Last access is generally considered to be reading the file but as Kan 
has pointed out previously, it is so unreliable as to be virtually 
useless. Depending on the OS, copying a file will change the last 
access time and it can be changed by something as trivial as viewing 
the file properties e.g. the last access time displayed by explorer 
under NT is always the current time. Certainly carrying out a backup 
could be responsible for changing the last access time.

In reality, you can only use the last modified time as a reliable 
test and try as best you can to exclude static files which are 
accessed regularly but don't change.
