You will face two other problems once you get it actually running:

* You won't be able to use it as a device server, since Tapeware sends
  raw SCSI requests to /dev/sg* on Linux.  The equivalent for FreeBSD
  would be to use /dev/pass* devices, and there is no emulation layer.

* Linux emulated programs always search /compat/linux/ before /, so if
  you ask to have "/bin" backed up it will back up /compat/linux/bin
  instead of /bin, for example.  I don't know if there is a useful
  workaround, since Tapeware is smart enough to not follow symlinks
  (otherwise you could ccreate a symlink at /compat/linux/realroot
  pointing to /, and ask Tapeware to back up "/realroot")

Tapeware is great software, but I don't think they are a large enough
company to be able to maintain a port to FreeBSD.  I think you can tell
Tapeware to back up NFS mountpoints, so you might be able to back up
the FreeBSD system by mounting it from another Linux box (or a Windows
one if the BSD one is running samba)
