I suddenly start to get the message while performing backup, I know i have taken backup of the certificate and stored it in my password manager which I still have access to. My question is that do we need to have backup cycle of certificate(s) backup? is there any default limit set from Microsoft that we need to take backup every x days. I know ,I took backup of certificate on '2017-02-03 15:57:53.000' i.e. 164 days ago.
Warning: The certificate used for encrypting the database encryption key has not been backed up. You should immediately back up the certificate and the private key associated with the certificate. If the certificate ever becomes unavailable or if you must restore or attach the database on another server, you must have backups of both the certificate and the private key or you will not be able to open the database.
