Bitcasa starts you off with 10GB for free, but $100/yr throws the floodgates open and gets you unlimited storage for anything you want to sync, share, or back up. Plus, you can connect as many computers or devices to your account as you choose, so you don't pay by the PC. It's client isn't quite as robust as some of the other tools here, but if you're more interested in a flat fee for unlimited space and you can handle the details of which files go where and when, it's a solid option.

An online backup service's speed depends on how quickly it can encrypt, compress, and upload files to its servers. This should be of particular concern if you need to back up (or restore) a large amount of data. A high-performance backup service also minimizes its effect on network and system resources. Make sure to check out our speed test results in the review of any service you're contemplating using. Backup speed should not be the sole determinant of which online backup service you use, but fast upload speeds can certainly make initial and subsequent backups less disruptive.
Two ways to back up a channel. So one is the way that I do it is to just put all the videos on an external hard drive after I’ve uploaded them to this channel or my other channels and just double my external hard drive. And an external hard drive also backs up to an online backup account I have at backblaze.com, which I love. I’ve tried other ones and they’re absolutely my favorite. Put a link to them in the description below. If you want to use them it’s like $50 for the year for unlimited storage on the cloud. It’s awesome.
Another problem many people run into with not downloading videos is that they often forget how they got there in the first place. You might forget the title or who posted the video or even some of the key features. That makes it difficult to find the video again in the future. When it comes to downloading those videos, however, you won’t have to worry about that because you’ll have the videos you like to watch available right there. You won’t have to worry about how you’re going to track it down later on because you’ll have it in whatever folder you want with a name that means something to you.
