Just an FYI..
My recent backups of some of my DataStage projects have been around a gigabyte in size. Aside from 'chopping' the extracted DSX file and versioning the individual jobs in Subversion I have also been saving a zipped copy of the DSX file, just in case. Recently I tried 7zip because I wasn't able to hold all my backups on one DVD using ZIP.. here are the results of my test:
ZIP 55 MBytes ~ 17 times compression
7zip 12 MBytes ~ 82 times compression
7zip compression of a DSX file.
