It's not written yet ;-)
When taking volume snapshot you have to 1) freeze data (without
blocking any applications if possible), 2) copy frozen data to
snapshot, 3) unfreeze data. In my code only step 2 is performed,
volume can not be modified while data is being copied.
This filesystem-specific code, that takes snapshot of a
whole filesystem or arbitrary object, can be arranged as external
utility and called when needed.
