Do you prefer keeping your messaging backups on your device rather than on a cloud server?
Signal has released version 8.30 for iOS and desktop, completing the rollout of encrypted local backups across all major platforms. This release ensures that users can now create and restore encrypted chat archives on Apple and desktop devices, similar to existing support on Android.
Why it matters
Standardizing backup architecture across all platforms improves data portability and recovery for users migrating between devices. This development mitigates the risk of permanent chat history loss without compromising end-to-end encryption principles.
Signal version 8.30 introduces tiered backup constraints, limiting free hosted backups to 45 days of media and 128 KB per message, while paid plans receive 100 GB. Unlike local backups which remain unrestricted in size, hosted backups rely on a supplemental key that rotates on a daily cycle.
The players
Signal
A privacy-focused messaging organization that develops an open-source, end-to-end encrypted communication protocol and application.
The details
The system utilizes a recovery key to ensure that only the user can decrypt the backup archive. For media-heavy migrations, the iOS client enables a direct, end-to-end encrypted Wi-Fi Aware link to facilitate data transfer between two iPhones. Disappearing messages with a lifespan of 24 hours or less are intentionally excluded from these backups to preserve their ephemeral nature.
Timeline
2025: Android support for encrypted backups was first introduced.
September 29, 2026: Signal released version 8.30 for all users.
The Tech Race
This release aligns the feature set across iOS, desktop, and Android following the initial deployment of the backup architecture on Android in 2025. It reflects a strategic push by the developers to ensure platform parity for encrypted local and hosted data management.
Users can now move chat history between iOS and desktop devices by generating an encrypted local backup. This functionality requires a recovery key, which users must save to ensure they can restore their data on new hardware.
The takeaway
Signal has achieved functional parity for chat backups across its entire client suite, removing a significant hurdle for multi-device users. Owners should verify their current application version is updated to 8.30 to access these encryption and restoration tools.
