| That depends on your backup requirements. Do you want to be able to
| data if your house burns down? Do you want to be able to recover
| data that you inadvertently corrupted 6 months ago? How frequently
| do you want to back up your data?
| For small amounts of data, a CD-R or CD-RW drive may be attractive. For
| larger amounts, a tape drive is the obvious choice but has some issues.
| A removable hard drive is a good choice if you only plan to keep a
| small number of backups; otherwise the price gets exorbitant.
| For a home system, there are only two types of tape drives to consider;
| Travan and DAT. Travan is less expensive for the drives, but the
| tapes themselves are very pricy. DAT drives cost more, but the tapes
| are less expensive. For a business computer, there are other types
| of drive worth considering, e.g.. DLT.
You can also consider Ecrix VXA-1 and VXA-2 drives. They are much more
reliable than DDS-2 DAT drives (these are not the only DAT drives, and
it is my understanding that DDS-2 drives are no longer manufactured).
VXA-1 drives are about $750 these days. I use a VXA-1 on an Ultra-2 SCSI
controller here at home. I am very serious about backups, though, having
seen a lot of disasters since computers started getting hard drives. The
first hard drive I ever saw was an IBM 2311, I think: 10 platters, 100
cylinders, hydraulic actuators. Probably held about 10 megabytes. They
had much bigger drives pretty soon afterwards on the IBM 7090 machines,
and it has been uphill ever since.
| A lot of people like backup devices on a parallel port or USB bus. I
| understand the convenience factor, but there are driver and performance
| issues. My preference is SCSI, but that costs more than IDE. There
| is no one size fits all, but almost any backup solution is better
| than not taking backups.
It seems to me, with no proof, that devices manufactured for SCSI
interface tend to be more reliable than the floppy-disk controller
drives, for example. I believe that the assumption is that those who run
with SCSI controllers are more likely to have serious requirements, so
the stuff is made somewhat better (and priced accordingly, of course).
I agree that SCSI is the way to go if you can afford it. I can backup,
rewind, and read-check about 6.5 gigabytes in about an hour, and my tape
drive is penalized by being on the same controller as the two hard drives.
