Manage a Redis Cluster

After creating a Redis Cluster, you can manage its topology, change the number of replicas, trigger manual backups, and delete the cluster directly from the cluster detail page.

Prerequisites

  • At least 1 Redis Cluster in Available status exists.

  • Database management permissions on the vDB account.

Filter the Database List

The Database list page supports quick filtering by deployment type using tabs at the top of the page:

Tab
Shows

All Databases

All databases (Single-node and Cluster)

Single-node

Single-node databases only

Cluster

Cluster databases only

A count badge is shown next to each tab name. The quick filter works together with search: when on the Cluster tab, search results return only Cluster databases.

View Topology

The Topology tab on the cluster detail page displays the full master–replica structure of the cluster.

To view Topology:

  1. Go to the Redis Cluster detail page.

  2. Select the Topology tab.

This tab shows:

  • Master node: Green database icon labeled "Master".

  • Replica nodes: Icons displayed below, showing up to 2 replicas; the rest are grouped as "+N".

  • Summary: Number of Masters, Replicas, and total nodes.

Change Number of Replicas (Edit Nodes)

You can scale up or scale down the number of Replicas after cluster creation with no downtime.

To change the number of Replicas:

  1. On the cluster detail page, select the Topology tab.

  2. Click Edit nodes.

  3. In the Edit Cluster dialog, select a new Number of nodes — the UI shows only two options: current−1 or current+1.

  4. Review the Cost Summary panel on the right:

    • CURRENT CONFIGURATION: Current setup and price.

    • NEW CONFIGURATION: New setup and price.

    • Total: Cost difference (green = increase, red = decrease).

  5. Click SAVE to apply.

Each edit allows only ±1 node at a time. To reach a target node count, save and repeat the operation. This ensures each sync completes before the next step, preventing replication errors.

Manual Backup (Back up now)

The Back up now button is located directly in the cluster detail page header, allowing you to create a Full Snapshot immediately without navigating into submenus.

To create a Manual Backup:

  1. On the cluster detail page header, click Back up now.

  2. Confirm in the dialog: "This will create a full snapshot of [cluster name]".

  3. Click Back up now.

The system will show a "Manual backup is being created" notification and the new backup will appear in the Backup tab with In Progress status.

  • The Back up now button is disabled when a backup job is already running (Auto or Manual). A tooltip will display: "A backup job is currently in progress".

  • When the account quota is exceeded, the system returns a QuotaExceeded error and does not auto-retry.

  • Only Full Snapshot is supported — Incremental manual backup is not available.

View Backup Information

The Backup tab on the cluster detail page lets you monitor backup status and history.

To view Backup information:

  1. On the cluster detail page, select the Backup tab.

This tab shows:

  • Backup Information: Description, Created Date, Latest Record, Backup Size, Backup Policy, Backup Location.

  • Backup List: List of backup records with columns: Backup DB Point ID, Backup Size (GB), Backup Type, Schedule Type, Backup Location, Backup Point, Status, Action.

Click View full backup details → to open the detailed backup page for this cluster in Backup Center (opens in a new tab).

Manage Backups in Backup Center

The vDB Backup page (menu: Memory Store > Backup) shows a summary of your backups. For full management operations (Restore, Delete, Policy management), you need to go to Backup Center.

State
Action

No backups yet

Click Create a Backup to be redirected to Backup Center to create one.

Has backups

Click Go to vBackup to open Backup Center (filtered by Vault vDB).

Click a backup name

Opens the backup detail page in Backup Center (new tab).

Delete a Redis Cluster

Deleting a cluster cannot be undone. All data will be permanently deleted.

To delete a cluster:

  1. On the cluster detail page, click the More Actions (⋮) icon.

  2. Select Delete.

  3. In the confirmation dialog:

    • (Optional) Check Create final backup? to take a final snapshot before deletion (only available if the cluster still has a Backup Database in vBackup).

    • Check I acknowledge... to confirm you understand backup access will be lost.

    • Type delete in the confirmation input field.

  4. Click the red Delete button to complete.

If the cluster's Backup Database has already been removed from vBackup, the Create final backup? checkbox will be disabled and the system will display: "No backup database found. Final backup is unavailable."

Action Menu

From the Database list page, click the Action (⋮) icon next to a Redis Cluster for quick actions:
