I'm assuming you are using tar (since I don't think you can use dump on an NFS mount). Amanda uses the runtar wrapper script, which is suid root so that tar can run as root (since tar accesses via the filesystem it has to run as root to access all the files). Most OS's map NFS access requests from UID 0 (root) to nobody or some other non-root user for security reasons. You probably need to change your export options on xtreme23 to include the no_root_squash option (or whatever its called on the NFS server's OS) for the export to the Amanda server so that root on the Amanda server has root access to /xtreme23/scratch, so tar can see all of the files.
