What backup utilities come with Windows?

Sadly, while other operating systems make backup easy, Microsoft saddles users with a patchwork system of utilities and holdover imaging tools from Windows 7.

Some of these work well (Restore Points, File History), others don’t (System Repair Disc, Recovery Drive). None are suitable for quick and easy disaster recovery — even the online backup that is available when you use Windows with a Microsoft cloud account.

Thankfully, there are a number of highly capable and far more reliable third-party backup options for Windows that cover the panoply of backup, restore, migration, and disaster recovery.

Why you should trust PCWorld for backup software reviews and buying advice: 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.

Who should buy EaseUS Todo Backup 2026?

EaseUS Todo Backup 2026 (home) has matured into an outstandingly versatile and comprehensive backup solution. With a still-affordable perpetual license, it also costs less than some of the now subscription-only competition such as Acronis True Image and Macrium Reflect X.

The paid tier of EaseUS is the best all-round home-PC choice for anyone who wants comprehensive backup and recovery with a straightforward “buy once, use forever” license

EaseUS Todo Backup 2026: Further considerations

Imaging, disaster recovery, plain or compressed file/folder backup, sync, real-time (actually continuous) backup, and nearly every bell and whistle in the backup space are accounted for by Todo Backup.

In addition to its comprehensive and reliable set of features, Todo Backup greets you with a pleasingly-rendered, animated interface and a supremely logical layout.

The fact that it doesn’t force you into a subscription model is also a big plus in its favor. That said, if you want to use EaseUS’s cloud storage (third-party isn’t supported directly), you do need to opt for a yearly plan. Fortunately, it’s decently affordable: software plus 1TB of cloud storage for $60/yr.

Who should buy Acronis True Image?

True Image is a great option for anyone who wants seasoned and reliable file and image backup as well as full-fledged protection from malware (including ransomware).

True Image is for users who are amenable to a subscription-only plan, the benefits of which are the iterative and ongoing update potential as well as the inclusion of cloud storage.

Acronis True Image: Further considerations

Acronis established itself as a trustworthy stalwart in backup software years ago. In meantime the program’s moniker morphed for a while to Cyber Protect Home Office (which is actually more descriptive), but is now back again to the more recognizable True Image.

Throughout the changes, the program remained super-reliable, and gradually evolved into a versatile, flexible, backup and malware protection solution. While True Image doesn’t offer support for third-party cloud storage, only its own, the program does allow you to back up to and from network locations.

As I noted in my review, “If you’re looking for a comprehensive, set-it-and-forget-it data-safety solution, I know of nothing better — or comparable for that matter.” This does however, result in a rather heavy system footprint with multiple background processes running.

Alas, for better (the comany’s) or worse (yours), True Image is now subscription-only. I recommend bumping up from the Essentials plan to the Advanced plan, which includes 250GB of storage (with the purchase link in this article, it’s only $24.99 per year, down from $72.99).

Who should use Easeus Todo Backup Free?

Anyone who wants friendly, easy to use backup and reliable disaster recovery in one package should take a look at Easeus Todo Backup Free. The only cost to a startlingly capable suite is a couple of ads and nags.

To clarify the distinction between our paid and free picks, the free version of Easeus Todo Backup includes imaging, file/folder backup, scheduling, and boot media. Cloud storage and deeper advanced features require you to step up to the paid tier.

Easeus Todo Backup 2025: Further considerations

Easeus Todo Backup Free covers all the backup basics: File/folder backup (compressed and plain), one-way sync, system/drive/partition imaging, and all with scheduling. But there are extras you might not expect from a freebie such as backup from network locations, and what EaseUS calls real-time backup (it’s actually continuous — close enough). That’s unique for a freebie.

Todo Backup 2025 also sports the easiest, most attractive (in our estimation) interface on the market. That alone should recommend it to most users. But the fact that it just works (there are a couple of odd, non-fatal peccadilloes in the file sync), and comes with reliable disaster recovery and boot media seals the deal.

