As a concept, an incremental stores the differences between the actual status and the last full backup, so a full must exist first, yes.
You select what to backup defining at least a share. How you do it depends on what method you use ("the underlying transport program").
The following examples defines multiples shares:
$Conf{SmbShareName} = ['c', 'd']; # backup 'c' and 'd' shares$Conf{TarShareName} = ['/home', '/src']; # backup /home and /src
$Conf{RsyncShareName} = ['/', '/var', '/data', '/boot'];Only one share could be, for samba, just $Conf{SmbShareName} = 'c';
Then you may refine your choice with $Conf{BackUpFilesOnly} or $Conf{BackupFilesExclude} directives (but not both at the same time, at least for samba). See http://backuppc.sourceforge.net/faq/BackupPC.html#item__conf_backupfilesonly_.
Something like a share '/my_test_dir' and $Conf{BackupFilesOnly} = 'my_test_file.txt' could be what you are looking for.

Assuming that the first backup is 'full' I want, as a test, to specify one file in one directory to be backed up. Where do I specify how to do this? In the 'my_machine.pl' configuration file? Using the $Conf{BackupFilesOnly} = '/my_test_dir/my_test_file.txt' I assume?
I guess the real question is, anytime backup is run, it ALWAYS uses the $Conf{BackUpFilesOnly} directive and the $Conf{BackupFilesExclude} directive to dictate what gets backed up or not?
Thanks for the clarification
