Deleting backup error


#1

I have duplicati running in a freenas jail with S3 storage (also hosted by freenas). I have tried to delete a backup and I receive this message when deleting the local DB and files,

The type initializer for ‘Duplicati.Server.WebServer.CaptchaUtil’ threw an exception.

Is there a missing pkg on freeNAS?


#2

Hi @umproko5, welcome to the forum!

I don’t run FreeNAS, but that message also appears in Deleting backup task issue with a fix that worked there.

If that helps you, I wonder if there’s a way to make sure that the package gets brought in without human help?


#3

I updated to the latest version of ubuntu and the capcha shows up but the backup is not deleted.

Is this a job that used to be running, but you decided to delete it along with remote files? On Windows, I get:

when I delete a job, also deleting the remote files, watching in About --> Show log --> Live, Information level.
When you say that the backup is not deleted, one guess is you meant the destination folder wasn’t emptied.
Are you talking about the .sqlite database that has job information? Please clarify and post a log like above.

Here is an example of delete a backup that isn’t working,

Are you using the default Mono from your distribution? https://www.mono-project.com generally does better.

https://forum.duplicati.com/search?q=Mono.Security.Protocol.Tls.TlsException can show some ways to a fix.

SSL TLS support in Mono might also apply but seems more complex. I’d suggest trying the latest Mono first.

With this sort of connectivity problem, does anything else work, or is a backup deletion all that you’ve tried?

Using “Test connection” on the destination screen of the job is often a simple way to see if you can connect.
