A manual backup is a full snapshot of a PolarDB for MySQL cluster that you create on demand. Use manual backups to capture cluster state at specific points based on your business needs.
Prerequisites
Before you begin, make sure that you have:
A PolarDB for MySQL cluster
Procedure
Log on to the PolarDB console.
In the upper-left corner, select the region where your cluster is deployed.
Find the cluster and click the cluster ID.
In the left-side navigation pane, choose Settings and Management > Backup and Restoration.
On the Data Backups tab, click Create Backup.
In the dialog box, click OK.
Limits
Each cluster supports a maximum of three manual backups.
Manual backup files can be deleted.
Modifying data after a snapshot is created increases the amount of snapshot backups, which increases the backup cost. Data modifications during defragmentation also increase the amount of snapshot backups.
Billing
If your database has 100 GB of data and you modify 10 GB after a snapshot is created:
You are charged for 100 GB of data storage and 10 GB of snapshot storage.
If you retain the snapshots when you delete your database, you are charged for 100 GB of snapshot storage.
