Setting volume size for dump
Thank you for the reactions to my enquiry about efficient backup programs.
I have overlooked dump and am trying it out now. What I do not seem to
get right is setting the volume size. While using dump like this:
dump 0uf /dev/nzqft0 / it does a backup, but says it requires 11
tapes asking every now and then for the next volume.
I tried dump B 1796 0uf /dev/nzqft0 / and dump -s 108700 0uf /dev/nzqft0 /
but in both cases dump complains and does not accept the parameters.
A dump on /dev/rmt8 results in a large file with the name /dev/rmt8 taking
all the free space on my hard disk.
My questions :
1. How can I tel dump to use all the available capacity on my tape?
2. How can I change dump's default device to /dev/nzqft0?
3. In setting the volume size, how can I correctly bring the compression
factor of using zftape into account?
Johann.
