Cowloop is a "copy-on-write" pseudo block driver. 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
