Automatic daily backups of Internet-based data?

I have a bunch of online data sources (BandCamp, YouTube) that I want to keep automatically backed up, say by daily downloading anything that I don't already have downloaded. Right now I'm just running a daily systemd service that invokes things like youtube-dl and bandcamp-collection-downloader, but I'm wondering if there exist solutions that are a little more robust.

Thanks if anyone knows.
