I guess but may be terribly wrong that system doesn't return the command's stdout but an exit code. On top, the awk you supplied is wrong in (at least) two ways: it needs its data supplied in files, e.g. stdin, not a variable, and the field count doesn't fit. 3206000 is field 6.
Why is it you can't extract that value in perl ?

AMARCHIVER(8)						  System Administration Commands					     AMARCHIVER(8)

NAME
amarchiver - Create, extract or list amanda archive SYNOPSIS
amarchiver --version|--create|--extract|--list [--verbose] [--file file] [filename]... DESCRIPTION
Amarchiver manipulates amanda archive file. On creation, amarchiver doesn't recurse into directories. If a filename specifies a directory, it will be ignored. If it specifies a character device, amarchiver reads the device and archives the data. If a filename specifies a named pipe, amarchiver reads the named pipe and archives the data. Note that this tool is more limited than the Amanda archive library, and may not be appropriate for some archive files -- particularly those which use non-strings in their filenames. OPTIONS
--version print the amarchiver version --create Create an amanda archive. Only the supplied filenames are included. With one --verbose, lists the filenames. With two, lists the filenames and sizes. --list List the filenames in an amanda archive. No additional filenames are allowed on the command line. --extract Extract an amanda archive. If filenames are supplied, only those files are extracted. Files are created in the current directory, suffixed with a dot ('.') and the attribute ID. --verbose Give more information. --file file Create, list or extract from the given file instead of stdin/stdout.
