VrBackupper is a free Windows software designed specifically for the Oculus Rift virtual reality device.
It allows you to migrate the Oculus installation to another location, or to back up or restore the Oculus installation directory.
The program is dead easy to use. It detects the Oculus directory automatically on start, and lists the two options migrate or backup/restore in the main interface.
While there is usually no need to back up virtual reality data, the migration option may prove useful.