There’s a professional version that adds numerous advanced features, as well as EaseUS’s own cloud storage. See the entry above.

Arcserve ShadowProtect SPX – Best Windows backup for SMBs

Pros

  • Fast and reliable continuous data protection

Who should buy Arcserve ShadowProtect SPX?

Home, small, and other businesses who are looking for backup software more powerful than the norm, that also scales nicely in networked ecosystems will do well with this solid, feature-laden, and very fast backup program.

Besides Arcserve’s support for SMB / mixed Windows-Linux environment, it’s heavy on features that are overkill for most home users, but great for the more robust needs of business users.

Arcserve ShadowProtect SPX: Further considerations

Arcserve ShadowProtect SPX is loaded with pro- and enterprise-level features including support for third-party virtual hard drives (VHDs, etc.). It is also an excellent choice for Linux users or those in mixed Windows/Linux environments as it’s available for both operating systems.

ShadowProtect SPX is a bit pricey, but it’s extremely reliable backup software with foolproof continuous data protection. Note that the company no longer targets the average user, but I found that it works exceptionally well even on a single computer.

Other notable Windows backup software

  • Paragon Backup & Recovery Community Edition: A free program that offers robust file backup that should meet the needs of most users.
  • Perfect Backup:  Fast and competent, this free backup program is more versatile than Windows File History.
  • Aomei Backupper Pro: A complete backup solution capable of preserving your important data both locally and remotely.
  • Aomei Backupper Standard: A respectable free backup program if you can tolerate the occasional ad.
  • Retrospect 19 Solo: Includes support for both proprietary and third-party cloud storage, but sadly it lacks disaster recovery.
  • Retrospect 19 Desktop: The pro version of the above covers all the bases, but has a steep learning curve and high price.
  • Backup and Restore (Windows 7): Conveniently installed with Windows, and good for imaging but bad for disaster recover.
  • MSP360 Managed Backup: Uses a handy web-based console to provide imaging and file backup services for multiple devices at a reasonable price.
  • MSP360 Backup: The free incarnation is a worthwhile upgrade to Windows File History.
  • Iperius Backup: Has power aplenty, but the learning curve and interface might occasionally flummox less-experienced users.
  • Handy Backup 8.5 Professional: Top-notch features that might’ve garnered an Editors’ Choice award had it been entirely glitch-free and a bit easier to learn.
  • MiniTool ShadowMaker Pro 4.6: There’s a lot to like, particularly its unique ability to interface with all computers on a network.
  • Macrium Reflect Home: Would likely qualify as our favorite backup software if it wasn’t relatively pricey. It’s an exceptional program that offers everything we want from backup software — full drive/folder backup, ease of use, reliability, etc.
  • DriveImage XML: A viable free backup solution, albeit only for MBR disks.
  • Ashampoo Backup Pro 26: Overarching support for myriad backup chores with easy-to-understand wizards, but no backup from the recovery disc or option for “differential” backups.

Note that in this article we focus on local-software based solutions, although many also include a cloud component. For cloud-first backup, see our roundup of the best online backup services. Admittedly, the distinction between the two categories is blurring as they each expand their feature sets.

How we test

Our reviewers run each program through the various types of backups and restores it’s capable of — including those requiring boot media. This is largely to gauge reliability and hardware compatibility. We check speed, but such is highly reliant upon the connections and media involved.

If we notice anything is particularly fast or slow, we’ll tell you about it, but creating a functional backup is paramount.

To learn more details, see our article on how PCWorld tests backup software.

Who curated this article

Having started computing by flipping switches, Jon Jacobi has witnessed storage morph from punch cards and tape to solid state. He’s been using and testing HDDs, SATA SSDs, and NVMe SSDs for PCWorld for well over two decades. To paraphrase a well-known commercial, you might say he’s seen a thing or two.

