Overview
Last updated: 2024-11-15 11:36:37
Overview
TencentDB for Redis® supports data backup and restoration. The backend service can automatically back up the instance data on a regular basis in the console. Manual backup can also be performed at any time. The backup data is saved in RDB format corresponding to the Redis Engine Edition and stored in COS for high data reliability. TencentDB for Redis® supports instance data restoration through clone.
Automatic Backup
By default, a full data backup will be performed every day between 02:00 AM and 08:00 AM. In order to avoid increasing the processing burden on the master database, the backup data comes from replica nodes. You can flexibly configure the start time period of automatic backup tasks based on your conditions. You can see the daily backup data in Backup and Restoration in the TencentDB for Redis® console. For more information, see Backing up Data.
Manual Backup
In addition to automatic backup that is performed by the system backend regularly, you can manually back up your instance in the TencentDB for Redis® console to meet your diversified needs. For more information, see Backing up Data。
Backup File
The backup list will display all the backup files of the instance and backup information. TencentDB for Redis provides two backup download addresses: private network and public network, and you can choose the one that best suits your needs.
Download from public network: You can download backup data anywhere you can access the Internet. The public network download is enabled by default, and you can disable it as needed.
Download from private network: In order to prevent database backup data from being dragged, TencentDB for Redis® allows you to download backup files from specified servers on the allowed private network. You can’t download backup files across regions, and you can do so only in the region where the Redis instance resides.
Data Restoration
Only TencentDB for Redis® 2.8 supports fast data restoration based on backup files.
Instance Clone
TencentDB for Redis® Memory Edition (excluding v2.8) supports instance clone, i.e., creating a complete instance based on a backup file. The data of the instance is the same as that in the backup file. You can use the clone feature to analyze previous data. You can also roll back an instance by swapping the IPs of the new instance and the original instance.
