Best Cloud Backups For Mac Windows Unlimited Data

Posted By admin On 15.02.22

(But if you lose your private key, the cloud-backup service can't recover your data.) Otherwise, cloud-backup services can vary greatly. An online backup service (sometimes called “cloud backup”), which copies your data over the Internet to the service’s servers, offers the security of off-site storage for your most essential files, along with a simple, one-time setup procedure.

Secure Your Data With Online Backup Software

You can either tear out your hair when a disaster strikes your hard drive or you can prepare for it ahead of time, but data loss is as inevitable as death and taxes. An online backup service is one of the best ways to protect yourself against such threats as a crashed hard drive or accidental deletion. Natural disasters such as fires, floods, and earthquakes can also spell the end of your digital media and documents. Even if you're among the very few who diligently perform local backups at regular intervals, you could still lose data if you don't store backups offsite.

Online backup services scan your hard drive for files worthy of protecting, encrypt them for security, and send them up to the company's online servers. Once your files are uploaded, you can access and restore your data from anywhere. Though there's some overlap, online backup services shouldn't be confused with cloud storage and file syncing services like Box, Dropbox, Google Drive, OneDrive, and SugarSync. Those services do store files in the cloud, but they aren't designed to automatically protect all important documents and media files, let alone system files. Their strategy is generally to sync just one folder with all its subfolders to the cloud, and in some cases, to offer online collaborative document editing. Many backup services offer folder-syncing capabilities, but few syncing services offer full-scale backup functionality.

That being the case, we believe that an online backup service is ideal for protecting your files, this solution will not appeal to everyone. Read our guide on how to choose the best backup plan for more specific advice on how to implement a backup method that works for your needs.

How Much Does Online Backup Cost?

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.

These plans typically cover many more devices and include better administration features, but at an increased cost.

Create a Backup Set and Schedule Uploads

Best Cloud Computer Backup

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.

There are a few common practices for configuring when backups occur. The most common option is on a fixed schedule, such as once a day, week, or month. The second, which we prefer, is to upload file changes whenever they're changed and saved, otherwise known as a continuous backup setting. Services only transfer the modified part of the file in this scenario, so as not to overburden your internet connection or take up unnecessary storage. A third way is simply to upload files manually. Some may appreciate this degree of control, but this method is only effective if you remember to regularly run the backup.

How Secure Are Online Backup Services?

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.

Restoring Folders and Files

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.

Many services also offer a feature called versioning. This saves incremental changes you make to files as recoverable snapshots of the file. It's useful in case you need to get back information from an earlier version or if your latest file save becomes corrupted. Services vary widely in how many versions they keep and how long they're saved. Best-in-class services, such as SOS Online Backup and SpiderOak ONE keep an unlimited number of file versions forever.

Web and Mobile Backup Apps

One of the biggest advantages of using an online backup service is that it lets you access your files from anywhere. Most online backup providers let you view and download files from a web browser, but that should be the bare minimum. Many also include file-sharing options, the best of which even let you specify a password for access and an expiration date for the shared item.

Mac Windows 10

All the online backup services we tested offer Android and iOS apps, but the quality and utility of those apps vary widely. Some just offer simple document and media file downloads from your existing backups, but the most feature-complete allow you to back up the data on your mobile devices.

Backup Performance

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.

Disaster Recovery and Bulk Data

Some services go above and beyond, including extra capabilities that improve the experience. For example, a few offer disk courier services for bulk uploads and restores via an external drive that the company ships and manages. A couple of these services throw in a local backup component, too. If you go that route, you should take a look at our roundup of best external hard drives. Some of these services can even track your device's location and let you remotely wipe it in case it's lost or stolen.
