+## Sync only selected photos
+
+If you have a large number of photos on the device, and you would prefer not to backup all the photos, then it might be prudent to only backup selected photos from device to the Immich server.
+
+First, you need to enable the Storage Indicator in your app's settings. Navigate to **<ins>Settings -> Photo Grid</ins>** and enable **"Show Storage indicator on asset tiles"**; this makes it easy to distinguish local-only assets and synced assets.
+:::note
+This will enable a small cloud icon on the bottom right corner of the asset tile, indicating that the asset is synced to the server:
+
+1. <Icon path={mdiCloudOffOutline} size={1} /> - Local-only asset; not synced to the server
+2. <Icon path={mdiCloudCheckOutline} size={1} /> - Asset is synced to the server :::
+
+Now make sure that the local album is selected in the backup screen (steps 1-2 above). You can find these albums listed in **<ins>Library -> On this device</ins>**. To selectively upload photos from these albums, simply select the local-only photos and tap on "Upload" button in the dynamic bottom menu.

+<img

+  width="40%"
+  title="Upload button after photos selection"
+/>

 ## Album Sync
 
 You can sync or mirror an album from your phone to the Immich server on your account. For example, if you select Recents, Camera and Videos album for backup, the corresponding album with the same name will be created on the server. Once the assets from those albums are uploaded, they will be put into the target albums automatically.

 The backup time differs depending on how many photos are on your mobile device. Large uploads may
 take quite a while.
+To quickly get going, you can selectively upload few photos first, by following this [guide](/docs/features/mobile-app#sync-only-selected-photos).
 
 You can select the **Jobs** tab to see Immich processing your photos.
