I have a large image file (159GiB) I want to compress and split before burning to several DVDs. I'm testing the shareware version of rar, which has automatic split on a given size, plus addition of error recovery data, which is nice. More or less, I use:
rar a -rr -rv -v4589808k sda2 sda2.img
which produces (slowly, about 45 minutes per 4.4GiB file) 8 files named like sda2.part01.rar to sda2.part08.rar, plus one sda2.part1.rev.
It is slow, disk is busy at only about 2MB/s, or about 20..30MB/s on the empty regions of the image. It only uses one core of the cpu. I recogn I have not used rar since about 1997 (when I started using linux), but I don't remember it being slow. Of course, the file I'm compressing is very large...
I wonder if there are opensource compressors with similar features?
have a look at dar and kdar or dargui dar is excellent for archiving and splitting into dvd/cd sized chunks. I use it for all my local archival purposes. And it is available for other operating systems. -- Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 @ http://counter.li.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
