[ale] tape backup of homenet

[Dow Hurst]

The DDS3 drive that I have is a SCSI based, SGI purchased drive.  I
don't know what an open market price would be but it was around listed
around $1875 I think on the invoice.  We get a 35% to 45% educational
discount so it is hard to guess at what you might pay.  Also, the drive
really isn't the latest technology like it was when we were getting our
Origin 200 server either.  I personally like the DDS3 format since you
can get 25Gb on one tape which costs about $25-$30.  Higher densities
are available now for tape but I am not familiar with the newer stuff.
