I recently installed 2 internal hard drives to use as backup drives on my PC. When I go to where LR2 keeps its catalog and backup files, I see several files (Backups, Lightroom 2 Catalog Preview.lrdata, Lightroom 2 Catalog, Lightroom 2 catalog.lrcat.lock, Lightroom Catalog, Lightroom 2 catalog.lrcat-journal). Do I copy-paste all these files to the backup drives? Is there a simpler way to do it from LR2?
