Think you’re in the wrong sub for this as recording is done on the application layer of each device unless we are talking about self hosted PBX systems that enforce recording. You looking for an Android or iOS app to do this on your mobile providers phone number or something else?

If you look at my recent post history I gave out my script using rclone to backup my server. It’s in NixOS but you can ignore it as it is bash scripting at its core. It has everything you need like using rclone to delete older backups.

I doubt your using NixOS so this config might seem useless but at its core it is a simple systemd timer service and bash scripting.

To convert this to another OS you will use cron to call the script at the time you want. Copy the part between script=“” and then change out variables like the location of where docker-compose is stored since its different on NixOS.

Let me explain the script. We start out by defining the backupDate variable, this will be the name of the zip file. As of now that variable would be 2023-07-12. We then go to each folder with a docker-compose.yml file and take it down. You could also replace down with stop if you don’t plan on updating each night like I do. I use rclone to connect to Dropbox but rclone supports many providers so check it out and see if it has the one you need. Lastly I use rclone to connect to my Dropbox and delete anything older than 7 days in the backup folder. If you end up going my route and get stuck let me know and I can help out. Good luck.
