Feature Limitations

NAKIVO Backup & Replication features require certain conditions to function properly. For more details about feature requirements, refer to the corresponding articles in the User Guide. Below is a list of feature limitations. 

Backup and Replication

  • VMware VM RDM disks are supported only in virtual compatibility mode.

  • Cluster Shared Volumes (CSV) are not supported for backup of physical systems.

  • Windows failover clusters are not supported for backup of physical systems.

  • Backup and replication of Microsoft Hyper-V VMs with shared drives are not supported.

  • Linux Transporter should be used for replicating/backing up VMs with SATA disks.

  • When copying a compressed backup between a Backup Repository and tape device, different compression levels may cause very slow transfer speeds. For more information, see this article.

  • Windows dynamic disks are not supported.

  • Physical machine backup is not supported.

  • Linux swap files are currently not excluded. Only Linux swap partitions are supported.

vSphere HotAdd

  • If HotAdd cannot be enabled for at least one disk of a source VM (even if the disk is deselected in the job), HotAdd may be unavailable for all disks of the VM.

  • HotAdd is not available for VMs that contain IDE disks.

  • VMware vSphere HotAdd is not supported if the VA with NAKIVO Backup & Replication has the same BIOS UUID as the source VM.
