Any particular reason you're doing it that way?  The best way to run is to 
back up local disks, i.e. install the amanda client on the NFS server.

Take a look in /tmp/amanda/sendsize*debug on coil for more details, but 
I'm betting that you have one of 2 issues:

1) You're trying to use dump (rather than tar), which won't work on a NFS 
   mount.

2) You're trying to use tar and you have a root-squashing issue.  NFS 
   exports, by default, map root on the client (and amanda runs tar via 
   a setuid root wrapper) to nobody on the server.
