required.

When saving the new data, any data previously saved in the
backup storage is overwritten (cannot be retrieved).
When restoring data or the factory settings, the current data
set in the device's main storage is overwritten (cannot be
retrieved).
When restoring data, certain bus settings and all texts set are
not overwritten and are therefore retained with their present
state. When restoring the factory settings, customized texts
are also reset.
