I have unfortunately lost signal history on various devices. Most recently I lost my iOS history when I restored from a backup without following the right procedure to keep Signal history. I have the full history on my desktop macOS signal though.

Can I use this to restore my macOS signal backup to my iOS phone, so I once again have access to all my old messages on the phone?

> The technology that underpins this initial version of secure backups will also serve as the foundation for more secure backup options in the near future. Our future plans include letting you save a secure backup archive to the location of your choosing, alongside features that let you transfer your encrypted message history between Android, iOS, and Desktop devices.
