Further to my previous report, I went ahead and tried the S3 backup again, this time I got:
"Errors": [
"2025-03-28 08:54:26 +01 - [Error-Duplicati.Library.Main.Controller-FailedOperation]: The operation Backup has failed with error: Detected 306 file(s) in FilesetEntry without corresponding FileLookup entry in the following filesets:\r\nFileset 2: 10/03/2025 05:20:13 (id = 11)\r\nDatabaseInconsistencyException: Detected 306 file(s) in FilesetEntry without corresponding FileLookup entry in the following filesets:\r\nFileset 2: 10/03/2025 05:20:13 (id = 11)"
So I ran a repair and got:
"Messages": [

],
I then re-ran the S3 backup which then worked fine. A repair afterwards then showed:
"Warnings": [
"2025-03-28 11:08:28 +01 - [Warning-Duplicati.Library.Main.Operation.RepairHandler-LargeEmptyIndexFile]: The empty index file Duplicati.Library.Main.Database.LocalRepairDatabase+RemoteVolume is larger than expected, choosing not to delete it",

],
For the local backup job, it ran fine, but for curiosity I ran a repair on it and it logged:
"Warnings": [
"2025-03-28 08:58:19 +01 - [Warning-Duplicati.Library.Main.Operation.RepairHandler-LargeEmptyIndexFile]: The empty index file Duplicati.Library.Main.Database.LocalRepairDatabase+RemoteVolume is larger than expected, choosing not to delete it"
],
I’m still not sure what I’m supposed to do about these index files which it chooses not to delete.
