I reckon the only way to do backups is to have backups built into the file-system.
Such an example that springs to mind is the Plan 9 file-system, which is a cached
WORM jukebox employing both a memory and magnetic disk cache.  Backing it up
causes a snapshot of the file-system to be written to the WORM.  The file-system
stays usable for the duration of the backup via a copy-on-write mechanism, so
there's no availability or consistency problems.
