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.
Backblaze earned praise from many of you for being easy to set up, even for non-technical people. It's built for people who want to get their data backed up, without being forced to search for error codes and cryptic status messages whenever something goes wrong. To that point, Backblaze backs up just about everything on your system. You get some control over what's backed up and what isn't, but the point is to be fast, easy, and hands-off, so everything on your system—documents, music, video, external drives you have plugged in, just about anything. Instead of telling what they do back up, Backblaze actually has a special page dedicated to what they don't back up instead. Backblaze offers unlimited storage for your backed up data, and while by default it only backs up files smaller than 4GB, you can bump that up if you need to. Like other online backup services, it runs in the background, backing up your data all the time (or when you schedule it to, if you prefer), and your data is encrypted so only you have access to it. It supports Windows and OS X, and is smart enough to de-dupe data, do incremental backups, and keep backup processes low on system resources. You can read more about Backblaze's features here.
The iDrive service comes with backup clients for nearly every PC and device, including Windows Phone—a rarity these days. The company provides additional storage for syncing all your devices and PCs, allows sharing of files with anyone, and has the ability to back up to a local drive. The company also has several affordable pay plans. For all the details, read our full review of iDrive. 
It's been a long time since we last looked at online backup tools, so we figured it was time to take another look. Earlier this week we asked you which online backup services were the best: The ones that offered the most seamless and simple backups, fast and complete restores, easy-to-use backup clients, and of course, storage for your money. You responded with a number of options, but we only have room for your top five. Here they are, in no particular order:

Here at BestBackups, we put together all of our Top Backups lists with the aim of introducing our readers to the best online storage and backup solutions available. However, due to the varying needs of consumers with video files, the best services to backup videos roundup was made taking a slightly different approach to our standard 1-5 ranking. Instead, we focused on a few key features that we believed ticked all the most important boxes and drew attention to the services that do them best.

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.

Among the free programs we tested, Aomei Backupper Standard wins primarily because it has the most features, including imaging, file backup, disk cloning, and plain file syncing, plus multiple scheduling options (see our full review). Sure, its bitmapped interface may be retro, but the layout and workflow are intuitive. And though it’s on the slower side for backing up sets of files, it’s the fastest software we’ve tested so far for backing up full disks and partitions. Its CPU usage during backup is also commendably light.
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.
Many users don’t welcome the new rules. For one, it means that they aren’t able to. It’s one reason that many users are looking to download their YouTube videos to their hard drive now before YouTube actually decides to block accounts. Many YouTubers are also looking to make their videos private, since any hint of blood and gore could have their videos taken down – and they don’t want that.
In addition to the 5 GB free option, OpenDrive has one consumer-grade plan called Personal Unlimited. It costs $9.95 /month and offers an unlimited amount of storage space for your backed up files. Prepay for one year at $99 to bring that down to $8.25 /month. You can add an additional computer for $9.95 extra /computer, up to three extras for a total of four.
An online backup service isn't much use if it doesn't make the process of restoring or recovering your data quick and simple. For example, a service should offer search tools for finding particular files in your backup. It's also desirable for a service to be able to replicate an entire folder-tree structure so that it can help you recover from bigger data losses. Keep in mind that if you buy a plan that covers just one computer, you may have to transfer the account to a new PC if you ever switch your main device or if you need to restore data from a damaged computer to a replacement.
