Ok, I have all my image files on a second external hard drive. I'm shooting for a complete double-backup system so if one external drive and/or my laptop goes down, I will be able to start it up eventually again without losing anything. Like I said, I've never used catalogs before so I have a few quick Q's.
1. Does the backup prompt when Lightroom starts update the catalog if new photos have been added and edited, or do I have to re-export the catalog in order to include new photos?
LR will create a new catalog each back up so will be up to date with files at the time of the back up.
2. What does "test the integrity of this catalog" mean?
LR is checking the database for errors and correcting if possible, I have not had any errors with this.
3. Is there a setting in the catalog setting I need to make SURE is checked or unchecked to keep the edits when I export it?
I use the "Autowrite to XMP" which keeps the changes up to date in the files as well as the LR catalog. This is found in Catalog Settings/Metadata.
Thanks a BUNCH for your reply. This is exactly what I was looking for. I knew it was in there somewhere, I just couldn't quite put my finger on it.
