backup iphoto library or just pics
I have searched the forum and i believe my question is a little more simple than what I have been finding. I am currently running version 8.1.2 of iphoto and version 8.0.6 of imovie. I have two identical external hard drives that I back up my pictures and video to, the same stuff on both drives in case one crashes. I will label my events in iphoto as April pics, April video - May pics, May video and so forth. My iphoto libraries are saved by year (2013 iphoto ect.) I also have video that i have imported into imovie backed up under a imove events folder. These events show up in my imovie when the hard drive is connected. My question is:
Is this the best way to be backing up? I have thought I may need to just put all the pics into folders and back that up on the external hard drives. I am worried that if I update iphoto it will no longer open the old backed up iphoto libraries. Also, is it a good idea to have my video backed up as imove events or should i pull these out into its own folder as .mov files? I do not like the fact that I cannot look at photos on the external hard drive hard drive, I need to open iphoto to view the pics on my externalhard drive.
Thank you for your input.
