Abstract
A new approach is proposed that contemplates systems and methods to support quick recovery of an appliance by adopting a multi-layered filesystem having a plurality of layers that enables recovery and restoration of the appliance to factory default settings in seconds. In some embodiments, the multi-layered filesystem adopts a copy-on-write paradigm for all I/O operations to the appliance to create and superimpose an overlay layer by copying data from a read-only bottom layer of the appliance for modification and recovery of the appliance. The plurality of layers of the multi-layered filesystem are also tied to a general-purpose reset button or a software interface for implementation of an instant factory reset feature. When a reset signal is sent via the reset button or the software interface, one or more of the plurality of layers of the multi-layered filesystem are modified accordingly to provide a clean factory-reset of the appliance.
