Well, I have no control on how the user transfers back and forth among
machines.
Imagine you have a zip file where you backup your daily work. After
you've done your backup, you put it on a pendrive and go home. When
you're at home you copy this file to your computer and decompress it.
Our application works exactly the same way, except that it does not work
with raw files, but with PostgreSQL data.
So I don't know how a user handles its backup files once he has made his
backup...
