bacula community) are great... 8-) Btw, I have turned on Binary Logging in MySQL so that I can replay the logs in the future. Thx, Mike
