Nothing has quietly fixed one of the most annoying aspects of Essential Space. The company has enabled cloud backup for content stored in the feature, meaning it is no longer tied to a single device. 

It will now travel with you, should you choose to switch from one Nothing or CMF device to another, synced via your Nothing account. 

What exactly is backed up?

Everything you’ve ever captured with the Essential Key is eligible for backup. This includes your audio recording, quick screenshots, saved images, email or document summaries — essentially the entire Essential Space content library. The feature also takes care of offline captures.

If auto-updates for apps are enabled in the Google Play Store, the app should receive the new feature automatically. However, if it doesn’t, you can update the app manually to enable cloud backup. 

Once the update is installed, you can head to Essential Space > Profile > Storage, and select Backup to set it up. The feature’s backend is based on Google’s cloud infrastructure (not Google Drive); it doesn’t count toward your personal Google storage quota.

Furthermore, the data remains fully GDPR-compliant, implying that only you can access the content.

Which devices support the feature?

For now, cloud backup for Essential Space is rolling out to all 2025-2026 Nothing and CMF phones that feature the Essential Key. To my recollection, this includes the Nothing Phone (3), Phone (4a), Phone (4a) Pro, and the CMF Phone 2 Pro, among others. 

Older devices without the Essential Key are not supported, at least for now. A gap worth flagging is that there’s no web or desktop version of Essential Space, a fact the company has already acknowledged. 

For Nothing to create a functional ecosystem of devices, the Essential Space cloud backup is quite essential. Without it, every upgrade or device reset was a potential data loss event, but the cloud backup suggests that Nothing is on the right track.
