Backup

External media

Since I switch OSes frequently¹ having a minimum-hassle filesystem for my external drives would be very convenient. exFAT² seems to me like the best solution. In fact, exFAT is the default FS for SD cards and USB flash drives with more than 32Gb. So perhaps, if have a large-ish USB pen or an external drive, chances are you don’t even need to reformat it.
