Please add some way to send it over FTP/FTPS/SFTP/SCP/WebDav/SMB/whatever so I can automatically backup to my own server that isn't on my phone. I need something fully automated or I won't often do it. This is also really important if the free space on my phone is less than the size of the Signal archive, and even more so if the Signal archive is more than 50% of the total space on my phone.
