Back up the encryption_requests table and strongkeylite database from each cluster node before updates to ensure easy recovery if performance issues arise.

NOTE: This step requires stopping application server (Payara) on the appliance, so make sure the appliance is not receiving web-service requests while taking a backup.

1. Login into the appliance as strongauth user.
2. Stop Payara

   shell> sudo systemctl stop payara
   Ensure that Payara has been stopped using the following command:
   shell> nfn 8181
   
   If Payara still running, list the process ID and force kill the process:
   shell> pf payara
   
   shell> kill -9 (pid from the above command)
   

3. Take a backup of encryption_requests table.

   shell> mysqldump -u skles -p strongkeylite encryption_requests > /usr/local/strongauth/dbdumps/encreq-$(hostname)-$(date +%Y-%m-%d).db

4. Take a backup of whole strongkeylite DB.

   shell>mysqldump -u skles -p`dbpass 2> /dev/null` --no-create-info --ignore-table strongkeylite.decryption_requests --ignore-table strongkeylite.deletion_requests --ignore-table strongkeylite.search_requests --ignore-table strongkeylite.replication strongkeylite > /usr/local/strongauth/dbdumps/strongkeylite-$(hostname)-$(date +%Y-%m-%d).db
