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 reliability. 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).
