we are backing up a server to do a restore, however, i want to make sure that the Mysql users are saved as well

anyone know where these users are actually kept? or are they kept in the /var/lib/mysql/user_db folder?

/var/lib/mysql/mysql

thanks

moved those over, but that didnt work, none of the users are registering after restore .....

They would need to be setup as on the previous server (or backup) in the associated directory in /var/lib/mysql/*dbname*

chown -R mysql.mysql /var/lib/mysql/*dbname*
