I’m running Duplicati 2.0.4.5_beta_2018-11-28 on Windows Server 2016 Standard. Not as service, just running in systray. Backing up to Minio on a Debian machine.
For a while now Duplicati quite often crashes during backup resulting in Duplicati disappearing from the systray so I need to start i again. I had a similar problem a year ago where one single file on the backup server was unreadable due to a disk error.
But this time I’ve run DuplicatiVerify.py and it doesn’t complain about any file being broken or wrong, it just complains about a ton of files missing which I really don’t understand at all?
Last time I had a similar problem I made a special version of DuplicatiVerify.py that doesn’t crash when a file is unreadable but instead reports "“Can’t read file chunk” which did not happen now at all but did last time when a file was unreadable.
DuplicatiVerify_hack.zip (1.2 KB)
The result of the check is here verify.zip (1.8 MB) which reports:
160 dlist “File missing”
14 dlist “Verifying file”
79054 dblock “File missing”
23296 dblock “Verifying file”
.
The mail(!!) I get when it crashes is this:

Not sure what I could do next to verify if any file is faulty. Is there any new way of checking, maybe this one is obsolete? And also still a bit odd that Duplicati crashes totally on whatever is wrong?
