It seems that you missunderstand reliability.
find | archiver
is a grant for inconsistence.
Using tar is gradually better but still not OK.
Do you like software for a toy environment or real reliable solutions?
It makes no sense to discuss religuous aspects like you try to do.
Rather thing abount constraints:
- Big backups and incrementals do not fit on a single DVD.
If you really like to use DVDs as media, use star -nultivol
- Small backups that fit on a DVD easily fit on intermediate disk space.
Note that you first need to think about snapshots anyway and snapshots
need disk space.
