Hello, I want to switch from DVDs as a backup medium to a usb flash drive. I have been using Mondo but get tired of feeding it DVD+RWs. I purchased a 128GB flash drive. I can't get Mondo to write to it. I want to be able to make this device bootable. Do I need it reformat it from a Windows file system to ext4? I never had to format a blank DVD previously. Is there a better solution for backing up a home system to some sort of external media? TIA
