No, the archive you get from a full will be identical to the archive you
get from an "incremental". The term "full backup" and "incremental
backup" is only of interest during the data transfer phase from client
to the BackupPC server. After that, all backups are treated (almost) the
same with "gaps" in incrementals being automatically filled from the most
recent incremental or full.
I'm using the archive feature with a custom script to get archives on
tape - the script checks which hosts to archive (based on last archive
time), then creates the archive. When the script is finished (it's got
an enforced timeout), Bacula picks up the archives and writes them to
tape.
HTH,
Tino.
