How to Manage Large Photos Library with iCloud
I have an iMac with a 1TB drive. El Capitan.
I have a Photos Library that is 450GB.
I currently do NOT use iCloud Photo Library.
I backup Library to external drive.
I would like to move to 500GB SSD drive so I need to trim Photos Library to fit.
I have tried to read through as much info, but I still not clear on some points.
Hard to test on large library.
Going through and cleaning up a large Photo Library is time consuming so I am looking for less hands on options.
My thought:
1. Upgrade to 1TB iCloud Storage Plan
2. Turn on iCloud Photo Library (leave originals) and wait a couple of days/weeks/months for large library to sync to iCloud.
3. Turn on iCloud Photo Library (Optimized) on iPhone and iPad to sync all libraries and get all Originals to iCloud and then to iMac
Q1. How much space will a large library like this takes on an iOS device. I am concerned even an optimized library will fill up 64GB device.
(I know this is media dependent, but only looking for a guideline for iOS, I think OS X is about 9to1)
4. Once everything is synced, copy Photos Library to EHD (properly formatted) as a backup.
5. Launch Photos Library on EHD to ensure working properly.
6. Leave Photos Library on iMac as the synced library. Don't want to keep EHD always connected.
7. Change Photos library to optimized on the computer and let sync complete.
That should give me an optimized library on the iMac and a full library on the EHD.
However, since the EHD is not the Main library for iCloud sync, it will not stay updated.
Q2. Can I create another user account on the iMac with my iCloud settings and use the EHD as the main library with full originals?
That would allow me to periodically plug in the EHD, launch the other user account and let Photos sync updates and get new originals.
This would mainly be used as a backup plan so I don't rely only on iCloud itself.
Is this a reasonable plan or am I way off base.
