What does this warning mean

I get the following warning from time to time. The next time I run the backup it does not occur. Can someone tell me what it means?

2020-09-17 09:08:45 -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=, Culture=neutral, PublicKeyToken=959d3993561034e3' or one of its dependencies.

Are you running Linux or MacOS? If so you can ignore this error as VSS components aren’t needed anyway. The warning message has been fixed in the Canary channel, so when the next Beta is released and you upgrade the message will no longer occur.

I am running Linux. Thank you for the information. I will ignore the warning for now.
