I remember distantly that last time I tried with FFS, it didn't work. I assume NFS/scp/rsync is out of the question? I've successfully used FreeBSD FFS partitions in NetBSD, after adjusting the MBR partition type (A5/A6/A9) and disklabel (renamed sd0d to sd0h since NetBSD uses sd0c for the entire BSD MBR partition and sd0d for the entire disk), so I would expect it to work with these adjustments, but it is by no means guaranteed (this was several versions ago), and caveat emptor applies. tar is good and simple if you're restoring the whole thing right away, but if you want to easily get various individual files out of the backup or rearrange the structure, rsync to ext2 (or ffs, maybe) would be better.

Personally I would just try to tar to the usb device and skip having a filesystem on the usb device; that way there is no filesystem to be incompatible. Such a simple and elegant solution. Having never done this before I just tested it. Very slick.

Great idea. Thanks, that should do the trick. this assumes that NetBSD tar and split are substantially similar to OpenBSD's. I'll report if I found it doesn't. Cheers! -- Étienne

NTFS (built-in, or FUSE) has its own owner/mode translation issues, such that you would liely want to archive files as intermediate step. Of course, network file transfers, if you had the bandwidth, would preclude the need for any foreign file systems.

Or use FAT, but put all files in one or serveral tar archives. In that way, file type, ownership and permissions would be saved.
