Backing up photos onto external hard drive

Hi all! I'm trying to set up a system for backing up my photos. I have two external hard drives. One I use for time machine and back up my entire computer. I'd like to back up ONLY the photos onto the other hard drive. And I'd like it to happen automatically whenever I add photos to the photo folder on my iMac. Is this even possible? And if not, is it possible to set up Time machine to do a different back up than what I have set up in case my computer fails? i.e., I want to keep my back ups in case of a failure. But I'd like to also have JUST photos backed up to my second external hard drive. Clear as mud?


Thanks!


PS I'm running 10.15.6 on my 2017 27" iMac. Thanks!


PPS I don't currently use the Mac Photos software, but I'm open to it if it helps me with this process.

Transfer this:

  1. Go Here: Move your Photos Library to Save Space on your Mac
  2. Scroll to: Move your Photos library to an external storage device
  3. Proceed from there as necessary

Since you are not using the Photos app, where are your photos? I don't use Photos either - mine are in a folder named (what else?) Photos and it is in my Documents folder. There are also many subfolders within that folder. In any case, not using Photos liberates you from the Apple/Photos/Library/filing system; just having a folder allows you to simply drag + drop for a backup. There are two ways: one is to use something like CarbonCopyCloner (which makes bootable clones) and just exclude everything but Photos and can be set up with any schedule, or - the method I use because I don't have that many changes to that folder - i simply throw out/empty trash the entire folder on the external and then drag 'n drop the updated folder from the internal drive. There may be other methods, but these two are the simplest to keep up with.


If you use the method mentioned to move a Photos library, you will no longer have the photos on your internal - instead of backing up, you just moved them. And you have to pay attention to any updates or moves so they don't suddenly disappear.

Thanks! This seems like the easiest, simplest method. I also just have a folder called "Pictures" in my documents folder... again, like you, filled with further folders for organization. I'll research CarbonCopyCloner. But really... just putting myself in the habit of deleting what's on my back up and replacing it periodically does make sense.
