File-versioning

Nextcloud version 13.0.5
Operating system Ubuntu 16.04
Apache or nginx version (eg, Apache 2.4.25):
PHP version 7.0.30

Just a question for confirmation.

I want to activate versioning so no files are deleted.
I should put in the config:

‘versions_retention_obligation’ => ‘disabled’,

disabled
Disable Versions; no files will be deleted.

This sounds a bit confusing, is it right that this will cause that NO files are deleted definitely?

Regards,
Jan
