FAT (and FAT32) would probably involve less experimentation. to bypass the limitations of FAT, I recommend using tar(1) and split(1).
tar cfC - /filesystem-to-back-up . | split -b 2000m that will produce a tar file split into 2GB chunks named xaa, xab, xac, etc. to restore: cat x?? | tar xfC - /directory-to-restore-into . this assumes that NetBSD tar and split are substantially similar to OpenBSD's. -ken On Sun, Mar 1, 2015 at 11:55 AM, Josh Grosse <j...@jggimi.homeip.net> wrote: > On 2015-03-01 11:40, etie...@magickarpet.org wrote: > > Could anyone recommend which filesystem type to use when backing up a >> few hundred GB of files from NetBSD onto a USB disk, planning to >> restore them on an OpenBSD machine.
