Hi Nathan,

Thanks for your insights and help.

Ah, that explains it. Although it is somewhat confusing to not see that in
the config file at first.

I'm still seeing messages in the report that should have been squashed. It
also doesn't matter what I have configured as 'NORMAL' for the application
configuration.

  \--------

More configs:

DLE:
lambo.motec.com.au / {
        comp-root-amgtar
}

dumptypes:
define dumptype global {
    comment "Global definitions"
    auth "bsdtcp"
    exclude list optional ".amanda.excludes"
}
define dumptype root-amgtar {
    global
    program "APPLICATION"
    application "app_amgtar"
    comment "root partitions dumped with tar"
    compress none
    index
    priority low
}
define dumptype comp-root-amgtar {
    root-amgtar
    comment "Root partitions with compression dumped with tar"
    compress client fast
}
Application:

Note that this config setting:

define application-tool app_amgtar {
    comment "amgtar"
    plugin  "amgtar"
    property "XATTRS" "YES"
    property "ACLS" "YES"
    #property "GNUTAR-PATH" "/path/to/gtar"
    #property "GNUTAR-LISTDIR" "/path/to/gnutar_list_dir"
    property        "NORMAL" ": socket ignored$"
    property append "NORMAL" ": file changed as we read it$"
    property append "NORMAL" ": directory is on a different filesystem; not
dumped$"
}

AND this config setting:

define application-tool app_amgtar {
    comment "amgtar"
    plugin  "amgtar"
    property "XATTRS" "YES"
    property "ACLS" "YES"
    #property "GNUTAR-PATH" "/path/to/gtar"
    #property "GNUTAR-LISTDIR" "/path/to/gnutar_list_dir"
#    property        "NORMAL" ": socket ignored$"
#    property append "NORMAL" ": file changed as we read it$"
#    property append "NORMAL" ": directory is on a different filesystem;
not dumped$"
}

give the same results in the report.

Kind regards,
Tom
