Thank you for your reply. Yes, I think i didnt quite understand how the restore worked, but i figured it out eventually. One aspect of my question still remains, perhaps its missing documentation. The solr operator or a CRD allows one to do a backup. But a similar restore doesnt exist or is missing from the docs ? Thanks ! On Tue 10.
