Lost data directory additional files

Hello there,
I have a little problem, i saved all my data from the cloud on my PC and deleted the partition on the server so i lost all the data like planned (because i want to save the data with rsync now before it was saved with a software raid) but i have the problem that all the Files and Folders that came additional to the installation of nextcloud in the data folder are gone, so i have only my data and an empty folder x) maybe anyone knows how to recreate or reinstall this data folder? Or do i have to reinstall nextcloud completely?
thanks for help and greetings from germany

Nextcloud contains Nextcloud folder itself and data folder that could be easily moved out. So what kind of

do you means?

This is short data folder example:

# ls -la data/
