Signal, the secure messaging app, released version 8.30, completing the rollout of its secure backups feature across all supported operating systems (Android, iOS, Linux, macOS, and Windows).

The feature, introduced on Android nearly a year ago, lets users create end-to-end encrypted backups of their chats and restore them on other devices if they lose their phone.

The backup system supports two options: Signal-hosted backups, limited to 45 days of media and 128 KB per message for free users (100 GB in paid plans), and on-device, local backups, with no size restrictions.
