On a test machine with a good cross-section of activity documents, I
gzipped all the files in the datastore directory. Only 6% storage
savings according to the gzip stats - higher if I only look at the
metadata files (avg 12%). Several files had negative compression

So your suspicions seem correct - compression is a marginal win at
best for ds-backup.
