      ERROR taper no-tape [No writable valid tape found]
      WARNING taper writing label: tape is write protected

      Resolution

      1. Please check the permissions on the tape device. These are the correct permissions:

      [root@bugs dev]# ls -al /dev/nst0
      crw-rw---- 1 root disk 9, 128 Jan 12 01:59 /dev/nst0

      2. Make sure that the "amandabackup" user belongs to the "disk" group. 

      [root@bugs dev]# grep disk /etc/group
      disk:x:6:root,amandabackup
