So what filesystem is safest to run over USB?
Frankly I don't know. Like Mr. Mikesell I've had good experience with the tools for EXT4, but my wife has managed to trash at least one EXT4 partition by simply plugging a USB device into a powered USB hub which at the time happened to be supporting the USB disc drive on a Pi4B. Unfortunately the recovery tools failed in that case (and in fact they seemed to compound the problems). Fortunately the drive itself didn't seem to have been damaged, and the loss was limited primarily to our convenience copies of about a thousand movies. No small loss of her time copying them I'm afraid. See also https://en.wikipedia.org/wiki/USB_mass_storage_device_class#Design which explains one reason to be very cautious about what you do with your drives if they're connected via a USB interface. There's often no obvious way to find out what commands the interface supports other than trial and error, which could work out expensive. -- 73, Ged. _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
