Backing Up a FlexusX Instance

Scenarios

CBR can be used upon application and can enhance data integrity and service continuity. You can back up FlexusX instances manually or configure a policy to back them up automatically. This section describes how to back up a FlexusX instance manually.

Constraints

To ensure the integrity of backup data, do not delete disk data or restart or stop the FlexusX instance during the backup.

Prerequisites

The FlexusX instance is associated with a backup vault. For details, see Associating a FlexusX Instance with a Backup Vault.

Procedure

1. Log in to the FlexusX console. In the upper left corner, click and select a region.
2. Locate the FlexusX instance, choose More > Manage Disk/Backup and click Create Server Backup or Create Disk Backup in the Operation column.
   

   If the page for purchasing a backup vault is displayed after you click Create Server Backup or Create Disk Backup, the FlexusX instance has not been associated with a vault. In this case, associate the FlexusX instance with a vault first. Then, create a backup by referring to the steps described in this section.
