Which VCS is efficient for storing small changes to big text files?

git

A government agency publishes a text file with thousands of records. The entire file is about 60MB. Every day the file has about 60 new or changed records.

We need to validate some info against that file, and for auditing purposes, we may need to recover the file as it was in certain date.

I thought I could use a VCS to store the file using git, but I understand git stores the entire text file gzipped, so the 60BM file will still need about 30MB to store everyday version.

I wonder if one of the free VCS stores only diff/patch files.
