[Feature] Two-way Sync

[partnerinflight]

The feature

This has been requested in various forms, but wanted to generalize a bit. I'd love to see a way to indicate the type of sync Immich performs. Specifically:

• Default one-way sync: assets sync from Photos to Immich only.
• One-way smart sync: assets deleted from Immich aren't re-synced from cloud.
• Two-way sync: assets deleted in Photos are deleted from Immich. Assets deleted from Immich are deleted in Photos.

I would at least ask for the one-way smart sync; without that, Immich's usability as a primary photo browsing destination is limited, as I frequently find things synced to Immich I actually want to delete. If they're just going to resync again, that would be useless.

Platform

• Server
• Web
• Mobile

I think there are two main cases here. Photos that want be deleted in both server and mobile due to being discarded, and photos that want to be kept in the server but deleted in the mobile to save space in the latter. And both are required in a normal usage (we all take bad pics and have limited storage in the mobile devices).

I agree with this. My main use case is that I still want to use the default iPhone Photos app to manage my photos, so it would be great if photos deleted there are also deleted from Immich. Although this feels like maybe it shouldn't be the default behavior, and instead toggled on/off via a setting.

I think it would also be great for a cloud only option. Have files deleted locally once they're synced to Immich. Similar to how ES File Explorer works when you import photos. It prompts for the deletion of the synced files.

I'm specifically looking for two-way sync.

I sometime want to keep photos on the phone even if I delete them on Immich so that possibility must exist like now.

Hi, I add a new proposal for a new option for this sync feature.

"Free up space" option

Description: Add a "Free up space" option in the Immich mobile app that allows users to delete photos and videos from their device while retaining them in Immich storage.

Details:

• Accessibility: Include in the main menu or settings.
• Functionality: Users select items to delete from the device, keeping them in Immich cloud storage.
• Confirmation: Show a warning to confirm the action, clarifying that items will only be removed from the device.
• Notifications: Inform users when items are successfully deleted from the device.

Benefits:

• Space optimization: Frees up device storage.
• Data security: Ensures items remain safe in Immich.
• Ease of use: Simplifies storage management on mobile devices.

I think we can add at this scope adding and modifying.

Two way sync : add in the cloud if photo is added in album from mobile and download in the mobile if photo is added from web or another phone
One way sync (mobile -> cloud): add in the cloud if photo is added in album from mobile
One way sync (sync -> mobile): add in the mobile all the new photo that are added in the cloud

The photo is download in the mobile in the same folder that the album concerned
