I looked for previous forum work for similar issues. The ones that were successful generally had enough stack trace to see a particular storage provider, and a means to fix. The stacks here don’t go far enough. Setting up a [–log-file](https://duplicati.readthedocs.io/en/latest/06-advanced-options/#log-file) could catch more, or if emailing errors, then perhaps raise this option above default:

```
C:\ProgramData\Duplicati\duplicati-2.0.4.5_beta_2018-11-28>Duplicati.CommandLine.exe help send-mail-max-log-lines
  --send-mail-max-log-lines (Integer): Limits log lines
    Use this option to set the maximum number of log lines to include in the
    report. Zero or negative values means unlimited.
    * default value: 100

C:\ProgramData\Duplicati\duplicati-2.0.4.5_beta_2018-11-28>

```
