Last backup was in the future - how to ignore the last backup?

The time test looks unavoidable (even if one looks in code before this):

duplicati/duplicati/blob/0306b3dd531c3644a4cb2524a22d76b715504b80/Duplicati/Library/Main/Operation/BackupHandler.cs#L451-L454


      
          // Grab the previous backup ID, if any

          var prevfileset = m_database.FilesetTimes.FirstOrDefault();

          if (prevfileset.Value.ToUniversalTime() > m_database.OperationTimestamp.ToUniversalTime())

              throw new Exception(string.Format("The previous backup has time {0}, but this backup has time {1}. Something is wrong with the clock.", prevfileset.Value.ToLocalTime(), m_database.OperationTimestamp.ToLocalTime()));

You might have to use the delete command to remove that version. Easiest way is by Commandline in GUI, adjusting things as necessary. Compared to backup, the main format difference is the lack of source paths. You’d also want to specify a –version (probably 0, but you can look at Restore from dropdown) or similar. Adding and checking –dry-run on a test run of delete will add confidence the 2019 version will be deleted.

Did it actually make one that you can restore from? I’d have thought the time issue would have blocked that, however if there’s really a 2018-2019-2018 sequence in Restore from, directions above need changing…
