Create a Redis Cluster
This guide walks you through creating a new Redis Cluster on vDB, including cluster configuration, backup settings, and the option to restore from an existing backup.
Prerequisites
Your vDB account is activated.
At least 1 Backup Policy and 1 Backup Location (status Available, Product = vDB) are configured in Backup Center.
(Optional β if restoring from backup) At least 1 backup exists in Backup Center with a restore point in Completed status.
Step 1 β Go to Create Database
In the left menu, select Memory Store.
Click Create Database.
Step 2 β Basic Configuration
Fill in the general database information:
Engine: Select Redis.
Cluster Name: 3β63 characters, lowercase letters, numbers, and hyphens only.
Engine Version: Select the Redis version that suits your needs.
Instance Type: Select the CPU/RAM configuration.
Storage Size: Storage capacity in GB.
Step 3 β Cluster Configuration
In the Cluster configuration section, select your Cluster mode:
Single-node
Single master node with optional replicas. Suitable for smaller workloads and dev environments.
Cluster Mode
Replication across multiple nodes with automatic failover. Suitable for production and HA.
Select Cluster Mode to proceed with creating a Redis Cluster.
When Cluster Mode is enabled, the system supports High Availability with automatic failover. Note that some Redis commands are unavailable in this mode.
Configure Number of Nodes
After selecting Cluster Mode, configure the Number of nodes (2β10):
The total includes 1 Primary (Writer) and the remaining Replicas (Reader).
For example: selecting 4 nodes = 1 Primary + 3 Replicas.
The Cluster topology preview shows a visual diagram with the number of Masters, Replicas, and total nodes based on your configuration.
Step 4 β Restore from Backup (Optional)
If you want to create the cluster from an existing backup instead of an empty database, use the Backup Image section:
Backups from Backup Center are displayed directly as a table (includes both Auto and Manual Backups). Only backups with at least 1 restore point in Completed status are shown.
Find the backup you want, click the expand icon to view the list of restore points.
Select the radio button of the restore point you want to restore from.
When a restore point is selected, the system automatically pre-fills the instance settings (instance type, storage size, etc.) from the backup β you do not need to enter these manually.
The Storage Size of the new cluster must be greater than or equal to the Min.Restore Size (GB) of the selected restore point. Otherwise, the system will return an error and prevent cluster creation.
If no restore point is selected, the cluster will be created with an empty database.
Step 5 β Backup Settings
In the Backup Settings step, configure data protection for the cluster:
Backup Policy
Yes
Select a policy that defines the backup schedule and retention period from Backup Center.
Backup Location
Yes
Select a backup storage location (only locations with status Available and Product = vDB are shown).
Both fields are required β this step cannot be skipped when creating in Cluster Mode.
After the cluster is created, the Backup Location cannot be changed.
If no Backup Location is available, create one in Backup Center before proceeding.
Use the refresh icon next to each dropdown to reload the latest list from Backup Center.
Step 6 β Review and Create
Review all configuration on the Review page, then click Create Database.
The system will provision the cluster with:
1 Master node + the number of Replicas you configured.
Auto Backup running on the schedule of the configured Backup Policy.
Data from the selected restore point (if chosen in Step 4).
After successful creation, you will be redirected to the cluster detail page.
