I'm not sure about UFS support in Linux. You would probably need to
ask on a Linux list. The man page for newfs says that you can create
UFS1 filesystems with it, which may help with compatibility?
mount_ext2fs is available in FreeBSD but I can't speak for its
There is full read/write support for NTFS provided by
sysutils/fusefs-ntfs in the Ports tree. I suspect there are some
limitations though, eg. tighter restrictions than UFS on what
characters are permitted in filenames.
For making backups I would probably just use FAT32 and tar, because
practically anything (not just FreeBSD & Linux) will mount FAT32 file
systems, and tar should respect your file attributes (owner, group,
creation timestamp, last modified timestamp, etc).
