Overview

To ensure data security and meet diverse business demands, Tencent Cloud Distributed Cache provides flexible automatic and manual full backup mechanisms:
Timed Auto Backup: The background system performs a full data backup once daily during the maintenance window 02:00 - 08:00. The backup data generates a standard RDB format file and is securely and persistently stored in Tencent Cloud Object Storage (COS).
On-Demand Manual Backup: In addition to scheduled system backups, you can also initiate full backups on demand through the console. Simply initiate a full backup at any time outside the automatic backup window to accommodate scenarios such as major version releases or as a data safeguard before critical operations.
Note:
During data backup, in order not to increase the processing burden on the master database or affect the business, the backup source will be a replica database in the instance.
