Time Machine

Hi all,

I feel incredible frustrated for not knowing, but I'm not great with Macs in general and appreciate any help. I backed my computer up on my external hard drive via Time Machine and wanted to verify that the iphoto library was backed up as well. Here is the progression after I clicked on the Time Machine icon:

Macintosh HD --> users --> cl --> pictures --> iphoto library

When I go to the iphoto library I get the message "The iPhoto Library is a Time Machine backup, and so cannot be used as the main library. Relaunch iPhoto with <option> key held down to choose another library."

I am able to open my iphoto library when I relaunch it holding the "option" key down, but I wasn't sure if it was being launched from my computer or from the external. I realize there are other threads regarding the matter, but unfortunately they still did not answer my question as I have no idea what the message means. All I want is a definitive answer as to whether the iphoto library is now backed up on my external. Thanks in advance for your help and patience!
