Then I would expect the same ratio, since I believe zip and zlib both use the "deflate" algorithm. Note, however, that git will also do delta compression between versions. So storing N versions of a file should be no _worse_ than zipping and keeping those N versions. But if the database files have small enough changes from version to version (which depends on the database format, and how much the on-disk structure changes for each update) then it will compress even more. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
