so, I have lightroom set up to backup on exit. This will back up to my EHD. Since I am a complete non computer type I get kind of lost from this point. On my EHD there is a folder called backups and when I look at that folder there is a long list of all the backups - date & time. First - can I delete the olderbackups? Secondly - the photos that get imported from my camera card to lightroom - as I understand the actual photos are not in lightroom. Where are they? How can I also copy them( the raw files) to a second EHD to ensure a backup of those in case EHD #1 were to fail? Can I simply copy a folder that contains the photos that have been imported? What folder? Thanks
