Compare Photos in Google Photos and iCloud

All old iCloud photos were imported into Google Photos.

tl;dr

• In the end I simply downloaded all iCloud photos, and imported them into GooglePhotos (not original resolution)
• iCloud Originals were imported into /archive/media/photo/mom/iCloudPhotos-2019-08-24

Comparing iCloud and GooglePhots Downloads, to hopefully consiladte them both, with no loss and no duplicates

Notes

• Almost all files are different!

{ path: 'gPhoto.json', sz: { count: 1153, size: '1862.21MB' } }
{ path: 'iCloud.json', sz: { count: 1058, size: '2842.23MB' } }
// inverted by hash
{ invertedA: 1153, invertedB: 1056, union: 2202 }
// inverted by stamp
{ invertedA: 938, invertedB: 880, union: 938 }

example: JPEG Quality 92 n iCloud, 68 on GooglePhotos, with filsize 1611250 -> 610205

ls -l ./gPhoto/2019/IMG_1256.JPG ./iCloud/IMG_1256.JPG
jhead ./gPhoto/2019/IMG_1256.JPG ./iCloud/IMG_1256.JPG

Usage

1. first hash, produces gPhoto.json and iCloud.json
2. second compare

time node js/hash gPhoto
time node js/hash iCloud

time node js/compare gPhoto.json iCloud.json

Previous bash start

./count.sh
./sha1sum.sh
