The following items can be configured:
Configuration Item | Description |
Data backup | Backup Start Time: The time when the data backup task is enabled. The system enables the backup task within the time period you set. Backup Frequency: By Week: You can schedule data backups on a daily basis for Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday. By Month: This option supports configuring backups on a monthly basis. The interval between scheduled backup executions you select cannot exceed two days. Backup Retention Days: 7 - 1830 days. Backup sets are automatically deleted upon expiration. Scheduled Retention: Periodic backup builds upon regular automatic backup to provide a more flexible backup policy. This feature allows you to configure the number of backups to retain on a weekly, monthly, quarterly, or yearly basis. It does not require retaining additional new backup files. However, the retention period for periodic backups differs from (and is longer than) that for regular backups. After you disable periodic backup, no new periodic backups are generated, and existing backup sets are not deleted immediately. You can modify the retention period for periodic backups to clean up existing periodic backups. |
Log Backup | Log Backup: This feature provides two options: enable and disable. After you disable log backup, you cannot perform PITR recovery. Backup Retention Days: This can be set to a value between 7 - 3650 days. It must be greater than or equal to the data backup retention period. Log backups are automatically deleted upon expiration. |
Manual Backup
1. Log in to the TencentDB for PostgreSQL console, click the Instance ID, and go to the instance management page.
2. Click Manual Backup to initiate a manual backup operation.
Note:
Manual backups do not expire automatically. Clean them up periodically to prevent them from occupying storage space for an extended period.
Billing for Cloud Disk Backup
TencentDB for PostgreSQL instances that use cloud disks are allocated a certain amount of free backup space based on the instance. The size of the free backup space is 200% of the storage space of the primary instance you purchased.
The free backup space (per instance) = the total storage space of the purchased PostgreSQL primary instance * 200%.
The billable portion (per instance) = data backup volume (for that instance) + log backup volume (for that instance) - free backup space (for that instance).
Backup Pricing
Backup space exceeding the free quota is billed at USD 0.00003676/GB/hour in the Chinese mainland and at USD 0.00004118/GB/hour in other regions.
