    From the GNU info doc on the tar program:

    Metadata stored in snapshot files include device numbers, which,
    obviously is supposed to be a non-volatile value. However, it turns
    out that NFS devices have undependable values when an automounter gets
    in the picture. This can lead to a great deal of spurious redumping in
    incremental dumps, so it is somewhat useless to compare two NFS
    devices numbers over time. The solution implemented currently is to
    considers all NFS devices as being equal when it comes to comparing
    directories; this is fairly gross, but there does not seem to be a
    better way to go.

    This to me, seems to be another borkage of the tar program. Can you
    tell Amanda to use 'dump/restore' instead of tar instead? Or heck,
    just move to Bacula, it's smarter than amanda/tar and it supports
    writing to DVDs, etc.

    This tar borkness is pretty annoying, since Amanda (from the docs
    page) only keeps indexes in terms of host/filesystem/path/date,
    nothing about the major/minor (device) numbers.

    It just re-inforces my desire to never use Amanda again.
