9 best online backup services

Our PC storage drives won’t last forever and that’s why it’s always a good idea to use backup software to keep your data safe. The best Windows backup software can cover our butts when our primary drive finally up and dies.

Introduction

While Apple’s Time Machine provides users with an effective, set-it-and-forget-it recovery system, Microsoft users aren’t so lucky. Instead, users are stuck deciding the best way to keep their data safe with a patchwork system of restore points, recovery discs, and file backups. Thankfully, a number of excellent third-party backup options have cropped up in recent years to help solve the woes of Windows users.

Below you’ll find a list of our favorites, which come with easy-to-use and attractive designs as well as a full range of file and image backup capabilities. We’ve even included a couple free options that are more than worthwhile. Scroll to the bottom of this article for more info about what to look for in a Windows backup program.

R-Drive Image 7 – Best Windows backup overall

Pros
– Super-reliable, fast disk and partition imaging
– File and folder backup
– Partition manager
– Lean-and-mean Linux and WinPE boot media
– Supports Microsoft’s nearly ubiquitous VHD format

Cons
– Would like to see multiple destinations per job

Price When Reviewed: $44.95

Best Prices Today: R-Drive Image has always been a favorite of ours—a low-resource-consuming product that was ultra-reliable in creating backup images of partitions and disks. But it didn’t have as much polish as Acronis’s backup program (below) and wasn’t as feature-rich. That has changed with this latest version, which now has a more modern, user-friendly interface and more versatility in the types of backups you can perform. The latest 7.1 version adds WinPE boot-disc support and VHD compatibility to an already impressive arsenal of features. VHD compatibility, in particular, is a great new feature as R-Drive no longer entirely relies on its own proprietary images, but now allows users the option to keep backups in VHD (Virtual Hard Disk) format—which addresses one of the only previous complaints we had about the service.

Retrospect Solo – Best for added ransomware protection

Pros
– Easy to use (once learned)
– Copious feature set
– Good performance
– New anti-ransomware backup protection

Cons
– Somewhat steep learning curve

Price When Reviewed: $49

Best Prices Today: The latest version (18.5) of this stalwart Windows backup program is every bit as feature-packed as we’d expect. It even adds an interesting pre-backup file scanning to root out anomalies before overwriting your previous backup—a nod to the emergence of ransomware as a concern. It’s got a bit of a learning curve, but once familiar, Retrospect Solo delivers the goods. Read our full Retrospect Solo review

Perfect Backup – Best free Windows backup

Pros
– Familiar and easy interface
– Friendlier data selection than Windows File History
– Backs up to local media, network locations, and online services
– Logging, notifications, FTP support, and lots of other options

Cons
– No image backups
– Must be loaded for scheduled backups

Price When Reviewed: Free

Best Prices Today: Perfect Backup provides you with excellent backup options at no cost, and there’s no better price than free. Perfect Backup is both more stable and easier to use than many of the premium options for Window’s backup software. It lacks image backups for disaster recovery, which is admittedly disappointing, but also to be expected in a free service. Fortunately, it allows just about every other type of backup you’d need, such as backing up to local media, the company’s online service, and other network locations. Most users looking for an easy and free way to securely store their important data need look no further. Read our full Perfect Backup review

Windows File History backup – Best free Windows backup runner-up

Pros
– Excellent continuous data protection with versioning
– Easy, timeline browsing of backed-up files
– Integrated into Windows
– Backs up user-created libraries

Cons
– Easy “Add folder” function removed from Windows 11

Price When Reviewed: Free with Windows

Best Prices Today: Among the free programs we tested, Windows File History backup is one of the easiest continuous data protection software for Windows. It’s unfortunate that the latest version removed the “add folder” function from File History, but otherwise it continues to improve upon an already solid backup program. Also, it provides many of the features and functions of other third-party paid backup programs, all for free. And you can’t argue with free. It would’ve taken the top spot for free options if not for the fact that Perfect Backup has easier-to-use data selection tools. Read our full Windows File History backup review

How we test

We run each program through the various types of backups it’s capable of. This is largely to test reliability and hardware compatibility, but we time two: an approximately 115GB system image (two partitions), and a roughly 50GB image created from a set of smaller files and folders. We then mount the images and test their integrity via the program’s restore functions. We also test the USB boot drives created by the programs.

How to pick a backup software

As with most things—don’t over-buy. Features you don’t need add complexity and may slow down your system. Additionally, if you intend to back up to a newly purchased external hard drive, check out the software that ships with it. Seagate, WD, and others provide backup utilities that are adequate for the average user.

File backup: If you want to back up only your data (operating systems and programs can be reinstalled, though it’s mildly time- and effort-consuming), a program that backs up just the files you select is a major time-saver. Some programs automatically select the appropriate files if you use the Windows library folders (Documents, Photos, Videos, etc.).

Image backup/imaging: Images are byte-for-byte snapshots of your entire hard drive (normally without the empty sectors) or partition, and can be used to restore both the operating system and data. Imaging is the most convenient to restore in case of a system crash, and also ensures you don’t miss anything important.

Boot media: Should your system crash completely, you need an alternate way to boot and run the recovery software. Any backup program should be able to create a bootable optical disc or USB thumb drive. Some will also create a restore partition on your hard drive, which can be used instead if the hard drive is still operational.

Scheduling: If you’re going to back up effectively, you need to do it on a regular basis. Any backup program worth its salt allows you to schedule backups.

Versioning: If you’re overwriting previous files, that’s not backup, it’s one-way syncing or mirroring. Any backup program you use should allow you to retain several previous backups, or with file backup, previous versions of the file. The better software will retain and cull older backups according to criteria you establish.

Optical support: Every backup program supports hard drives, but as obsolete as they may seem, DVDs and Blu-Ray discs are great archive media. If you’re worried about optical media’s reliability, M-Disc claims its discs are reliable for a thousand years, claims that are backed up by Department of Defense testing.

Online support: An offsite copy of your data is a hedge against physical disasters such as flood, fire, and power surges. Online storage services are a great way to maintain an offsite copy of your data. Backup to Dropbox and the like is a nice feature to have.

FTP and SMB/AFP: Backing up to other computers or NAS boxes on your network or in remote locations (say, your parent’s house) is another way of physically safeguarding your data with an offsite, or at least physically discrete copy. FTP can be used for offsite, while SMB (Windows and most OS’s) and AFP (Apple) are good for other PCs or NAS on your local network.

Real time: Real-time backup means that files are backed up whenever they change, usually upon creation or save. It’s also called mirroring and is handy for keeping an immediately available copy of rapidly changing data sets. For less volatile data sets, the payoff doesn’t compensate for the drain on system resources. Instead, scheduling should be used.

Continuous backup: In this case, ‘continuous’ simply means backing up on a tight schedule, generally every 5 to 15 minutes, instead of every day or weekly. Use continuous backup for rapidly changing data sets where transfer rates are too slow, or computing power is too precious for real-time backup.

Performance: Most backups proceed in the background or during dead time, so performance isn’t a huge issue in the consumer space. However, if you’re backing up multiple machines or to multiple destinations, or dealing with very large data sets, speed is a consideration.
