Ok, now that's interesting... I'll agree that the fact that you're using
2.4.3b3 and aren't having problems indicates that you're right.
However... The comments in the amanda.conf file say:
"Note that the `full pathname' of a file within its
filesystem starts with `./', because of the way amanda runs
gnutar: `tar -C $mountpoint -cf - --lots-of-options .' (note
the final dot!) Thus, if you're backing up `/usr' with a
diskfile entry like ``host /usr gnutar-root', but you don't
want to backup /usr/tmp, your exclude list should contain
the pattern `./tmp', as this is relative to the `/usr' above.
Please refer to the man-page of gnutar for more information.
If a relative pathname is specified as the exclude list,
it is searched from within the directory that is
going to be backed up."
The man page says:
" For exclude list, If the file name is relative, the
disk name being backed up is prepended. So if this
is entered:
exclude list ".amanda.excludes"
the actual file use would be /var/.amanda.excludes
for a backup of /var, /usr/local/.amanda.excludes
for a backup of /usr/local, and so on."
These suggest that the exclude pattern, whether as a exclude pattern or a
file containing a list of patterns, is supposed to have *relative*
pathnames, not absolute pathnames. Yes, your list is relative, but your
path for the exclude list file itself is absolute
(/usr/local/etc/amanda/exclude.gtar) which is not quite what the docs
recommend....
I'll try some absolute paths later: if they work, it suggests a
documentation bug, rather than a coding one...
