It has a 207MB disk and a 2MB floppy drive. This sort of thing must be a fairly common problem, and I wonder what other people are doing about it. So far I've had the following ideas, listed most expensive first. Prices are just guesses, as I haven't gone shopping yet. Buy a DAT box for about $2500; media cost is about 1.5 cents/MB. Buy an 8mm tape box for about the same price; media cost is about 0.4 cents/MB, which seems much better than the DAT. Buy a QIC-150 box for about $1200; media cost is about 25 cents/MB. Back up onto floppies using dump and restore. 100 floppies, ouch! Not only is it amazingly tedious, the media cost is 120 cents/MB. Wouldn't I need about $500 worth of floppies to do it right? Back up onto floppies using bar(1). This makes full dumps smaller, because bar can use compression, but it doesn't support incremental dumps. Back up onto floppies using GNU tar, because it supports incremental dumps and I think multivolume dumps, but I don't remember whether it supports compression. Don't back up the root and /usr filesystems, except for the few odd locally changed files like mailboxes; restore these filesystems when needed by borrowing a CD-ROM drive from work. This should cut backup size by a factor of two at least, but it requires a careful enumeration of all locally modified files. ------------------------------ Date: 5 Feb 91 8:11 -0600 From: Sharkey Subject: Hard Drive Advice Needed. To: Hi all, I'm new to the Sun world having just purchased a Sun 2/50 with 5 megs and a SCSI controller I now have the dilemma of get Hard Drive space for the beast. I will be running OS 3.5 for now. How much drive space do I need? Where can I find sane prices. I would guess that a used shoebox would be my best bet am i correct?

How will it survive is I throw X11R4 and 1-2 >X terms on it? Thanks in advance. I have no experience with the SLC serial port. I have it hooked to my home ethernet. It works fine with a Wren VI--I just told the system it was a Sun 676mg disk. With 16mb of memory, it's quite fast. One or two xterms won't even make it breathe hard. ------------------------------ Date: Mon, 4 Feb 91 17:32:19 CST From: Ron Olphie Subject: Sun-2 Resale Companies? To: suns-at-home@orchestra.ecn.purdue.edu I have a need for 1 or 2 Sun-2s plus extra cpu and memory cards. I know almost nothing about the Sun-2 product line, but what I'm looking for is a multibus systems with several slots. I "think" I'm most interested in the Sun-2/170. Any information about Sun-2 resalers and your experiences with Sun-2 would be welcome. Thanks, Ron Olphie ------------------------------ End of Suns-at-Home Digest ******************************
