Modifying the Recycling Policy

Scenarios

DDS allows you to move unsubscribed yearly/monthly DB instances and deleted pay-per-use DB instances to the recycle bin.

Precautions

• The recycling policy is enabled by default and cannot be disabled. Instances in the recycle bin are retained for 7 days by default, and this will not incur any charges.
• Operations after an instance is deleted
  • If there are fewer than 100 backups (including automated full backups) in the recycle bin, the system retains the automated full backup from one day prior if available; otherwise, the latest one is retained. The system will also generate a new full backup. You can select one of the backups to rebuild the instance.
  • If there are 100 or more backups (including automated full backups) in the recycle bin, the system retains the automated full backup from one day prior if available; otherwise, the latest one is retained. You can select this backup to rebuild the instance.
• You can modify the retention period, and the changes only apply to the instances deleted after the changes, so exercise caution when performing this operation.
• Recycling and backup cannot be performed when a node is in the UNKNOWN state.
• If you delete an instance running out of storage, it will not be moved to the recycle bin.
