We use Ubackup here where we work and we are very pleased with it.  The
biggest problem we have had with it is the documentation (which has been
re-written for the next release I've been told).

As to the tape format, Ubackup will use *either* tar or cpio.  You can
change the format with a simple change to a config file.  You can also
specify the blocking factor to increase tar performance if your drive
can use large tape blocks.  We use a blocking factor of 126 and it cut
our backups to about half the time (TK50's on MicroVAXen...SLOW!).
