Category | Backup and Recovery | Explanation and Description | Operations |
Data Backup | 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 Tencent Cloud Distributed Cache console. | |
| Manual Backup | In addition to automatic backup that is performed by the system backend regularly, you can manually back up your instance in the Tencent Cloud Distributed Cache console to meet your diversified needs. | |
| Backup File | The backup list will display all the backup files of the instance and backup information. Tencent Cloud Distributed Cache 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, Tencent Cloud Distributed Cache 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 | Instance Clone | Tencent Cloud Distributed CacheMemory 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. | |
