note that there's a lot of things where file by file, or even sector by 
sector, duplicates are NOT valid if made while the system is online.

for instance, relational databases such as PostgreSQL, Oracle, you can't 
just copy their files while the database server is running, as they rely 
on writes being made in a specific order.
