This was something I didn’t fully appreciate until I started working on an iPhone photo backup app.
If Optimize iPhone Storage is enabled, you can scroll through years of photos in Apple Photos while some (if not All) of the full originals exist only in iCloud.
That becomes important when you decide:
“I want to plug in a USB drive and make my own offline copy.”
So I recently updated VaultDrive to handle this workflow directly.
Connect a compatible USB drive or SSD to your iPhone, select what you want to back up, and VaultDrive can:
✅ Copy photos/videos already stored locally on iPhone directly to USB
✅ Detect originals that need to be downloaded from iCloud
✅ Download those originals and then copy them to USB
✅ Let you choose Wi-Fi only or Wi-Fi + Cellular for iCloud downloads
✅ Preserve the original photo/video files and embedded metadata
✅ Keep useful source/folder organization instead of creating artificial date-based folders
✅ Resume backups while skipping files that were already copied
And you still don't need a Mac or PC.
For photos already stored locally on the iPhone, the transfer is directly from the phone to your USB drive—there's no VaultDrive cloud upload in between.
For iCloud-only originals, Apple obviously still needs an internet connection to download them first.
That distinction matters to me because the point of VaultDrive isn't to tell people to abandon iCloud.
It's to give you another option:
Keep Apple Photos/iCloud for convenience, but also have a physical copy of important memories on storage you control.
I built this because I wanted that workflow to be as simple as:
iPhone → USB drive → my Offline copy.
If anyone here has a large Apple Photos library, I'd be interested to know how much of it is actually stored locally versus optimized into iCloud.
