#36 Barman.cli ERROR: Unhandled exception.


I am receiving this error message in our barman backup log file. It does not appear with any regularity but does appear multiply times. I thought it was related to backing up one of our larger servers, which are not completely successfully (I would guess a separate issue). We are using Barman: 1.3.0.

Here is the error message in question:

    I just figured out how to reproduce this error, just type: "barman status purecastdb01a"

      I was having the same error. It's dying on the line that should say something like: "Minimum redundancy requirements: satisfied (1/1)"

      If you simply run enough barman backup all's to meet your minimum redundancy requirements, barman status will start working correctly.

    Was a problem related to the output method. we have fixhed this problem and the fix is included in barman 1.3.1.
