First off, sorry about the ALL CAPS subject. I just pasted in what I got from amanda.

On Monday the 17th my backups completed normally with the expected "RESULTS MISSING" messages from systems that were not present when the backups executed:

Hostname: fraud.davenjudy.org
Org : DailySet1
Config : DailySet1
Date : July 17, 2012

These dumps were to tape DailySet-24.
The next 2 tapes Amanda expects to use are: DailySet-25, DailySet-26.

Everything is missing but no errors are reported that I could follow up and fix. I looked in the amdump files and log files and everything looked normal except the report e-mail. I was busy with my day job so I only had time to do some minimal troubleshooting like running amcheck plus I removed the two "missing" disk definitions for bend (partitions on an external hard disk).

On Wednesday the 19th I got:

The rest of the backups for this week have run with no problems either.

Everything is back the way it's supposed to be. The "missing" disk definitions on bend had been missing for over a month so I doubt that they suddenly caused a problem. I hit Google with the subject of this post and didn't find anything helpful. Anyone have any idea 1) what went wrong and 2) how do I prevent it from happening again? It's nice when problems just go away on their own but that doesn't mean the problem is solved.

Cheers,
Dave
