Having an issue with Cloud sync tasks to Backblaze B2. This was working just fine until the last couple of days. I have checked that SSE is turned off and I have even created a fresh empty bucket on Backblaze to no avail. Can anyone give me some ideas as to where to begin beyond what I have already tried.
Thank you in advance.
Here is the error message I got:

Well, turns out my issue was I was trying to backup running LXC containers and VMs and just needed to turn on snapshot mode for those items. Thanks for all the help from no one!
Same error here on my end since upgrading to 25.10 and following. I don’t have snapshots enabled on my backups as I have nested datasets, which apparently won’t let me set snapshots to run. Here is the error.

I never had issues with backing up to Backblaze prior to upgrading from 25.04 to 25.10 and now 25.10.1. I actually removed the full backup to Backblaze and redid this once before uploading all the data into a brand new bucket and now it’s erroring out again. Here are more from logs:
