bzip is much slower than gzip, a lot less widespread, and doesn't yield
substantially better compression ratios on the vast majority of data. so
why bother?

Hi all,
I'm considering backing up to bzip2 instead of gzip (.tgz) to pack more on a
single DVD. I'm getting close to 2 full DVDs, and I'd hate for my backups to
span 3.
So in other words,
tar cjvf mybup.tar.bz2 mydir
instead of
tar czvf mybup.tgz mydir
My question is this: 20 years from now, will it be trivially easy to find
software to decode bzip2. I'm sure it will be trivially easy to decode
gzipped tars -- that's been a standard for years and years. Is bzip2 here to
stay, or will it be dropped as years go by?
I'm serious about this. I often look at computer programs I wrote in 1984. I
still regularly use Micrografx Windows Draw drawings I made in 1992 (this
remains my one major reason for keeping a Windows machine around). Will
tar.bz2 be decodable in 20 years?
Thanks
