Abstract
Some embodiments provide a system that provides a filesystem in a computer system. During operation, the system obtains a policy for the filesystem and separates the filesystem into a set of layers based on the policy. Next, the system processes input/output (I/O) operations to the filesystem by directing each of the I/O operations to one of the layers based on the policy. Finally, the system periodically maintains the layers using a master image of the filesystem.
