Anyone else here subscribe to the LINUX JOURNAL? In the September issue there's a neat article titled tha same as the subject line of this message.
The skinny is, there's some really nice file compressors out there and I never heard of two of them... Anyone else know about LZMA or 7ZA? The two mentioned compression tools work pretty much like gzip. You tar up your files, pipe to the compression filter and then on to the target file. Below is a small example of what I've been seeing here at the shack. -rw-r--r-- 1 root root 12359680 Aug 12 23:57 backup.tar -rw-r--r-- 1 root root 3536665 Aug 13 00:01 backup.tar.7z -rw-r--r-- 1 root root 4438465 Aug 13 00:08 backup.tar.bz2 -rw-r--r-- 1 root root 4747637 Aug 13 00:03 backup.tar.gz -rw-r--r-- 1 root root 2731412 Aug 13 00:10 backup.tar.lzma -rw-r--r-- 1 root root 5125474 Aug 13 00:16 backup.tar.lzop What you're seeing are the results of compressing /lib on my gentoo powered laptop. I've not bothered with timing the processes as the better compression rates are at the cost of speed and memory usage. Not good for "while you wait" processing, but just plain perfect for backups and what-have-you on servers... One side note, 7za does not record user/group info... It's a shame too as this make it pretty much useless in most linux backup scenarios. This lzma creature is simply awesome.
