If I do an initial, complete backup but then don't open/change a file for months (e.g. some old photos), but also don't delete them from my laptop, will they still be available in Time Machine after it deletes the initial backup due to space?  If it's only updating files that have changed, how is it ensuring that my unchanged files are backed up after it deletes the initial, complete backup when my external hard drive gets too full?  Thanks.

MacBook Pro (13-inch Late 2011), Mac OS X (10.7.3)
