NetBackup™ for Red Hat Virtualization Administrator's Guide

Things to know before you protect Red Hat Virtualization virtual machines

  • You cannot backup the same Red Hat Virtualization VM concurrently.

  • The VMs without virtual disks cannot be protected.

  • The following QCOW2 image attributes are not supported:

    • Compressed cluster

    • Encrypted disks

    • Virtual disks with internal snapshots

  • If the VM virtual disks are locked when the NetBackup services shutdown or crash during a backup, use Red Hat Virtualization's unlock_entity command to unlock the disks. If the disks are not unlocked, the subsequent backups might fail.

    See Error run into while backing up Red Hat Virtualization virtual machines.

  • On a file storage (NFS), a QCOW2 disk gets restored as raw disk (thin provision) because of an Red Hat Virtualization limitation.

  • A thin dependent cloned VM is restored as an independent cloned VM.

  • If you want to use a storage that is not available through the NetBackup Web UI like a tape or basic disk based storage unit, you can use APIs or command line options to protect the VMs.

  • For the minimum permissions required to perform VM backup and restore, see https://support.cohesity.com/s/article/article-100050733
