I’ve been to many of your seminars but still don’t know when you and Matt and many others say, backing up your catalog is not backing up photos. I’m proficient in LR editing. I do a back up once a week of catalog, but what about the photos, could you please share with me …how do I do that? No one ever explains that.. Matt, Tim Grey, no one.I’m very nervous with 86K+ photos! Thanks for your help. Was at the 20th anniversary of PS SF and you played great music!Cheers,and many thanks and well wishes for a great 2019! Barbara

1. The default location is in the same folder where your catalog resides. Yes, you can change it, but a lot of people don’t.

2. Time Machine is fine, but by running Lightroom’s backups you get the benefit of the integrity check that can catch a small problem before it becomes a big problem. Having Time Machine continue to backup a series of catalogs with problems will make it harder to recover should that problem get worse. Lightroom’s catalog backup is automated, free, and can save your bacon. I use it on my Mac and Windows machines.

I rely on my Time Machine backup as well. I also use Backblaze for online backups. I don’t see a need to clutter up the drive with Lightroom backups, too.
