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 keep us covered when our primary drive finally croaks.

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 great third-party backup options have cropped up in recent years to help solve the woes of Windows users.

Why you should trust us: It’s in our name: PCWorld. Our reviewers have been testing PC hardware, software, and services for decades. Our backup evaluations are thorough and rigorous, testing the promises and limitations of every product — from performance to the practicalities of regular use. As PC users ourselves, we know what makes a product stand out. Only the best online backup services make this list. For more about our testing process, scroll to the bottom of this article.

Alternatively, if you’d prefer to keep your data on the cloud or need the flexibility of data storage for different operating systems, then check out our list of best online backup services.

Updated July 3, 2024: See our recent review of NTI Backup Pro 7. It offers the full array of backup functions, such as file/folder, image, continuous, and cloud backup, making it a very tempting option, if not for the pricey cloud storage and some annoying glitches.

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.
