I have some questions about the restore process of data with innobackup and xtrabackup.
The restart of mysql server is mandatory ?
This step is also mandatory ?
sudo mv /var/lib/mysql /var/lib/mysql-old$ sudo cp -R /var/backups/mysql/2011-03-19_19-08-58 /var/lib/mysql$ sudo chown -R mysql:mysql /var/lib/mysql
I must necesseraly destroy the datadir ? entirely ?
