Vic —
I have an RByte-100 4mm DDS drive mounted internally in my PC. It backed up
and verified 448,662,740 bytes (428MB) in 1 hr 33 mins. Assuming equal time to
do the write and read back (and ignoring rewind time), that works out to
157KB/sec, or almost twice as fast as I can transfer data over my network.
Copying a 3MB+ file from the PC to the Amiga under NFS transfers data at
79KB/sec.
Since the PC has the preponderance of data (380MB to 68MB), I decided to
install the tape backup there. I suppose that I can call the company that I
got the drive from and get an external box for it so I could mount it on my
Amiga. Don't ask me what I want to reserve the 5.25 slot in the Amiga for, but
I might need room for something in the future.
Thanks for your suggestion to mount the tape drive on the Ami. Since the
backup runs at midnight, I don't really care how long it takes, so it's not
important where the tape drive is mounted.
However, it's a real PITA to have copies _to_ the PC take 8-9 times as long as
transfers _from_ the PC.
Writing a file from the Ami to an NFS partition on the PC transfers data at
8-9KB/sec
Writing a file from an NFS partition on the PC to the Ami transfers data at
79KB/sec
An NFS put to the PC transfers data at 68KB/sec
An NFS get from the PC transfers data at 86KB/sec
I _really_ want to know where the problem is. I guess that I would have been
an EE if I weren't a programmer. The worst part of it is that it isn't _my_
code. If it were, I would know how to fix it.
