Online full backup of MySQL server 5.7 using the MySQL Enterprise Backup

We are going to make an Online full backup of my MySQL server 5.7 using the MySQL Enterprise Backup tool on Oracle Linux 7.

1. Table of Contents:

  • What is MySQL Enterprise Backup.
  • Enable The Bin Log
  • Make a full backup

2.What is MySQL Enterprise Backup.

a. MySQL Enterprise Backup delivers:

  • “Hot” Online Backups – Backups take place entirely online, without interrupting MySQL transactions
  • Incremental Backup – Backup only data that has changed since the last backup
  • Fast Recovery – Get servers back online and create replicated servers
  • Point-in-Time Recovery (PITR) – Recover to a specific transaction
  • and More.

b. Install MySQL Enterprise Backup:

# rpm -Uvh meb-4.1.0-el7.x86_64.rpm 

2. Enable The Bin Log:

MySQL Entreprise Backup use the binary log files
a. Edit the mysql configuration file: /etc/my.cnf

log-bin=/var/lib/mysql/mysql-bin
server-id=1

b. Restart MySQL server:

# systemctl restart mysqld

3. Make a full backup:

a. Create a destination backup:

# mkdir /backup-mysql/09-05-2019

b. Make an Online full backup:

# /opt/mysql/meb-4.1/bin/mysqlbackup -uroot -pORANUX --socket=/var/lib/mysql/mysql.sock --datadir=/var/lib/mysql --backup_dir=/backup-mysql/09-05-2019 backup-and-apply-log
