**Are you using external storage, if yes which one:** local/smb/sftp/...

**Are you using encryption:** yes/no
no
**Are you using an external user-backend, if yes which one:** LDAP/ActiveDirectory/Webdav/...

#### LDAP configuration (delete this part if not used)
<details>
<summary>LDAP config</summary>

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your Nextcloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM oc_appconfig WHERE appid = 'user_ldap';

Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Was the server-side encryption enabled at any time? Were files encrypted and/or keys generated?
You can check in <data>/<username>/ if there are encryption keys or encrypted files. If neither of them exists, there is just a files folder.
