Apology & backup
Hong F Du
If you received an unfinished message before this one, please accept my
apology for accidentally sending it.
I am planning to install a PCI SCSI controller and a external backup
drive on my Pentium 90 machine with Redhat 6.1. But I don't know what
brand and model of hardware I should buy. Could you please give me some
recommendation? It would be better if you had setup something like that
before and like it. Thank you.

As far as the SCSI adapter is concerned, I have had a Tekram
DC390 and a DC390F and I'm happy with both. If your external
backup has a 50-pin SCSI connector, go for a DC390 or DC390U.
If it's a 68-pin connector, pick the DC390F or a better model.
Don't try to plug a 50-pin device to the external connector of
a DC390F, it won't work. :-(

Because it's external, you can use it for more than 1 PC.
The costs/bit for 120m DDS2-tapes is very low. :)
(4GB for USD 10)

One problem: That solution is likely to cost many times what a P90
computer is worth.
I could probably get a P90 PC for about USD 200; a tape drive costing
five times as much as the computer is not going to look like a terribly
good value.
That being said, there are few _cheap_ alternatives. Pricing of
CPUs, memory, and disk drives have made for "low, low prices,"
meaning you can readily get a PC for USD 500 that is pretty usable
at least for desktop purposes.
The increases in functionality and decreases in pricing for tape drives
have not been _nearly_ so aggressive.
<http://www.tdl.com/~netex/data/dat.html> lists a variety of
backup devices and relevant pricing:
-> Ecrix VAX-1 tape drive (around $1000 for a 66GB SCSI-2 tape drive)
-> DLT 40/80 GB tape ($1400-$1500)
-> OnStream IDE/SCSI Tape Drive: 30-50GB ($310 for 30GB IDE, $690 for
50GB SCSI)
-> DDS-4 4mm DAT - 20GB ($1250)
-> DDS-3 4mm DAT - 12GB ($900)
-> DDS-2 4mm DAT - 4GB ($550-$600)
-> DDS-1 4mm DAT - 2GB ($540)
-> AIT AME 8mm tape - 25GB ($2250)
-> Travan TR5 10GB Tape ($340 IDE, $450 SCSI)
Pricing is pretty daunting for many of these.
There are parallel port options, priced to sell to home PC users;
those solutions tend not to be of high reliability.

"...In my phone conversation with Microsoft's lawyer I copped to the
fact that just maybe his client might see me as having been in the
past just a bit critical of their products and business
practices. This was too bad, he said with a sigh, because they were
having a very hard time finding a reporter who both knew the industry
well enough to be called an expert and who hadn't written a negative
article about Microsoft." -- Robert X. Cringely

I normally go for
SCSI: NCR-875 U2W (dead cheap, perfect performance and suport,
faster than any tapedrive needs), about USD 100.
Tape drive: HP DDS3 or better, about USD 1000.
Or did you mean an external harddisk backup drive?
