Hello World!
	Hi.  We're having trouble with backups on a 9track.  We have two
3b2s (a 622 and a 700).  We have the tape unit on the 700 and ethernet
between the two.  We have /dev mounted under RFS on the 622.  The problem
is that the backups are taking FOREVER! (well, almost :-)  The backup of
the 700 machine uses 1 1/2 2400 foot tapes (at 6250) and takes over 2
hours!  The 622 requires more that 3 tapes (needless to say, it takes
several hours) and we have not been able to determine exactly how long
this is taking as we do not have staff here around the clock and it usually
has to wait 'til the next day to change tapes.

	Has anyone else had any experience with the 9track on a 3b2?  Our
contacts at AT&T say that the throughput should be much higher.  It seems
that the drive is stopping and starting as it writes (an indication that
the buffering can't keep up with the drive???) which means it has to back up
so that it can get the tape to the right speed at the right time.  Not exactly
a time saver!

	Please, any comments or suggestions would be welcome.  Send me email
or phone or whatever.

	Thanks
		Bill
