Ok, thanks for all the answers, so if i change the settings to Auto Write Changes to XMP will it change exisiting files? If i do this, i should copy the original file and XMP File over to the second backup after finishing editing? But i still need to save the catalog file to the second backup too? Also i need to change where the original backup is sent to a different location out of the catalog folder. Just clarifying also that the catalog file is where all the edit information is kept? Lastly what happens when you have to use the second backup? how do you reload your photos into Lightroom so all the edits are kept? I'm nearly there, thanks for all the patience and advice so far.
