Flush operation is not supported in Read Mode

I have a problem with the message as in the title. Other backups to the same storage work normally. I am sending logs.

[reply=“Radek;d9439”] It looks like you haven’t updated the software for a while. Can you try with the latest version?

Hello, yes I know. This is because new versions do not run on the server. Other configured backups from the server to the same destination work. why can’t this one? Is there any other way apart from changing the version?
