Hi Stephen, sorry, I forgot to mention that my secondary storage is a QNAP device. Actually there is a way to install BackupPC on it:
http://wiki.qnap.com/wiki/How_to_install_the_BackupPC_application Anyway, I would prefer keeping configuration as much standard as possible. My choice is limited to QNAP daemon (NFS, rsyncd, samba).
