Backup

Available in VPC

In Backup, you can view the backup information configured per server for safe storage of cache data for users using Cloud DB for Cache. 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 Cache. 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
  • Manual Backup
    • Backup available for user to backup and delete
    • Only 1 backup every 30 minutes
• Backup file
  • Retention period: You can store for up to 7 days according to the user settings.
  • Storage location: Separate data storage is partitioned (storage contracts are made according to the backup file size)
