If you are happy using TAR for doing Amanda backups on
the Netapp, I'd like to try the same on my backup
host. Since my Netapp is at about 90 Gb usage with one
of the mounted directories close to 50 Gb, backups
using dump/restore fail for the Netapp.

Here's a skeleton for disklist how to break up your large
filesystem into smaller pieces using gnutar to do the backup.
Since amanda 2.4.3 you can modify the dumptype inline
in the disklist; we modify the dumptype by adding some exclude
patterns to the dumptype.  We work up in the tree, listing
large objects, and excluding them from the level above.

  # A very big directory
  your.host  /filer/home/john/pictures    comp-user-tar  1

  # The rest of the files and directories from john
  your.host  /filer/home/john {
                comp-user-tar
                exclude append "./pictures"
                }  1

  # Two big directories
  your.host  /filer/home/paul/music       comp-user-tar  1
  your.host  /filer/home/paul/bigproject  comp-user-tar  1

  # The rest of files an directories from paul
  your.host  /filer/home/paul {
                comp-user-tar
                exclude append "./music"
                exclude append "./bigproject"
                }  1

  your.host  /filer/home/george           comp-user-tar 1

  your.host  /filer/home/ringo            comp-user-tar 1

  your.host  /filer/home  {
                comp-user-tar
                exclude append "./john"
                exclude append "./paul"
                exclude append "./george"
                exclude append "./ringo"
                }  1

  # all the rest
  your.host  /filer  {
                comp-user-tar
                exclude append "./home"
                }  1

(We assume your netapp is mounted under /filer, so we stop here.)
