Fatal error: Found inconsistency in the following files while validating database

Support

Additional troubleshooting done now, per this forum post tips from @Wim_Jansen:

  1. Made backup of my SQLite DB
  2. Located Dblock with ID 411493 using SELECT DISTINCT Remotevolume.Name FROM Remotevolume INNER JOIN Block ON (Block.VolumeID=Remotevolume.ID) INNER JOIN BlocksetEntry ON (Block.ID=BlocksetEntry.BlockID) WHERE BlocksetID=411493; (modified slightly from original post)
  3. Moved that ***.dblock.zip file out of remote folder
  4. Did a list-broken-files per this post

Result (note that this ran for almost 4 hours):
2025-07-11 12:00:12 -04 - [Information-Duplicati.Library.Main.Controller-StartingOperation]: The operation ListBrokenFiles has started
