Mariabackup for taking backup of mariadb databases

Today i have taken backup using mariabackup, with this utility you can take online full and incremental backups.

Below are the steps to be followed:

1. Create user as for backup:

MariaDB [(none)] > Create user 'mariabackup'@'localhost' identified by 'password';

MariaDB [(none)] > Grant reload,process,lock tables, replication client on *.* to 'mariabackup'@'localhost';

2. Install Maria backup:

#yum install MariaDB-backup

you will observe packages being installed and at the end will get message Complete !

3. Create a directory for backups, in my case i created /backup

4. take backups :

   #mariabackup --backup --target-dir=/backup --user=mariabackup --password=password

Backup will start and at the end you will get a message completed OK !

now we can go to the directory and check files created, you will see multiple files along with DB files that have backup related info -

backup-my.cnf,  xtrabackup_info, xtrabackup_checkpoints
