Systemback - There has been critical changes in the file system during this operation (lxcfs)

Asked by Ken Krippeler on 2019-10-12

Hey,
I have an Ubuntu-Server for using Nextcloud and want to have restore points in case something goes wrong.
I tried using Systemback, but gave me an error message.

Here is the output of /tmp/systemback-cli_stderr:

I read on another thread that a similar issue has been fixed.
Sadly it doesn't work on my server.

Thank you for your work.

Thank you for your answer. I will try that later. :-)

Ken Krippeler (lichtverbunden) said : #3

Is it possible to exclude /mnt with the script? In the settings there is written that exclude only affects the home directory.

Best Kendek (nemh) said : #4

The contents of the /mnt directory are not included in the restore points, so it's not necessary to exclude.

Ken Krippeler (lichtverbunden) said : #5

Okay, thank you. I saw a few moments ago that it worked. Thank you a lot! :-)

Ken Krippeler (lichtverbunden) said : #6

Thanks Kendek, that solved my question.
