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

By | | , ,

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
