It can be + stacked on top of a "real" block driver, and catches all write + operations on their way from the file systems layer above to + the real driver below, effectively shielding the lower driver + from those write accesses. The requests are then diverted to + an ordinary file, located somewhere else (configurable). Later + read requests are checked to see whether they can be serviced + by the "real" block driver below, or must be pulled in from + the diverted location. More information and userspace tools to + use the driver are on the project's website + http://www.ATComputing.nl/cowloop/ |
