Disable Virtual Drive

Nextcloud version (eg, 20.0.5): 16.0.3.0
Operating system and version (eg, Ubuntu 18.04): replace me
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.29
PHP version (eg, 7.5): replace me

The issue you are facing:

I wish to disable virtual drive so that I have a mirrored copy of my local files on the Nextcloud server. In this way I have a completely redundant copy and the safety that goes with it.

How to I accomplish this ?

Please upgrade your nextcloud version. Nextcloud 16 is not supported.

I think you only must install the nextcloud client software (windows, macos or linux) and configure it correctly.
