I am really struggling with finding a way to back up and store my photos, particularly using an external HD. I want to be able to put photos on an external hard drive and then delete them off my MacBook. It is my understanding that Time Machine will not accomplish this. Is there a way to export photos that includes all the metadata? I feel like having photos exported with no date stamp is relatively useless. Is there any kind of app that would let me do this? In the past I've used iPhoto library manager and created iPhoto libraries on the hard drive, but now I am running into so many problems with the transition to photos - I can't open the libraries, I can't continue to use the app (now "power photos") to create libraries on the HD because the HD isn't formatted in extended OS; I can't reformat it without erasing what is on there. It is such a flipping headache. Also, if I "optimize storage" on my MacBook and iPhone, so that the full photos are only stored in the cloud... does anyone know if my auto upload to google photos from my iPhone will still upload the full resolution photos? I'm not sure how or if it will all integrate together... but I'm open to other options. Please, if someone has a better way or wishes to share their methods for storing photos, I am all ears. My MacBook air does not have a lot of space, so I do not want to keep them all on the internal HD.
