(This may have already been posted.  Please excuse if so).

Taking a full dump is a pain in the neck.  Our VAX/750 has 2 Eagle dirves
and one 80 Mbyte removable drive.  It takes literally a whole day to take
a full dump of the entire system.  Even if I take a dump for one file system
at a time, it still requires more than 3 hours for a large partition (h or
g partition).  I would like to do the backup when the sytem is quiet.
So how do I squeeze in the few hours to do the backup?  Usually late at night
or in the weekends.  However, many folks on the system love to work at night
and on weekends/Sundays.  I guess I could shut down the system, but I would
rather do it otherwise considering that I have to shut down the system
for a few hours.

Has anyone out there with a much faster 'dump' programs, or a faster way
to do 'dump'?  I can see the existing 'dump' can be improved significantly
since the Cipher Tape is not streaming and most of the time, the VAX is idle
waiting for I/O. 

Any ideas, comments, pointers?   Please mail directly to me.  I'll summarise
if requested.

Thanks.
