Using ULTRIX to back up other UNIX systems using NFS

[Fred Ross-Perry]

We are considering using an ULTRIX machine on our network to back up other
ULTRIX and UNIX systems.  The systems would run whatever NFS was available,
serving their disks to the ULTRIX system which would tar or cpio their files
to tape.  Has anyone had experience in this area?  Are all NFS servers equal?
Are there security problems, or problems with differing configurations?  
How does one restore and boot from an entire disk?

Thanks in advance,
