Force detailed log of all backup files and missing files

To me, path information underlies everything. Little point in debating, with more to discuss.

No. That’s what some software does. Duplicati looks at a variety of factors. Summary log info:

2024-12-31 12:51:00 -05 - [Verbose-Duplicati.Library.Main.Operation.Backup.FileEnumerationProcess-IncludingPath]: Including path as no filters matched: C:\PortableApps\Notepad++Portable\App\Notepad++64\backup\webpages.txt@2024-12-30_092527
2024-12-31 12:51:00 -05 - [Verbose-Duplicati.Library.Main.Operation.Backup.FilePreFilterProcess.FileEntry-CheckFileForChanges]: Checking file for changes C:\PortableApps\Notepad++Portable\App\Notepad++64\backup\webpages.txt@2024-12-30_092527, new: False, timestamp changed: True, size changed: True, metadatachanged: True, 12/31/2024 5:50:02 PM vs 12/31/2024 12:20:41 PM

I think the first line is saying that the file wasn’t filtered out of the enumeration, and the second explains why this file was being looked over to see if there’s something to backup as a change.

You can run a Verbose log to see if FileEnumerationProcess is seeing your new files, however

“ExaminedFiles”: 2930,
“OpenedFiles”: 2866,
“AddedFiles”: 2866,

says it’s not seeing much, but most of what it sees was not there on the previous look (so new).
Weren’t those Warnings from attempts to enumerate NetWare a problem on previous attempts?

If NetWare keeps not working, there may be no solution here, however to answer your question:

This is not natural use, but you can force it to try a full backup by deleting old destination and DB.
You can’t force it to succeed unless the source cooperates, and lots of other things can go wrong.
Starting fresh each time loses all the usual advantage of Duplicati versioning and change upload.

Technically, Duplicati does a full backup (or as full as Source allows) each time by default, but the deduplication makes it effectively an incremental backup in terms of the amount of data uploaded.

If you mean can one force NetWare to cooperate with full enumeration, that’s a NetWare question.

Have you considered using something else? Duplicati really needs the Source to cooperate with it.
