Does Synology ship with good tools? If so, I’d be curious in the answer, although with default 50 MB remote volume size, I’d think that uploads should be finishing up pretty fast, unless an upload got stuck. It’s too bad screenshot cut off an interesting part (Backend event), although one would really want to check all uploads.
Another possible method to see what’s moving or not:
Would it be possible to try a small test backup to see if it finishes? What’s odd here (to me) is that it seemingly was uploading, then it wasn’t, and right here is also kind of a special spot. Looking at the Backblaze web UI “should” show a series of new 50 MB dblock files, each with a smaller dindex file.
There will probably not be a dlist file near the end, as that looks like the point where upload stopped.
Looking at a few of my logs, when it announces the second “CommitUpdateRemoteVolume took”, a
couple more uploads still need to occur. If the Profiling log hasn’t moved, that doesn’t seem normal.
