Duplicati appears to backup but no data actually makes it to the endpoint.
Setup:
- NGINX Reverse Proxy (SSL’d) - 10.0.0.10
- Minio S3 - 10.0.0.11
- Duplicati client (macbook) - remote
I am able to upload files to the relevant bucket through Minio’s web interface. Duplicati acts like it is moving data onto the S3 server - the gigabytes to go consistently gets lower. Once it gets all the way down, it hangs on verification - likely because there is no data to verify!
NGINX Config (with Let’s Encrypt stuff and URLs redacted):
server {
server_name url.url;
location / {
proxy_set_header Host $http_host;
proxy_pass http://10.0.0.11:9000/;
}
proxy_buffering off;
client_max_body_size 0;
My guess is that the backups are happening but to a different folder than expected.
A few ways to check this include:
- If you monitor your bandwidth while a backup is running do you see any traffic?
- If you get a job summary email (or even in the “Results” block in the job Log menu item) do you see any values for things like “AddedFiles” or “ModifiedFiles”?
DeletedFiles: 57
DeletedFolders: 1
ModifiedFiles: 181
ExaminedFiles: 3791
OpenedFiles: 487
AddedFiles: 306
...
It looks like Duplicati acts like it is sending data, but it looks like no data is sent.
Edit: I verified NGINX is not at issue. I VPN’d in and used the local 10.0.0.11:9000. Problem still exists. No data shows in Activity Monitor and Duplicati behaves the same.
edit2: Duplicati acts likes its backing up even before the wifi has connected!
edit3: I never installed Mono. I bet that’s the issue. I didn’t realize it has to be installed separately.
edit4: Installed Mono. Identical error now. Rebooted Mac to make sure. “mono-sgen-64” has sent around 1MB, but Duplicati has “sent” well over a gigabyte. Minio web interface still shows the bucket as empty.
edit5: Confirmed working with Cloudberry. Nevertheless I want to use Duplicati if at all possible. I want free software to encourage friends and family to backup. If they have to pay anything, they won’t 
Wow I’m really confused - @Pectojin would know better, but I’m pretty sure you wouldn’t have gotten even the GUI interface to come on MacOS up if you didn’t already mono installed…
Have you tried a test restore yet? If nothing is being backed up, then a restore should fail.
Also, can you share your job configuration? Try the job “Export” menu and select “As Commandline…” then copy / paste that here (with person stuff like passwords and email addresses removed.
Well, I assumed I didn’t have Mono installed because it isn’t in my Applications folder. But it still isn’t, so it must install somewhere else. I probably already had it installed. I’ll get what you asked for soon. Thank you for your help. It means a lot.
