That seems to be the same issue as this one:

Do a verify to Ensure there is no data corruption. If no problems are found, your backup should be fine.

(I edited your post for better readability. Type ``` before and after pre-formatted text to make it more readable).

#3

Yes, It looks the same. One weirdness is that the filename is not a filelist:

Probably some variable that should have been reset, but was not.

#4

I experienced this error and Duplicati isn’t cleaning up after itself (leaving files in the temp directory, which eventually caused a disk full error and crashed Duplicati).

I’ll leave things in place for awhile in case anyone has any ideas, but as it’s going to fill temp again I’ll have to clean it up eventually.

#5

Quick update, I ran a verify with “Success” and re-ran the backup job with Success and no errors, but the old files remain in the temp dir. Since I use a ramdisk as a temp dir, I guess I’ll have to check it manually from time to time to make sure it doesn’t fill up. I wonder if there’s a way for Duplicati to alert when files are left over after a backup operation.

#7

I see a suspected mismatch of ID types in the code. syntbase uses GetRemoteVolumeFromID which takes a RemoteVolume table ID, but is given a Fileset table ID from lasttempfileid which uses GetIncompleteFilesets. This could explain the weirdness when it targets dindex and dblock files. The variable isn’t used in the actual synthetic filelist creation but might suppress it inadvertently, in addition to causing hard-to-answer questions.

Found this while looking at my own log warnings of this sort while wondering if there’s any reasonable way of digging the last few files out of the partially completed backup here where it’s unclear it will do more backups.

Failed first upload
Conflict when changed to smart retention and can't revert either!
Restore Backup with only dblock and dindex files
Initial backup should be able to be repaired
