Release: 2.1.0.116 (Canary) 2025-04-17

@jberry02

Is there any update on the issue with the b2 backend (and maybe others?) where upload errors are not getting detected? I am still seeing the “missing file(s)” error every few days with .116.

There was a bug with 2.1.0.4 stable, which prompted the release of a 2.1.0.5 release.
I am not aware of any issues with “missing files” for 2.1.0.116 or later.

@ts678

Does it also plausibly explain the second part, where Puts didn’t actually leave files (ouch)?

Yes (ouch indeed). The destination server is told in advance how large the file is. When the timeout happens it stops the transfer, and the destination server correctly discards the upload.

Since the failure is treated as a requested cancellation, no errors are triggered. During the post-backup verification step, this missing file is then seen as a partial upload and purged from the database, leaving no trace of the problem, besides an entry in the table RemoteOperation.

This post-backup cleanup was the reason that no testing found it. It simply purges the data associated with the missing file, making it as if some operations never happened. Only in the rare cases where it affects dlist files does it become immediately visible to the user.

It is hard to find in the database, but what you will see is that there is a PUT entry in RemoteOperation mentioning the file, but it is missing in Remotevolume.

Because files can be removed later, a missing entry in Remotevolume can be correct or a symptom of the error.

I have been building a more strict verification and cleanup strategy, so errors of this kind will be caught should they happen in other places.

I think this is the issue in question.

I thought it was a known issue that was being addressed, but if it isn’t I will certainly provide whatever info I can. I will post info the next time it happens.

I tested as well as @ts678.
I downloaded a few files from PortableApps (5 files, +700mb in total), and used that as the source. Destination is OneDrive (not the Business one), encrypted upload, disabled schedule, no other settings changed.

It worked as expected

Some secret sauce is missing I think. Could it be some network stuff?

I have become a rare case to study.
I don’t think there are any network problems, if i copy files to OneDrive manually i don’t encounter any problems.

@kenkendk

That sounds strange. A file with State = Temporary is safe to remove, so it should just be removed. Do you have a full error message (preferably with a stack trace)?

You can just remove it from the database if you want to recover, but I would like to know the sequence of events that causes it.

Stack trace? I don’t know where to find it, if you point me to the steps i will post it.

@jberry02

This is the bug that showed up several Canary releases ago. The recommended work-around was to set --read-write-timeout to 10 minutes. I have it set to 5 minutes, so if there is a significant difference going from 5 to 10 it could be why the work-around isn’t working for me.

That is the issue that was discovered for 2.1.0.4 and also some canary.

@jberry02

I think this is the issue in question.

I thought it was a known issue that was being addressed, but if it isn’t I will certainly provide whatever info I can. I will post info the next time it happens.

Yes, thanks for bringing it up. This issue would cause “(n) files missing from remote, please run repair”. I believe it is fixed in this canary.

There is a different issue related to timeout, which seems to cause deadlocks on some backends. The underlying cause of this is not yet discovered.

@Folgore101

I have become a rare case to study.
I don’t think there are any network problems, if i copy files to OneDrive manually i don’t encounter any problems.

And yet it happens consistently with Duplicati and consistently works fine directly?

@Folgore101

Detected 1 volume with missing filesets:

This is a different error message than the previous one? The previous one was about re-using a stream, this is about missing fileset for a remote volume.

I think this new message is related to issue 5862.

Was this an effect of the re-use error? It looks like a leftover temporary file is in the database, I just can’t figure out how to get it into that state.

It is in the UI under “About” then “Logs”.

Yes after a few tries that error appeared.
