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.
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.
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.
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.
The DVDVideoSoft system gives you free downloads in just about any style you might need. It’s an easier YouTube video downloader that consists of only three different steps. The system is older than some because it’s more than ten years old and it provides some of the best quality you could want. It’s available to be used on both PC and Mac computers, which gives you the level of versatility and flexibility that you’re looking for before you even get started. Plus, you can get a range of different options or different formatting features to the videos that you want to download.
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.
