Hummm, why do I seem to detect the odor of a 2GB file size limit in your 
BSD filesystems?  I'd surely think this has been fixed, but I believe 
that number is 2GB-1 in decimal notation.

Selinux?  Or are you perchance running amdump as root?

First, and it might not be related, amanda is to be built by a normal 
user, preferably a user named amanda that you have added, and who has 
been made a member of the group disk (or backup, there are others too) 
that have enough perms to wander about the system.

Only the install is to be done as root.

Doing that will eliminate one potential list of perms problems.
