Do you only need to back up the images on the external SSD volume without editing or sharing the photos? If so, then there should be no need to bring them into the Photos app. Do a direct copy from camera card to external volume, completely bypassing the iPad internal storage, so that you don’t use any of the iPad internal storage, and so nothing gets uploaded to the cloud. Below is how I do it.
The iPad has only one USB-C* port, so to connect both the camera card and the external volume to the iPad at the same time:
- Plug a USB-C hub into the USB-C port on the iPad.
- Plug the card reader into the hub (or card, if the hub has a built-in reader). If any photo apps open when you plug in the camera card, cancel out and close the apps.
- Plug the external volume into the hub.
When that’s done, both the camera card and the external SSD should be listed in the sidebar in a Files app window, letting you know they are mounted. Then you can copy files directly from card to SSD much like you would on a computer desktop, using these steps:
- On the iPad, open two windows for the Files app and set them up side by side, using Split View (a standard view in iPad OS).
- In one Files window, look for the name of the camera card in the sidebar on the left, select it, and in it, select the folder(s) where the photos/videos are stored. (The figure below doesn’t show the sidebar, it shows the path menu that drops down when you tap the circled button. The sidebar expands when you tap the first blue icon in the toolbar across the top.)
- In the other Files window, look for the name of the external SSD in the sidebar, select it, and open the folder where you want to back up the photos.
- In the Files window for the camera card, select what you want to copy (files or folders), and do one of the following:
- Tap and hold the selection until the context menu appears, and tap Copy, then tap and hold in the Files window for the folder on the SSD until the context menu appears, and tap Paste. This copies and pastes the selection to the destination folder.
- Or, drag the selection from the card reader window, and drop it in the SSD folder window,
When that finishes copying, you should have a manual backup of camera card photos on an external SSD, that does not use any space on the iPad itself. If you want to review the photos on the SSD, you can browse photos in the Files app itself by tapping a photo. No need to open any photo apps. (The Files app might not browse photos if the camera’s raw format is not yet supported by iPad OS.)
It might take some practice, but you’ll get it.
*If you have an older iPad with a Lightning port, this procedure is still possible but more challenging, partly because you will also have to supply enough power to the hub, and that part is trickier than it might seem at first.
