How can this be?

I'm trying to backup and restore a 64 GB iPad Pro (2017) to a 32 GB iPad Pro (2016). I removed enough data from the 2017 iPad to make it use only 26 GB of the 64 GB. But when I try to restore it to the 32 GB iPad it doesn't work complaining that there is not enough space on the iPad. How is this possible?

Btw I should also say that the content of the 64 GB iPad Pro is itself the restored backup from an older iPad Air 2 which had about 46 GB on it. But for some reason I still don't understand that shrank to 26 GB when transferred to the 64 GB 2017 iPad Pro. What's going on here?

Could it be (just wildly guessing) that the 20 GB of missing data from the iPad Air 2 are hiding somewhere on the 64 GB 2017 iPad Pro, as well as its iTunes backup, and that is why the backup can't be transferred to the 32 GB iPad Pro?

Remember that your 64 GB iPad only has about 55GB of useable space and the 32GB probably only had around 26-28 GB of usable space. You need to decrease the size of the backup to around 20 GB.

Thanks. Most of my storage is photos, which are also backed up in iCloud. Do you know how I can reduce the number or size of locally stored photos?

If your iCloud Photo Library is turned OFF you can import the photos to your computer or you could AirDrop them to another device that has enough storage.
