US Patent 12072774 Backup and restore via union mount filesystem

An information handling system may include at least one processor and a memory. The information handling system may be configured to store a first set of data comprising an operating system in a first location; store a second set of data comprising application data in a second location; expose the first and second sets of data in a combined union mount filesystem; and create a backup of the second set of data, but not the first set of data, by creating a copy of the second location.
