Consistency Group Snapshot

{{ $t('productDocDetail.updateTime') }}: 2026-01-05

Description

Add Oracle RAC virtual machines or multiple virtual machines of a business to the consistency group to implement consistent snapshots of the whole group of virtual machines. Ensure multiple virtual machines' snapshot data are generated simultaneously, and the business is available after snapshot recovery.

Precautions

  1. The snapshot taken before the virtual machine is added to the consistency group is not allowed to be rolled back, but the virtual machine can be cloned using the snapshot.

  1. Consistency group snapshots are only for virtual disks and shared disks on virtual storage. Disks that are not in virtual storage will not generate snapshot data.
  2. The consistency group snapshot limits the number of disks. The total number of virtual machine disks in the consistency group cannot exceed 64.

Prerequisites

Required virtual storage with 3 nodes and above.

Steps

  1. Click Reliability > Snapshots to enter the consistency group snapshot.

  1. Add a consistency group, select the associated virtual machines, and add them to the consistency group. After the virtual machine is added to the consistency group, the consistency group can be cloned to ensure the data consistency of the virtual machine after cloning.

  1. Delete Consistency Group: Delete the selected consistency group. Required to enter the admin password to proceed.
  2. Clone Group: Clone the VM inside the consistency group and create a new consistency group with the cloned VM.
  3. Take Snapshots: Take snapshots for the selected consistency group.
  4. Recover: Recover snapshot for the selected consistency group.
  5. Clone From Snapshot: Clone VM from the selected snapshot.
