Backup

Available in Classic and VPC

In Backup, you can check the backup information configured per server for safe storage of cache data for users using Cloud DB for Redis. Also, when the cache data is damaged due to a failure, you can perform restoration using the backup file that was in storage. To use the backup and restoration, it is recommended to first understand the basic execution rules for the backup provided by Cloud DB for Redis. The basic backup execution rules are as follows:

• Backup execution methods
  • Performed daily, once a day
  • Select between automatic settings and user-defined settings
    • Automatic settings: a random time is selected, and backups are performed within 15 minutes from the selected time
    • User defined settings: backups are performed within 15 minutes from the time selected by the user
• Backup file
  • Retention period: can be stored up to 7 days according to the user settings
  • Storage location: a separate data storage is partitioned (storage contracts are made according to the backup file size)

The basics of using the backup are as follows:

Check backup settings list (VPC)

You can check the backup settings list per Redis server in operation. The following describes how to check the backup settings list.

1. From the NAVER Cloud Platform console's Platform menu, click and select VPC.

   • Redis service name: service name specified by user
   • Backup type: role of Redis server configured for backup
   • Shards: number of shards from the Redis server configured for backup
   • Backup retention period: maximum number of days for the backup file to be stored in the data storage partition (system backup only)
   • Backup start time: time at which the backup is performed once a day

   • Latest backup date: date for the latest backup that was performed
   • View details: details and restoration of the backup file list created per server

Check backup file list per server

The following describes how to check the backup file list created for each server after completing the backup:

Restoration

Cloud DB for Redis provides a service that enables you to restore lost cash data using backup files and create Redis servers quickly and easily. You can select the backup file you want to restore from the list of backup files in storage, and restore the Redis server. The following describes how to restore it.

1. From the NAVER Cloud Platform console's Platform menu, click and select between VPC and Classic.
2. Click Services > Database > Cloud DB for Redis, in order.
3. Click the Backup menu.
4. Click the [View details] button of the backup settings row you want to restore.
5. Click and select the file you want to restore from the backup file list, and click the Restore button.
   
6. When the Restore Redis page appears, check or enter the required information for restoration.
   
   • Memory per node: checks memory per node of the service to restore in case of the Redis Cluster
   • Number of shards: checks the number of shards for the service to restore in case of the Redis Cluster
   • Replicas per shard: checks the number of replicas per shard for the service to restore in case of the Redis Cluster
   • Backup time: checks the time that backup for the backup file to restore started, not in case of the Redis Cluster
   • Backup completion time: checks the time that backup for the backup file to restore completed, not in case of the Redis Cluster
   • Support high availability: select whether high availability for the server to restore is supported, not in case of the Redis Cluster
   • Server specifications: checks the specification of the server to restore, not in case of the Redis Cluster
   • Config Group: checks the config group information for the service to restore in case of VPC environment
   • Redis server name: enters the name of server to restore
   • Redis service name: enters the name of service to restore
7. Click the [OK] button.
8. Click the Redis server menu.
9. Check the status of the server being restored.
   • Creating: status in which the Redis is being created (restored) with the information entered by the user
   • Configuring: status in which the Redis server is being configured after being created (restored) with the information entered by the user
   • Running: status in which the creation (restoration) and configuration of the Redis server has been completed with the information entered by user, and access to Redis from the application servers is available

Store in Object Storage

In Cloud DB for Redis, you can store the created backup files in Object Storage and use them when performing backup. The following describes how to save a stored backup file to Object Storage:

1. From NAVER Cloud Platform console, click Services > Database > Cloud DB for Redis, in order.
2. Click the Backup menu.
