With the latest 2.8 canary build

I manually run again and it works

Interesting. I just started seeing this problem on the CI server:
https://travis-ci.org/duplicati/duplicati/jobs/277904947

I’ve also started getting this in last few days. Running latest canary. Sometimes it works sometimes it doesn’t.

Same here - got it for the first time on Friday when running a very small update job to B2, got it again just now when pushing a small update to GDrive.

6

Looks like this error occurrs if it fails to delete the oldest version of backup.

7

So the error doesn’t occur if the backup doesn’t use the --keep-time (Keep this number of backups) parameter?

8

Not to nag, but is there any progress on this issue? It now appears to be actively preventing my B2 backups from completing (though I could be seeing something wrong).

@saviodsouza, as an aside, can you edit this post and add it to the “Support” category? It’s currently marked as ‘uncategorized’ and that makes it one step harder to find.

Yes,

Because I am getting errors only in backup sets where keep max versions = xx is set.

I have other backup sets set to max 3m or 1y I do not get errors there.

Thanks for the confirmation!

Yep, I found and fixed the issue:

Just got a chance to try the 10-1 canary build, this issue now appears to be fixed.
