You never know what’s going to be pulled down from your favorite social media sites. That means, if the show is removed, you wouldn’t have any way to access it. If you’ve already downloaded that information, however, you’ll be able to pull it back up and watch it over and over again, however frequently you want. You don’t have to worry about whether it’s going to still be available on the social media site you use when you go back to it.
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.
Jihosoft 4K Video Downloader is available as a completely free system that actually works for both PC and Mac users, but there’s a paid version as well. What’s really great about this YouTube video downloader is that it actually works for just about any kind of video you want to download, whether that video comes from Facebook, Instagram, Twitter, SoundCloud, or YouTube, so you’re not stuck with just one platform. You’re also going to have the option to download in just about any resolution and still get all the audio and subtitles that usually come with the video. On top of all that, you can convert to any video format or even MP3 audio, so you’re always able to watch (or listen).
Since you're probably going to be paying for a backup service for years, cost is an important factor to consider. All the services rounded up here are subscription-based, but they partition their features and fees differently, so it's worth comparing plans closely before committing to one. Most construct pricing tiers based on the amount of cloud storage included, however, or by the number of devices you can use with an account. A few services offer permanent free accounts, but those plans impose paltry storage limits or restrict key features to the paid versions. Watch out for file-size upload limits as well.
