Restore a copy of the encrypted database I have encrypted the backup using the method followed by the file server. Unfortunately, I did not keep a copy of the certificate of the process of encryption and unfortunately also the server was completely destroyed and is impossible to run again and I have to restore a copy of the database.
I have a copy of the rule but it is encrypted. Is there a solution to this problem?

Not sure what that means.

That's going to be impossible. If you don't have the encryption cert, you can't restore.

Rule? Not sure what a rule has to do with this.

Tell the people that you can't restore the database and it is lost forever.
