Warning; no error - BackUp okay?

Got a warning, but “No Error”. Should I assume that the backup is okay?

2020-02-18 10:19:03 -05 - [Warning-Duplicati.Library.DynamicLoader.DynamicLoader`1-SoftError]: Failed to load process type Duplicati.Library.Common.IO.VssBackupComponents assembly /usr/lib/duplicati/Duplicati.Library.IO.dll, error message: Could not load type of field ‘Duplicati.Library.Common.IO.VssBackupComponents:_vssBackupComponents’ (1) due to: Could not load file or assembly ‘AlphaVSS.Common, Version=1.4.0.0, Culture=neutral, PublicKeyToken=959d3993561034e3’ or one of its dependencies.

I’ve been getting the same error as you have on my Mac. Reinstalled new version of Mono and reinstalled Duplicati - 2.0.5.1_beta_2020-01-18 and it seems to have fixed it.

Let me know if that fixes it for you.

Hmm, only happened once, the next couple of times everything seems to be ok - must have done a MONO update as you suggested.
