I have recently added an Orange Livebox ADSL router to my LAN (as an additional WiFi Access Point) and also as a network disk server.
This is an Arcadyan router rebadged by Orange for the Spanish market. It supports FAT32 only.
I can write to and read from data sticks plugged into the router's USB port from my Linux laptop using
I am thinking of buying a USB disk to act as a network server so that I can backup my files from Linux and maybe also from MacOS etc.
I am familiar with unmounting USB data sticks attached to my laptop in order to flush all written data to the device.
Is there something I can use to make sure that my router also would flush all the data to its disk?
The router gets rebooted from time to time and there are occasional power cuts.
