I don't think so, but maybe someone else can comment. I don't think it
is possible to do this correctly with smb/tar since they have no way to
track deletions/moves/renames in incrementals (well, gnutar does, but
backuppc doesn't use that option).
If you have a linux box with more resources on the network, maybe it
would work better to NFS-mount the NAS instead of running backuppc on it
directly.
