I'd like to keep a backup of 6+ years/~10gb of important messages off of my Android device (GrapheneOS Pixel 8 Pro) in case I ever lose it. However, when I connect to Windows laptop and try selecting the SignalBackups folder to copy and paste it gets stuck on 'Calculating the time required to copy the files' without actually transferring anything. Is there a solution to moving the backup files? I see a pretty techy, command line version of a Github program called SignalBackup Tools, but I don't really need the ability to decrypt and read messages on my laptop - this would just be an off-device backup that I could reload on my phone if I ever lose or destroy it. Having an on-device only backup seems to be fairly useless.
