Creating a Manual Backup

Prerequisites

You can create backups (including manual backups, automated backups, and incremental backups) only when the hidden nodes of cluster instances and replica set instances are normal.

Description

• Backup type

  Full backup: All data is backed up even if no data is updated since the last backup.

• Backup mode

  Physical backup: Data is copied from physical disks.

• Table 1 lists the manual backup methods supported by DDS.

  Table 1 Backup methods

  Instance Type	Backup Mode	Backup Type
  Cluster	Physical backup	Full backup
  Replica set	Physical backup	Full backup
  Single node NOTE: Single node instances apply to only a few scenarios. You are advised to use a single node instance only for learning.	Physical backup	Full backup

Pricing Details

• After you purchase an instance, DDS will provide additional backup storage of the same size as you purchased. For example, if you purchase 100 GB of instance storage space, you will obtain 100 GB of backup storage space. If the size of backup data does not exceed 100 GB, the backup data is stored on OBS free of charge. If the size of the backup data exceeds 100 GB, you will be charged based on the OBS billing rules.
• You can check your expenditure records for DDS backup fees by going to Billing Center > Bills.

Precautions

• The backup process does not affect services.

• When you delete a DB instance, its automated backups are also deleted but its manual backups are retained.

   • During the creation of a manual backup, you can query the backup status on the Backups or the Backups & Restorations page. The backup status is Backing up. The time it takes to complete the backup depends on the size of the job.
   • If the manual backup is successfully created, the backup status is Complete. The manual backup type is Manual and the backup method is Physical.
