The organic design backups are created daily by User:Bender, compressed to .tgz and distributed over SSH to various other domains.
LZMA
LZMA is an extremely good compression method which compresses our backups to about one third of the size of the gzip or bzip. I have tested it with the free 7-zip file manager from www.7-zip.org and od-wiki-db-2006-11-20 is 268MB uncompressed, 54.9MB gzipped and only 21.7MB as a 7z! But I'm unable to get the Debian port to work due to dependency issues with low level C libraries that I don't want to mess with.
/home/nad# wget http://ftp.us.debian.org/debian/pool/main/p/p7zip/p7zip_4.43~dfsg.1-1_i386.deb /home/nad# dpkg -i p7zip_4.43~dfsg.1-1_i386.deb Unpacking p7zip (from p7zip_4.43~dfsg.1-1_i386.deb) ... dpkg: dependency problems prevent configuration of p7zip: p7zip depends on libc6 (>= 2.3.6-6); however: Version of libc6 on system is 2.3.2.ds1-22sarge4. p7zip depends on libgcc1 (>= 1:4.1.1-12); however: Version of libgcc1 on system is 1:3.4.3-13sarge1. p7zip depends on libstdc++6 (>= 4.1.1-12); however: Package libstdc++6 is not installed. dpkg: error processing p7zip (--install): dependency problems - leaving unconfigured Errors were encountered while processing: p7zip |
I've found a standalone version at http://sourceforge.net/projects/p7zip and that's compressed it to 24.8MB, not quite as small as the windows one, but still very good.
