Question

How to manually back up or restore client MySQL/MariaDB database in Plesk for Windows?

Answer

1. Connect to Plesk server via RDP;

2. Open command prompt as Administrator
3. Back up client database:

   C:> "%plesk_dir%"MySQLbinmysqldump -uadmin -p -P3306 client_base > client_base.dump

   where:
   3306 - port for MySQL or MariaDB server;
   client_base  - database name; 
   client_base.dump  - name of database backup.

   Note: MySQL or MariaDB admin password will be asked during the commands execution. In case it is not known, it can be safely changed at Tools & Settings > Database Servers > localhost (default for MySQL or MariaDB) on port 3306.

4. Restore the database:

   C:> "%plesk_dir%"MySQLbinmysql -uadmin -p -P3306 client_base < client_base.dump

WARNING: just copying folder with database name from
'%plesk_dir%DatabasesMySQLdata' directory is not correct way of backing up.
