Problem

During a physical server backup job, an error message appears informing that the source server contains unsupported volumes.

Background

Windows OS

On Windows, NAKIVO Backup & Replication supports only the following dynamic volume types:

  • Simple volume: This is a portion of a physical disk that functions like a separate unit. It can consist of a single region on a disk or multiple regions of the same disk that are linked together.
  • Spanned volume: This combines areas of unallocated space from multiple disks into one logical volume.
  • Striped volume (RAID-0): This is created by interleaving data across two or more physical disks. The data on this type of volume is allocated alternately and evenly to each of the physical disks. Striping is also known as RAID-0, which stripes data across multiple disks.
  • Mirrored volume (RAID-1): This is a fault-tolerant volume that provides data redundancy by using two copies of the volume to duplicate the data that is stored on the volume. Mirroring is also known as RAID-1.

Use the Disk Management tool to view and manage your dynamic volumes.

Linux OS

On Linux, NAKIVO Backup & Replication supports only the following LVM logical volumes:

  • Linear volume: This is a logical volume made by combining multiple physical volumes to one.
  • Striped volume (RAID-0): In a stripped logical volume, data in the underlying physical volume is stripped across the number of physical disks.  
  • Mirrored (RAID-1)These logical volumes are similar to RAID-1 in which data is mirrored across the number of disks to provide better redundancy for the data.

Use LVM CLI commands to view and manage your LVM logical volumes. 

If your physical source server contains other types of dynamic/logical volumes, the following error message appears when you start a physical server backup job: “The server contains unsupported volumes”.
