Hallo,
I have installed ftape 4.03pre2 on my 80486DX2/66 VLB. Could you
please tell me whether the writing speed is low or high?
The ft_fdc_rate_limit in my module insert script is 2000.
If I am doing a
tar -cvzf /dev/nqft0 /med --block-compress
the tape drive streams 253 MB uncompressed data in about 90 minutes.
If my calculation is correct this is about 380 kbps. The rate based
on compressed data is at about 250 kbps ( 167MB/90min ). I had about
50 write errors.
Verifying the backup with
tar -dvzf /dev/nqft0 --block-compress
takes about half the time (765 kbps uncompressed/ 500 kbps compressed).
My tape drive is a Iomega Ditto Max connected to the Ditto Dash DX
Accelerator card. Kernel : 2.0.33. OK, it�s stated in the manual
that you can�t reach 4 Mbps as it�s specified by Iomega, but
250 kbps sounds a bit low, doesn�t it?
What is your experience with the Ditto Max?
Stefan
