Backups & Lightroom

Hi POTN - Just after a little advice from any one who uses Lightroom.

Currently I store all my exposures on my laptop, and have a backup stored on a external drive. I backed up everything by right clicking the top, root folder in Lightroom and selecting "export this folder as a catalog".

While this backs everything up fine, when I've added more exposures to my latop for review, editing etc I can't really do a incremental backup of the catlog, It doesn't let me save over the catalog file on my external. I have to delete everything, and re-do it all.

I knwo there must be an easier way, mabe just backing up the catalog (and not the actual exposures?) and just copying the new exposures across to my external drive when they need updating.

I don't even know if I'm explaining this properly

Help is much aprreciated

Buy a backup program. I use Acronis True Image. I backup my catalog and my images using two separate tasks. Much easier to do properly.

Simple, have it check your catalog every day and backup to the backup drive, and when you import, use the backup import feature and set it to your drive. This means that everything is backed up regularly, though you also lose the ability to have external xmp because those can't be backed up normally.
