Overview
After the database loses some or all of the data due to some reasons, the backup file can help you retrieve the lost data.
Prerequisites
You have configured the backup file download method in the current region.
You have completed an automatic or manual backup task. For directions, see Backing up Data.
Directions
1. Log in to the TencentDB for Redis console.
2. Enter the Backup List page by any of the following methods.
On the top of the instance list, select a region, and find the target instance in the instance list. Then, click the instance ID to enter the Instance Details page, and select the Backup and Restoration tab to enter the backup list.
On the left sidebar, select Database Backup to enter the backup list.
3. In the backup list, find the backup file to be downloaded, and click Download in the Operation column.
(Optional) If you select Database Backup in the left sidebar to enter the backup list, before downloading the backup file, click Details in the Operation column to view the backup details. After confirming the backup file information is correct, click OK.
4. In the Download Backup pop-up window, copy the download address or click Download to download the backup file. Cross-AZ download is not supported.
Public network download is disabled
a. In Download Conditions, the default values are the VPC ID and IP address configured in the current region, which can also be changed based on your needs.
b. If the instance is on a standard architecture, click Generate Download Address, and click Copy in the Download Address area.
If the instance is on a cluster architecture, click Generate Download Address. In the Download Address area, the download address of each backup will be displayed in a list, click Copy download URL to get the download address of backup data for each shard. Click Export Download Address to get the shell script that contains the download URLs of all backup shards.
Note
To change Download Conditions, you need to click Generate Download Address to regenerate Download Address.
The download address is valid for 6 hours. Get a new one after it expires.
Downloaded backup shard lists the shard node information of each shard, which is in the format of
instance ID-node-shard ID. The shard IDs are sequenced from 0.c. Download the backup file over the private nework.
Standard architecture: Run the command
wget -c 'private network address' -O backup.tar in a CVM instance to download the backup at a high speed over the private network. For detailed directions on how to log in to CVM, see Customizing Linux CVM Configurations.Cluster architecture: Run the .sh script on the CVM to download the backup file.
Public network download is enabled
a. Click Copy next to the Download Address.
b. Copy the download address and open it in a browser to download the backup file.
Yes
No
