The system offers two options: Signal-hosted backups (limited for free users, up to 100 GB on paid plans) and unrestricted on-device local backups, both encrypted and requiring a recovery key. The update also unifies Android's backup format with the new cross-platform format, deduplicates media storage, lets paying users purge local media while retrieving it from hosted backups, and adds direct iPhone-to-iPhone transfer via an encrypted Wi-Fi Aware link. Signal says this closes phase one of its backups project. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does Signal 8.30 support local encrypted backups on iOS and desktop? Yes, Signal version 8.30 brings on-device encrypted backup support to iOS and desktop, completing the feature's rollout across Android, iOS, Linux, macOS, and Windows. Local backups have no size restrictions, unlike Signal-hosted backups which cap free users at 45 days of media and 128 KB per message. _Track messaging app updates like Signal's backup rollout as new releases land on daily.dev._ ### What is the difference between Signal's hosted backups and on-device backups? Hosted backups are limited to 45 days of media and 128 KB per message for free users, or 100 GB on paid plans, and use a supplemental key rotating daily in a Trusted Execution Environment for forward secrecy. On-device local backups have no size limits, and a single recovery key can decrypt all past backups regardless of storage location. _Compare encrypted backup tradeoffs across messaging apps on daily.dev before choosing a storage strategy._ ### Why are Signal backup recovery keys a security concern? Threat actors, including Russian state-linked hackers reported by the FBI, have targeted Signal backup recovery keys because a single on-device recovery key can decrypt all past backup files encrypted with it, regardless of where those files are stored, making key theft highly valuable to attackers. _Follow emerging threats against encrypted messaging keys on daily.dev to keep defenses current._ ## Similar posts on daily.dev - [Signal’s secure message backups arrive on iOS](https://daily.dev/posts/signal-s-secure-message-backups-arrive-on-ios-mxbbrpbio) · The Verge · 0 upvotes · 0 comments - [WhatsApp Rolls Out Passkey-Secured Backups On Android, iOS](https://daily.dev/posts/whatsapp-rolls-out-passkey-secured-backups-on-android-ios-uepmtl19f) · Latest Hacking News · 4 upvotes · 0 comments - [Hackers are trying to steal Signal users’ backups in new wave of phishing attacks](https://daily.dev/posts/hackers-are-trying-to-steal-signal-users-backups-in-new-wave-of-phishing-attacks-wqsdhziyz) · TechCrunch · 0 upvotes · 0 comments - [Labyrinth 1.1: Making End-to-End Encrypted Backups Even More Reliable](https://daily.dev/posts/labyrinth-1-1-making-end-to-end-encrypted-backups-even-more-reliable-k2szprini) · Facebook Engineering · 0 upvotes · 0 comments - [WhatsApp can now use passkeys to secure your backups](https://daily.dev/posts/whatsapp-can-now-use-passkeys-to-secure-your-backups-c7hexsal8) · The Verge · 1 upvotes · 0 comments --- Tags: [#ios](https://daily.dev/tags/ios), [#privacy](https://daily.dev/tags/privacy), [#encryption](https://daily.dev/tags/encryption) [View this post on daily.dev](https://daily.dev/posts/signal-adds-encypted-local-backup-support-to-ios-desktop-apps-ln1xgkwsg) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Signal adds encypted local backup support to iOS, desktop apps","url":"https://daily.dev/posts/signal-adds-encypted-local-backup-support-to-ios-desktop-apps-ln1xgkwsg","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/signal-adds-encypted-local-backup-support-to-ios-desktop-apps-ln1xgkwsg"},"datePublished":"2026-09-29T21:34:02.922Z","dateModified":"2026-09-29T21:54:38.349Z","description":"Signal version 8.30 completes the rollout of encrypted backup support to iOS and desktop, following its earlier arrival on Android.
