Error description

• When running 7.1.x client on a SLES 12 host with BTRFS (B-tree
  File System) filesystems,
  "backup image" will fail to backup such filesystems with:
  
  Image backup of volume '/BTRFS_name'
  ANS1228E Sending of object '/BTRFS_name' failed.
  ANS8058E The specified path is a Linux Btrfs subvolume and is
  not valid
  for image backup.
  
  ANS1813E Image Backup processing of '/BTRFS_name' finished with
  failures.
  
  In this case, /BTRFS_name is a BTRFS 'root' volume and not a
  BTRFS subvolume.
  
  
  A service trace shows:
