Can copying a file damage the original?

Consider the following scenario:
* A database is accessing a large file $a on an Ext3FS, writing to it, reading
from it.
* While testing a backup script, the file $a is copied with rsync without
prior shutdown of the database software.
Here's what just happened under this scenario:
$a got damaged.
I'm certain that this is just a conincidence. However, my employer recalls
hearing other people stating that copying around files while copying them may
damage the original. I doubt that these other people have a clue, but
perhaps it's me who doesn't have a clue: Are there any circumstances under
which a source file in a copy operation can be damaged?
