Keyword expansion is an opt-in feature. Subversion defaults to treating
file contents as opaque binary blobs to be preserved verbatim.

Anyway, in your situation, keywords aren't and won't be a factor.
Consequently you can use the server's precomputed checksum of the
content, which makes the implementation an order of magnitude easier.

60GB being the size of each revision of a single versioned file?
