Replication support is enabled using the Configure dialog box. For information on accessing this dialog box, see Configuring the plug-in.
• |
Enable MySQL Replication: If native MySQL Replication is enabled for this instance, select this check box. |
• |
Slave Instance: If the instance is configured as a Slave, select this option. |
• |
Master Instance: If the instance is configured as a Master, select this option. |
• |
Enable Point-In-Time Recovery: If you want to enable PIT backups and restores, select this check box. |
• |
Binary Log Index Path: If you selected the Enable Point in Time Recovery check box, use this field to specify the complete path to the Binary Log Index file. |
• |
Relay Log Index Path: If you are configuring a Slave Instance, enter the complete path to the Relay Log Index file to include it in backups. |
Support for backing up native MySQL Replication environments has the following limitations:
• |
Slave replication servers: Backup types supported include: |
• |
• |
Masters replication servers: Backup types supported include: |
Incremental and Differential Backups on the slave server require that you enable the “--log-slave-updates” option in MySQL. This option tells the slave to log the updates performed by its SQL thread to its own Binary Log. For this option to work, the slave must also be started with the “--log-bin” option to enable Binary Logging. Normally, this option is used to chain replication servers; however, it can also be used for Binary Log backups enabling PIT Recovery of a replicated environment without the complications of purging Binary Logs on the master server before they have been applied to the slaves.
Using the Relay Log Index Path option, you can specify the full path name to the Relay Log Index file to include it in backups. By default, the status files, “master.info” and “relay-log.info,” reside in the same location. If you use the Relay Log Index Path option and the default filenames and locations are retained, the plug-in automatically backs up and restores all these files for a slave replication server.
