Backup & Restore should allow the administrator to backup/restore only selected settings (e.g., DHCP IP Address Reservations, IP & MAC Bindings, TP-Link login credentials, etc.), via checkboxes, when creating or loading a backup file. The current file is not readable via a text editor such as Notepad++ so there is currently no way to edit what you backup or restore. It's currently all or nothing. This should be fixed ASAP.
