16.2. Backing up and restoring virtual machines

중요

Red Hat supports using OpenShift Virtualization 4.14 or later with OADP 1.3.x or later.

OADP versions earlier than 1.3.0 are not supported for back up and restore of OpenShift Virtualization.

Back up and restore virtual machines by using the OpenShift API for Data Protection.

You can install the OpenShift API for Data Protection (OADP) with OpenShift Virtualization by installing the OADP Operator and configuring a backup location. You can then install the Data Protection Application.

참고

OpenShift API for Data Protection with OpenShift Virtualization supports the following backup and restore storage options:

  • Container Storage Interface (CSI) backups
  • Container Storage Interface (CSI) backups with DataMover

The following storage options are excluded:

  • File system backup and restore
  • Volume snapshot backup and restore

For more information, see Backing up applications with File System Backup: Kopia or Restic.

To install the OADP Operator in a restricted network environment, you must first disable the default OperatorHub sources and mirror the Operator catalog.

See Using Operator Lifecycle Manager in disconnected environments for details.