How to choose backup software

If you recently purchased an external HDD or SSD from a major vendor such as Seagate or WD, check to see if there are backup utilities or a backup software license included. Whatever backup software you use, keep in mind the following key aspects of the best solutions: file backup for documents/photos, image backup for whole-PC rollback, boot media for dead-drive recovery, versioning for accidental overwrite protection, and know which are critical to your backup plan.

File backup

If you want to back up your essential data (operating systems and programs can be reinstalled, though it’s mildly time- and effort-consuming), a program that backs up only your important files is essential. Some programs even automatically select the appropriate files or folders. File backup can include operating system files if you wish but is still not suitable for disaster recovery.

Image backup/imaging

Images are byte-for-byte snapshots of your entire hard drive (normally not including empty sectors) or partitions, and can be used to restore the operating system, drivers, programs in one swift, fell swoop. Imaging also ensures that you don’t omit anything important as can happen with file backup.

Recovery boot media 

Should your system crash completely, you need alternate means to boot your system and restore data using your backup software. Any backup program worth its salt 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 if the issue isn’t a failed drive.

Note that we’ve run into multiple issues with Microsoft’s own Recovery Drive and System repair disc — don’t rely on those.

Scheduling

If you’re going to back up effectively, you need to do so on a regular basis. Any backup program you purchase should let you schedule backups and run them in the background. Some even will backup files as they change (real time) or at very short intervals (continuous)

Versioning

Versioning is simply retaining older version of files (or backups) rather than overwriting them during the backup/sync process. You can generally define how many versions to keep, but if you choose to cull older files, this is till not true backup which again, is an immutable copy of your data, drives, or system.

Optical discs

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, backed up by Department of Defense testing.

Online storage (cloud) support

An offsite copy of your data is a hedge against physical disasters such as theft, flood, fire, and power surges. Online storage services are a great way to meet that need. Some backup software will let you back up to Dropbox, Google Drive, OneDrive, Amazon S3 and compatible, etc. however Cloud Managers can serve as a workaround with backup programs that don’t. The downside to cloud storage is relatively slow performance. Keep a local backup for faster restores.

Network access

Backing up to other computers or NAS boxes on your network or in remote locations (say your parent’s or children’s house) is another way of safeguarding your data via a physically remote copy. If you use network storage, it can also be handy to back them up to you local system.

FTP/SFTP 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. Network support is not universal, and some backup programs allow you to back up to, but not from network shares. Just be careful in the way you expose your computers on the Internet.

Real-time backup

Real-time backup means that files are backed up whenever they change, usually upon creation or save. It’s handy for keeping an immediately available backup of rapidly changing data sets. For less volatile data sets, scheduled backups will do just fine.

Continuous backup

Continuous simply means backing up on a tight schedule, generally every few minutes, rather than in real time, daily, weekly, or monthly. Use continuous backup for rapidly changing data sets where transfer rates are too slow, or computing power too precious for real-time backup.

Performance concerns

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, backing up to multiple destinations, or dealing with very large data sets, speed will be a consideration. That said, backup speed is highly dependent upon the hardware and transport technology in use.

FAQ


1.

What is the best Windows backup software?

The best Windows backup software is Easeus Todo Backup 2025. It has everything PCWorld expects to see in a top product: A polished interface, intuitive functionality, a comprehensive approach to backing up data including imaging, file backup, sync, and disaster recovery. And most important, it’s reliable! Todo Backup also offers the option of a perpetual license or a subscription model, the latter of which can be augmented with affordable cloud storage.

2.

What is the best free Windows backup software?

It turns out that PCWorld’s favorite for-pay backup software, Easeus Todo Backup 2025, also offers a surprisingly robust free version. It matches its paid counterpart in basics such as imaging, file backup, sync, and, most especially — disaster recovery. It also features the same eminently user-friendly interface. As with most backup freeware, you will be nagged to upgrade, and Easeus’s optional cloud storage, which is surprisingly affordable, is only available at the subscription tier.

3.

Will backup software slow down my computer?

Backup software typically runs in the background or during dead time, so given even moderately modern hardware, you shouldn’t notice any decrease in performance. Most programs let you throttle the backup process if you do notice a slowdown.

