Is that the entire D:\ missing from the backup?

Does the problem go away if you downgrade?

If problem is still reproducible, use About --> Show log --> Live --> Warning and click warning for details.

This is what was seen. Any patterns to what was seen and what was not seen (possibly Deleted* files)?

Export As Command-line will show the source paths in a form easy to cut-and-paste. Because 2.0.5.109 changed the code for source processing, any new issues may need path information (not the whole line).
Privacy redactions are of course fine, but please leave any punctuation or trailing spaces alone if you can.

Two messages every run:

I have not downgraded yet, but the backup works a few hours bevor upgrading. There was only a reboot in between.

Yes, entire D:\ is missing from backup.

Two backup path, >>“ExaminedFiles”: 165,<< - this is drive Z:

(edited slightly because I think there were actually two backslashes in original, before the forum ate one)

seem to be the bad combination, at least for my somewhat different error, tested on 109 (broke) and 108.
EDIT: To clarify, if I use subfolder on C:, it works. If I use --snapshot-policy=off, it works. Combo gets odd.

This one spat path names as expected, and I killed it because I didn’t really want to back up whole drive.

set AUTOUPDATER_Duplicati_SKIP_UPDATE=true

was done in advance to make Duplicati a single process, otherwise Control-C leaves the child running…

I’m not sure why my CLI message was less detailed, but after trying a test with two NTFS drives (like I assume you’re on) in the backup, and not seeing yours, I tried GUI C:\ with --snapshot-policy=required

I’ve updated Support problematic Windows paths #4256 with my idea of what “HResult”:-2147024773 is, likely ERROR_INVALID_NAME from the Win32 component. To see what was used may need debugger.

That PR sounds like a really good candidate for producing the problem!

I’ll investigate this with regard to Support problematic Windows paths #4256 later today.

Downgrading / reverting to a lower version should workaround this error.
Database’s version hasn’t changed since 2.0.5.106_canary_2020-05-11

I’ve submitted a pull request #4278 that fixes this, Fix snapshots broken by #4256. It undoes a change I made in #4256 that introduced this bug.

Thanks a lot, guys. All affected jobs are back on track (2.0.5.110). That was very quick help!
