Systems and methods for generating snapshots based on file inputs and outputs

Abstract

The present disclosure includes methods and systems for processing a file input/output (I/O). A method may include beginning, by a processor, copy-on-write snapshotting for a file stored in electronic storage; establishing, by the processor, a scope of authorization within a first layer using a first authorization callback function; determining, by the processor, if a read file that is being tracked is being opened for modification; and if the read file that is being tracked is not being opened for modification, ending the copy-on-write snapshotting, or if the read file that is being tracked is being opened for modification, marking the file as a subject of the copy-on-write snapshotting and then ending the copy-on-write snapshotting.
