MySQL Enterprise Backup User's Guide (Version 4.0.3)
For most backup operations, the mysqlbackup
command connects to the MySQL server using the credentials
supplied with the --user and
--password options. The specified
user needs certain privileges. You
can either create a new user with a minimal set of privileges,
or use an administrative account such as root.
The minimum privileges for the MySQL user with which mysqlbackup connects to the server are:
RELOAD on all databases and tables.
CREATE, INSERT,
DROP, and UPDATE on
the tables mysql.backup_progress and
mysql.backup_history, and also
SELECT on
mysql.backup_history.
SUPER, to enable and disable logging, and
to optimize locking in order to minimize disruption to
database processing.
REPLICATION CLIENT, to retrieve the
binary log
position, which is stored with the backup.
PROCESS, to process DDL statements with
the ALGORITHM = INPLACE clause.
To create a MySQL user (mysqlbackup in this
example) and set the above-mentioned privileges for the user to
connect from localhost, issue statements like the following from
the mysql client program:
CREATE USER 'mysqlbackup'@'localhost' IDENTIFIED BY 'password';
GRANT RELOAD ON *.* TO 'mysqlbackup'@'localhost';
GRANT CREATE, INSERT, DROP, UPDATE ON mysql.backup_progress TO 'mysqlbackup'@'localhost';
GRANT CREATE, INSERT, SELECT, DROP, UPDATE ON mysql.backup_history TO 'mysqlbackup'@'localhost';
GRANT REPLICATION CLIENT ON *.* TO 'mysqlbackup'@'localhost';
GRANT SUPER ON *.* TO 'mysqlbackup'@'localhost';
GRANT PROCESS ON *.* TO 'mysqlbackup'@'localhost';
The following additional privileges are required for using specific features of MySQL Enterprise Backup:
For using transportable tablespaces (TTS) to back up and restore InnoDB tables:
LOCK TABLES and
SELECT for backing up tables.
CREATE for restoring tables.
DROP for dropping tables if the
restore fails for some reasons.
FILE for restoring tables in
external tablespaces outside of the server's data
directory.
For creating tape backups using the System Backup to Tape (SBT) API :
CREATE, INSERT,
DROP, and UPDATE
on the mysql.backup_sbt_history
table
Set those additional privileges if you are using the features
that require them. To set all of them, issue a statement like
the following from the mysql client program:
GRANT LOCK TABLES, SELECT, CREATE, DROP, FILE ON *.* TO 'mysqlbackup'@'localhost';
GRANT CREATE, INSERT, DROP, UPDATE ON mysql.backup_sbt_history TO 'mysqlbackup'@'localhost';
