The number one reason to download the entire YouTube channel is that you’re going to have offline access to them. If you want to catch up on your favorite shows but you’re going to be without internet for a while you may want to have a way to do it without the internet. Being able to get access wherever you happen to be, directly on your device, is going to be an important step. It’s going to make sure that you have something to do during that time that you’re away from internet access or not wanting to use your internet access (which is another great reason).
Carbonite is online backup only, so it doesn't really work well for local backups or backups to external drives. You'll still have to handle that yourself. You can try Carbonite for free for 15 days, but after that you'll need to pay up $60/yr to back up one computer with their Home plan, $100/yr to back up one computer with their Home Plus plan, and $150/ur to back up one computer with their Home Premium plan. You can read more about Carbonite's plans and pricing here.
CrashPlan is completely free if you're just doing local backups, but even online backups are affordable, with CrashPlan+ accounts starting at $2/mo (per computer) for 10GB of online backup storage, and going up to $4/mo (per computer) for unlimited online backup storage and $9/mo for unlimited online backup storage for a whole household. You can check out their plans here, and try them free for 30 days with a new account.
With this online YouTube channel downloader, you have the ability to download the YouTube channel you want completely free, as long as it’s not copyrighted.

What’s really great is that it’s simple to use.
