Scenario
TencentDB for Redis® backend service regularly backs up instance data. By default, a full data backup is performed every day between 02:00 AM and 08:00 AM, generating an RDB format database backup file, which is persistently stored in Tencent Cloud COS service. In addition to the regular system backup, the TencentDB for Redis® console also supports manual backup, allowing full data backup at any time outside the automatic backup schedule, catering to various backup requirements for different scenarios.
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.
