How to disable backup security warning in Plesk?

Question

After logging in Plesk UI users receives this warning:

PLESK_ERROR: For security reasons, we recommend that you protect data contained in backups. Please go to Backup Settings and update backup security settings.

How to disable this warning?

Answer

This warning can be disabled only directly in database.

1. Connect to the server via SSH/RDP.

2. Log into database:

   # plesk db

3. By default backup_suggest_encrypt_backups parameter has list_only value:

   MYSQL_LIN: select * from misc where param='backup_suggest_encrypt_backups';
   +--------------------------------+-----------+
   | param | val |
   +--------------------------------+-----------+
   | backup_suggest_encrypt_backups | list_only |
   +--------------------------------+-----------+
   1 row in set (0.00 sec)

   In case output is empty, insert the needed value:

   MYSQL_LIN: INSERT INTO misc (param, val) VALUES ('backup_suggest_encrypt_backups', 'no');

   Otherwise, change this value to disable notification:

   MYSQL_LIN: update misc set val = 'no' where param='backup_suggest_encrypt_backups';
   Query OK, 1 row affected (0.11 sec)
   Rows matched: 1 Changed: 1 Warnings: 0

   Note: the above commands valid for both Windows and Linux servers.
