hammer: big file changes very often

Hi,
Ive just been thinking about this thing. what if i had a lets say > 1gb
database file which changes at least every 30 seconds. if sync is run
every 30 seconds, i would effectively create 2880 historical copies of the
same 1gb file every day. This would equal to almost 3TB of history every
day. I think its safe to assume that most people dont have 3TB of space.
How would you have to configure hammer to only keep one copy a
week(without creating 3TB of history every day) or not keep any copy of
this file at all?
