It appears that Signal is currently working on end to end encrypted cloud backups for iOS and Android. It looks like there could be both free and paid plans. The free plan could provide full message text backups but only media backups from the last 30 days. The paid plan (for like, 3$/month) could provide full message text and media backups with a storage limit of 1TB. NOTE: This feature is under active development and all of these details are subject to change.
