Lightroom (cloud) Saving a copy to external hdd advice

[Ed.Brown]

Hi, there good people 👋 

I wanted to try using Lr (cloud) for some personal projects - I am a long-time user of classic but I wanted to try and use the cloud version for some personal ideas.

If I tell Lr to backup local copies to my 4TB external and then I am on my travels, will Lr download to a random place on my MacBook taking space or will it simply keep looking until I am home and then it will continue as expected?

I understand I can test this myself but I did not want to go all in and then my 1tb MacBook that has 560gb space free will grind to a halt

I hope this makes some sense and thanks in advance for your time and help

Lightroom needs to make a temporary copy when you upload new images, so I am pretty sure it will store that copy in the default location (which is inside the Library package) if you external drive is not available.