4.

Does Windows Backup and Restore (Windows 7) save everything?

Yes, by default, Backup and Restore (Windows 7) saves everything on your system disk (all the partitions, including hidden ones) in what’s known as an image file that would be suitable for disaster recovery if Windows Recovery Drive and Rescue disk were reliable. News bulletin — they aren’t.

Hence, we only recommend this program for creating highly compatible VHD/VHDX images of your data drives and partitions which can be mounted as virtual drives and browsed using nothing but Windows Explorer.

5.

What’s the difference between Google Drive, Dropbox, OneDrive, etc. and backup software?

Google Drive, Dropbox, and OneDrive are what’s known as cloud storage, or online storage. They create a local virtual drive that you can drag files to, and which is eventually synced to the cloud as time allows. They also provide a Web portal where you can manage your files remotely.

However, by default these services sync changes in the data across all devices. True backups should be immutable snapshots that may be added to but not changed. Some services offer versioning (keeping older files, and adding new ones), which creates a close approximation to backup.

Cloud backup services (distinct from those mentioned above) offer many, though not all, of the benefits of Windows backup software. This is generally done with local client software that offers just basic functions like file backup and sync. You can learn more about these in our roundup of best cloud backup services.

6.

How often should backups be scheduled?

Ideally, as often as your data changes. If you are working on an important project or have work that you absolutely cannot afford to lose, you should consider real time (as data changes) or continuous (very short intervals). Hourly, daily, or longer intervals will be fine for the average user. All file backups should be augmented by weekly or monthly system backups.

7.

Can I back up files to and from my cloud storage?

Until a few years ago, most Windows backup software was restricted to making local backups — i.e., to another drive, external or internal, connected to your system. There were of course services such as Mozy that had their own backup clients, but that’s covered in our online backup roundup. Here we’re talking just plain backup programs.

The situation is improving rapidly, and many backup software vendors are adding online storage services as destinations for their backups.

If your favorite backup program doesn’t support cloud storage directly, a cloud storage manager that integrates online storage services into File Explorer can make online backup possible with just about any backup app.

8.

What’s the difference between full, differential, and incremental backup?

A full backup is a backup of all your data, regardless of how new or old it is. A differential backup is all the data that’s changed since your last full backup. An incremental backup is all the data that’s changed since any your original full and/or the last differential/incremental backup. Differential and incremental backups require a initial full backup to be restored.

Differential backups require more time to create than incremental backups, but are quicker to restore since you only need the latest iteration. Differential backups can grow to be quite large if you don’t perform full backups very often.

Incremental backups take less time to produce and are smaller, but take longer to restore as all of them created since the last full backup must be restored in the order in which they were created.

9.

What’s the difference between image backup, system backup, and file backup?

An image is low-level backup of all the sectors (including “empty” sectors if you wish) contained by a disk or partition, regardless of their pertinence to your files. It’s basically fool-proof in terms of accidentally overlooking important data.

A system backup is an disk image backup of all the partitions on your system drive. This includes several that are hidden, i.e., not enumerated as drive letters by the operating system. A system backup might also include other drives, but must contain the OS drive.

A file backup is a high-level backup of data read via the operating system’s file system. Most often this is data, but may include all the files on a drive.

10.

What should I back up?

In truth, it’s only your essential personal data that must absolutely, positively, 100% be backed up. Once the family pictures or your work-in-progress are trashed with no backup, there’s no way back other than an expensive recovery service, and even that’s not guaranteed if the physical media is unreadable.

On the other hand, a system backup is exceedingly handy for getting you back up to speed with minimal hassle. It returns your system to exactly where you were at the time of the backup: OS, program, updates, upgrades, settings, data are all back in a relative blink of the eye.

But it’s not essential. While reinstalling operating systems, drivers, and programs, as well as adjusting settings require more effort, you can then recover your data if that’s all you backed up. See the first paragraph.
