Puzzled here...
I'm using dump to backup to CDRW. If I do
dump -0 -B 665600 -f dump.dat /
I get a file dump.dat 650Mb in size. That gets burned to CDRW before dump
continues and uses the same file for the next bit. I can backup a 2Gb
partition in about 4 CDRWs. If I use dumps compression option thus:
dump -0 -B 665600 -f dump.dat -z9 /
I get a file dump.dat about 215Mb in size and dump happily announces that
it hasachieved 3:1 compression. But, I wanted dump to stuff as much
compressed data as possible into a _650Mb_ file! Id there something I'm
missing? I suppose I could use the tape length options to specify the
media size instead but it just don't feel right.
