This doesn't need to be turn into a fight people, but let me say this -
When you buy software or what have you, you are typically purchasing a license of use. In order for your license to be valid, you are required to adhere to the EULA. If your EULA or similar statement or agreement states that you cannot make backups lest your license be invalid
it doesn't matter what your counties copyright laws are, your license is invalid and it officially becomes piracy.
A quick look at Titan Quest for PC's EULA shows no specific condemnation of making backups, only stating that if you give the game to someone else, you aren't allowed to keep a copy.
However, the LIMITED SOFTWARE WARRENTY AND LICENSE AGREEMENT for Grand Theft Auto: Liberty City Stories for PSP gives you license to ONE copy. If you make a backup, it is not licensed to you (unless you destroy the original) and is illegal. It goes on to state clearly that you are not to make copies of the game, nor are you allowed to back it up to your hard-drive.
Remember, you don't own the software, you own a single license to use it. If that license is revoked
you own nothing at all and have no rights to the software.
What I'm saying is that due to the nature of software licenses, if the license agreement says you can't back it up, then you simply cannot back it up.
In fact, license agreements typically
give you rights that would otherwise be prohibited by copyright and trademark laws. U.S. copyright
does allow for you to make copies of software, (
http://www.copyright.gov/title17/92chap1.html#117) but if you agree to a license agreement that states otherwise, then you wave that right. Also, please note the wording of the law:
This means that, EULA not withstanding, you can make a copy but you
may not use that copy unless the original disk or whatever is destroyed. .
Bottom line? Contracts can supercede copyright law. If it says you may make backups in the EULA or Software Agreement, then you may, but only in the capacity stated in said agreement. If the Eula or Software Agreement says you may not make copies, then you may not. If it doesn't say anything about it, then you may archive it.
Simple as that, really.
