Most services encrypt your files with strong systems such as AES 256 before sending them up to the servers over an encrypted connection. The majority of products we tested also offer a private encryption key option. If you choose to manage your own encryption keys (basically the "key" that decrypts your backup), know that it is your responsibility to remember it. The online backup service itself will not be able to help you reset the password if you forget it. On the flip side, this means that no one (including employees of the backup service and law enforcement officials) other than you can unlock your backups. This is ideal from a privacy and security standpoint. Use a password manager to keep track of your private encryption key if you think you will forget it.

Backup services vary widely in how they set up and perform backups. For example, the totally hands-free Backblaze automatically encrypts and uploads all your important files without any input. On the other hand, services such as IDrive and Acronis True Image let you choose specific files you want from a file tree. Note that some services restrict you from backing up specific file types or using particular sources, such as from an external or network drive. Make sure the service you choose supports all your needs.

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. This service provides downloads for what it considers ‘educational purposes.’ It does block any kind of content that has copyrighted material in it, which means you’re not going to have quite as many options for what you want to download, but you’re still going to have a lot of interesting things that you can listen to or watch. What’s really great is that it’s simple to use.
In general, when we speak about cloud backup files are mirrored from a device to the cloud. This can be your computer, a server, your mobile or any machine that stores data locally. Using the cloud reduces the risk of total data loss because data is stored remotely. Whatever happens to your computer you can always retrieve your files because of that 'mirroring process' that took place earlier via the internet.
Bitcasa Infinite Drive is relatively new, but it's one of your favorite cloud storage providers in general, mostly because they offer virtually unlimited stroage for syncing and backups. When we say unlimited, we mean it—some of you are using terabytes of storage with Bitcasa. It's not primarily a backup service though, and while it was built for file syncing and storage, the Bitcasa desktop client does support regular file backups. Bitcasa supports Windows and OS X, and encrypts all of your files before uploading so they stay safe from prying eyes. Bitcasa even keeps revision history, so if you've backed up a file multiple times and need an older version, you can pick it out and restore it. Plus, you can use the Bitcasa mobile apps for iOS, Android, and Windows Phone to access your data on the go.
