Performing MariaDB backups

Prerequisites

Before you perform the backups, you must meet the following prerequisites:

Ensure that versions of the MariaDB agent and NetBackup are same. If you upgrade NetBackup to newer version, then you must upgrade the agent version also.
(LVM users) Ensure that the MariaDB data directory and logs directory reside on the logical volume.
(Windows) Set the NetBackup\bin directory in the environment variable.
For example, Path =C:\Program Files\Veritas\Netbackup\bin
(Windows) Set the MariaDB\bin directory in user environment variable.
Configure the DataStore policy from the NetBackup Administration Console.
(LVM) Verify that there is enough space for the snapshot in the volume group, and then set the snapshot size in nbmariadb.conf file or by the command line.
Note:
Ensure that the snapshot size is 50% of the instance size that you want to backup.
(Linux) Create a symbolic link libmariadb.so and ensure that it points to the correct libmariadb.so.<n> library version.
Ensure that you update the MARIADB_LIB_INSTALL_PATH parameter in the nbmariadb.conf file with the absolute path of the symbolic link.
For more information, See Post-installation requirements for NetBackup for MariaDB Agent.
Set the FLUSH and LOCK user privileges.
Set the following parameters in the nbmariadb.conf file:
- DB_USER
- DB_PORT
- MASTER_SERVER_NAME
- POLICY_NAME
- SCHEDULE_NAME
- MARIADB_LIB_INSTALL_PATH
- (Linux) SNAPSHOT_SIZE
Verify the installing prerequisites and post-installation requirements.

To run the backup

Run the following command:
nbmariadb -o backup
-S master_server_name
-P policy_name
-s schedule_name
(Linux)-z snapshot_size
-l mariadb_library_path
[-portnum db_port]
[-u db_user]
(Optional) When prompted, type the database password. The NetBackup then connects to the database and initiates the backup.

Scheduling MariaDB backups from the NetBackup

You can schedule the MariaDB backups from the NetBackup Administration Console using the DataStore policy to call a backup script.
