Backup stopped working (after Ubuntu restart?)

The last time Duplicati ran the daily backup according to the mails I get from duplicati-monitoring.com was Thursday October 3.
Now, when I login to http://localhost:8200/ngax/index.html and press “Run now”, I get the message “Starting Backup …” for one minute, then it switches back to "Next scheduled task: … ". (Backups usually take about 20 minutes.)

Running “ps -ef | grep -i Duplicati” in Terminal gives this:

henrik 1099 1 0 okt01 ? 00:00:02 DuplicatiServer /usr/lib/duplicati/Duplicati.Server.exe
henrik 1510 1099 1 okt01 ? 01:53:35 /usr/bin/mono-sgen /home/henrik/.config/Duplicati/updates/2.0.4.23/Duplicati.Server.exe
henrik 24399 19064 0 11:39 pts/0 00:00:00 grep --color=auto -i Duplicati

I can add that I use a B2 backblaze ‘bucket’ for the backups.

Any help would be very much appriciated.

I can add that I have this error message at the bottom of the screen:

“Error while running Lenovo-Ubuntu
Detected non-empty blocksets with no associated blocks!”

When I press ‘show’, I can see that the last message is from Oct. 3, when the last backup was created.

This is why backups aren’t running.

What version of Duplicati are you using?
Try clicking your backup set in the Web UI, click Database, then click Repair.

Good luck!

Hi drwtsn32
Thank you for your reply!
During a dialog here on another problem, I was warned that Repair could lead to very serious problems, so I chose Recreate. And that solved the problem! Thank you!
