6.2. Backup Schedule

You can collectively query and manage information related to the backup of generated services.

The query and management items are as follows:

• Status

• Red: When the latest backup has failed 
• Green: When the backup is being performed normally 
• Yellow: When there is no recent backup 
• Gray: When no backup operation has been performed, but it is not a failure 
• Service Name
• Service Type
  • MariaDB
  • Redis
• Backup Disk
  • In use
  • Not in use
• Backup Settings
  • ON
  • OFF
• Retention Period 
• ICOS Usage (MB) 
• Full backup
  • Backup Cycle: The frequency at which a full backup is performed (daily or weekly on selected days)
  • Backup Time: The time at which the full backup is performed on the selected days (between 18:00 - 07:00)
  • Backup Size: The size of the stored full backup file
  • Elapsed Time: The time taken to complete the full backup
• Incremental Backup
  • Backup Cycle: The frequency at which incremental backups are performed (selectable intervals: 1, 2, 6, 12, or 24 hours)
  • Backup Size: The size of the currently stored incremental backups
  • Elapsed Time: The time taken to complete the incremental backup

The following items can be modified in the backup scheduling list:

• Backup Settings
• Retention Period
• Backup Time
• Backup Frequency

6.2.3.1. Changing Backup Settings

You can enable or disable scheduled backups.

• ON: Scheduled backups are enabled.
• OFF: Scheduled backups are disabled.

6.2.3.2. Changing Retention Period

You can modify the retention period of scheduled backup files.

6.3.DB Replication

This feature allows you to replicate a Target DB using a backup copy from a Source DB.

Only services with an existing MariaDB backup will be displayed, allowing you to configure the desired Source DB and Target DB.

• Source DB: The MariaDB service to be replicated (Backup required)

  • Namespace: The namespace of the MariaDB service
  • Service Name: The name of the MariaDB service
  • Backup Date: The backup file (by date) to be used for replication

• Target DB: The MariaDB service where the backup will be replicated

  • Namespace: The namespace of the Target DB
  • Service Name: The name of the Target DB

6.3.1. Performing Database Replication

6.3.1.1. Selecting Management

Access the Cloud Z DB Portal and click Management from the left menu.

6.3.1.2. Selecting Database Replication 

Under Management, click Database Replication to access the replication management screen.

6.3.1.3. Selecting Source DB 

Choose the Namespace, Service Name, and Backup Date of the database you want to replicate.

6.3.1.5.Performing Replication 

Click the Apply button to execute the replication.

6.4.Failover

Provides management for Auto-failover settings in MariaDB configured with Master/Slave replication.

Only redundant MariaDB services are displayed, allowing you to check the Auto-failover ON/OFF status, failover conditions, and failover timestamps.

For details on Auto-failover, refer to 8.7.2. Auto Failover.

6.5.Notifications 

Cloud Z DB allows you to set rules for receiving notifications based on various conditions.

Currently, notifications can be configured for Health, Usage, and Replication, with the following monitoring options:

• Pod: Alerts when a Pod stops running
• Container: Alerts when a Container stops running
• Database (DB): Alerts when the database stops running
• CPU: Alerts when CPU usage exceeds the threshold
• Memory: Alerts when memory usage exceeds the threshold
• Connections: Alerts when the number of connections exceeds the threshold
• Slow Query: Alerts when slow queries exceed the defined threshold (2-minute interval)
• Status: Alerts when a Slave fails to replicate from the Master
• Delay: Alerts when replication from Master to Slave is delayed

Each service can have different settings for activation, severity, and thresholds, allowing precise and customized notifications.
