"Missing file" but they exist

[olyandros]

Hi,

I just ran a local backup to a HDD and Duplicati reports several files missing on the destination drive. I checkend and the reported files are present on the drive, don’t know why they are not found. I ran repair, but it failed. Need some help here.

Duplicati 2.2.0.1 - 2.2.0.1_stable_2025-11-09 on Win 10

Here are the logs:

Welcome to the forum @olyandros

@olyandros

I just ran a local backup to a HDD

Local? USB? One USB or rotation? Is Duplicati a Windows service or your user?

@olyandros

I ran repair

@olyandros

Here are the logs

Two oddities are that the repair log times predate the backup log times.
They also disagree heavily on missing files. Which files did you check?
Any pattern in them, e.g. are they from the same backup? You made 4.
Anything changed, different, or gone odd before the backup that failed?

Is log from the backup failure before repair at 13:12 around anywhere?
The backup log here is from 13:13. Study About → Logs → Stored too.
Sometimes clues land there in the server log, even if job log isn’t made.

[olyandros]

Thanks for the reply. Duplicati does not run as a service and I start the backup manually from the GUI.
It backs up an internal SSD to an external USB-HDD.

I think I copied the logs out of order as I tried to run the job several times and it always failed.
Here are some fresh logs:

The log says it is missing 61 files but lists only 20. All these 20 files exist on the target drive but are only 3-8KB in size.

@olyandros

lists only 20

There’s a limit of 20 on each category of messages in the short default job log.
Adding advanced option log-file=<path> should be able to log all warnings.
I’m a bit curious if the 10 dindex file warnings from Repair are also in backup.

@olyandros

are only 3-8KB in size.

I think you’re only looking at the dindex files. These are small (just an index).
Looking closely, the list changed. Comparing Dec 5 and Dec 7 lists finds that

duplicati-iea5442bf669e4a57aa1d90aff89f04d9.dindex.zip.aes
was replaced by
duplicati-ib572557b3f39481b917cfbf816ce0c34.dindex.zip.aes

There is a dindex recreate mechanism. Could you post the date for those two?
Possibly replacements are being uploaded – but I don’t see that in posted logs.

Another possibility is that file list wasn’t working, though I can’t imagine why.
There seems to be a consistent logs statement of “KnownFileCount”: 16241,
which I suppose you could sanity-check against Control-A selection in Explorer.

For a more detailed file-name based check, Job → Log → Destination → list
should let you see what Duplicati saw. Copy to clipboard can help to search.

I now tried and ran the purge-broken-files command and it seams to have solved the problem, backup now runs fine. But thanks for your support anyways
