Not OP. While I've personally not yet fully migrated out of Google, I found Synching and Resilio Sync quite useful to transparently backup photos to my own computer. And to prevent losses, I have a Backblaze subscription.

While I do have a VPS, it only has like 20GB, so I've yet to find an affordable and easy photo sharing solution.

You can set up PhotoStructure to build smaller (4k, 1080p, whatever you want) previews on your home server, and rsync just the previews dir and DB periodically up to your VPS. A couple of my beta users do this. (I'm the author, btw).

Hey thanks, I'll take a look!

As always in this threads I hear people talking about SyncThing etc (and i have it and it's neat) but that works for Android. How do you exit the iCloud land in an easy and reliable way? There is no SyncThing for iOS.

I wish SyncThing was more userfriendly or something. I've tried it on different Android phones and computers and have never gotten it to work.

I use Wasabi with Clouberry for backups and otherwise store all data on my hard disks.

But if you're into "cloud" storage, Mega.nz gives you 50GB of free and very reliable storage.

I have a NAS that backs up to rsync.net.
