Duplicati Windows server 2012R2. Backup Fails, no useful info in Logs

I have several clients whom I am using Duplicati to backup to B2 Accounts.
On 1 I am having the following issue:
Backing up C:\Users, D:
Excluding system, hidden, and temp files.
No matter what logging level I set, I only get:
AES encyrption {random-file-name.zip}{hash}
in the logs.
The backups start. Then aborts with an “Error”. But when I click to show the error, there’s nothing there.
It succeeds in backing up around 3,000 to 5,000 files before crapping out.

I am new to Duplicati. I think the interface needs work. Dropdowns are not the ideal way to have to find stuff. Break the stuff in the drop downs into categories and give me tabs. I can’t tell if I am missing something to get more information into the log files so I can trouble shoot what is happening. I have been struggling with this particular one since May, and while there’s a ton of info out there, nothing seems to match my issue. Using 2.5.1 Beta.
(Which appears to be working fine on others, but don’t know for sure as I just found out today that I can setup email notices…)

Hello and welcome to the forum!

Try this … open two tabs to the Duplicati web UI. On the first tab go to About -> Show Log -> Live -> and in the dropdown select Warning. Switch to the second tab and click “Run now” for your backup job. Then go back to the first tab with the Live Log view and watch for warnings/errors. Copy/past here and we’ll try to help!

Here’s the log:

Ok, after reading the log for the umpteenth time (and after getting some sleep.) It appears I am hitting a daily cap limit. Is there a way to have duplicati pause the backup on this instead of crashing? I mean, it’s a hard limit, (I may be able to convince my boss to temporarily allow me to remove it…but it’s a daily xfer cap, not a storage cap.

Then I’m disappointed in the error they sent. This is very misleading if it’s a transfer cap being exceeded:

Message”:“403 - storage_cap_exceeded: Cannot upload files, storage cap exceeded. See the Caps & Alerts page to increase your cap.

If that message were right, you could set –quota-size to get a warning and error, but backup won’t pause.
I don’t think Duplicati does anything with transfer amounts besides log it (see Backend Statistics in a Complete log for your job, e.g. BytesUploaded). Backblaze can alert you by email or phone if it helps…

Duplicati shouldn’t be crashing this way though. That’s probably a bug, but default log doesn’t give a good view. If you watched About --> Show log --> Live --> Retry or set up log-file at log-file-log-level=retry, you’d possibly see it try 6 times (one intial try then default 5 number-of-retries with default 10 second retry-delay between tries). A very ugly way to pause would be to crank those values way high and wait for quota reset.

It was both. But the Backblaze side showed the transfer cap as the reason. The real issue: They removed the CC tied to the account, and hadn’t given a way to put it back, and no notification that payment method was missing until this morning. (After I opened a ticket with them, and no communication from them what so ever.) Suddenly this morning, the link to put in CC info reappeared. This is why I was ONLY having problems with one client. Now if they could just figure out how to do tabular reports so I can see more info on one screen. Currently it’s 1.5 clients per page, I don’t have many, but enough to have to scroll through about 30 pages of info. Oh, and the sort is random.

Next step, figuring out emailing reports from duplicati so I can keep up with the client side of whether backups are working or not.
