8 Best Free Backup Software Picks in 2026

You don't have to restore an entire computer just to recover one document. Veeam Agent combines image-based backup with file-level recovery, and its free edition can create bootable recovery media. That makes it a better starting point than a folder-only program when replacing a failed Windows drive is part of your plan. The official free-product page lists external drives, NAS shares, and Veeam repositories as destinations.

The catch is its job count. Free gives you one job per protected computer, so separate schedules for a project folder and the whole system don't fit neatly into the free edition. A 2025 Veeam community discussion confirms that pointing another job at a licensed backup server doesn't remove the standalone client's restriction.

I'd choose the system image for that one job, then use file-level restore when necessary. The download process also asks for account details, which adds friction compared with an open-source direct download. Commercial editions add management and other capabilities; Veeam's prices depend on the product and licensing arrangement, so check its official comparison instead of treating a business-suite price as the cost of this client.

Pick it if you want one free Windows backup job that covers a computer recovery. Skip it if you need several independent jobs with different targets and schedules.

Time Machine keeps hourly, daily, and weekly history automatically. Apple also documents an encryption option during disk setup. For a Mac owner with a spare external drive, that combination avoids a surprisingly long list of decisions about formats, schedules, and storage accounts. It's included with macOS, without a subscription or a separate premium version. Apple's setup instructions explain the current controls and supported storage approach.

A January 2026 Apple-help discussion began with an initial backup taking days. After commenters suggested checking the drive and cable, the original poster switched to another disk and reported a much faster backup. That is a good reminder to examine the storage path before spending a weekend changing software settings.

My reservation is geographic: the drive beside your Mac doesn't help if both disappear together. Time Machine also isn't a general client for whichever object-storage account you already have. If you want that second remote copy, Duplicati or Kopia can handle selected folders alongside it. Don't expect Time Machine's interface to become a cross-platform backup manager for the Windows machines in the same household.

Pick it if your main computer is a Mac and you want automatic local history. Skip it if you need one program to cover Macs, Windows PCs, and a cloud bucket.

Duplicati separates its free backup client from its optional hosted console. You can use the client without buying a console plan. Its current source repository lists Windows, macOS, and Linux, a graphical interface, a command-line client, and destinations including SFTP, WebDAV, S3, and several storage vendors.

That's a strong match for website projects: source folders, exports, and assets can go to storage you already control. Its destination choices are broader than the built-in Windows and Mac tools. The client runs the backup work on your computer and sends the resulting backup data to the location you choose.

The weakness is setup complexity. You'll need destination credentials and a retention plan, and provider-specific settings can interrupt what initially looks like a simple wizard. This isn't my first pick for recovering an installed Windows system after its drive fails. Veeam handles that task more directly.

Duplicati publishes separate console pricing: the Free console monitors two machines and shows the last 200 backups. Paid console plans add capabilities such as remote management and alerts. Those console limits don't mean the free desktop client can back up only two computers. Cloud storage costs depend on your destination.

Pick it if you want scheduled folder backups to your own local or remote storage. Skip it if your priority is a full-PC image and bootable recovery workflow.

File History is still documented for Windows 10 and Windows 11. Microsoft places its setup in Control Panel under System and Security, where Save backup copies of your files with File History opens the feature. It can use an external drive or a network location, and folders outside the standard set can be included through a library. Microsoft's current instructions also explain restoring earlier versions.

I'd use it for a computer whose important work lives in Documents, Desktop, and a few clearly organized project folders. There's no extra client to keep updated and no billing plan to decode. Restoring yesterday's copy of a file is a smaller job than rebuilding a system from an image.

Its weakness is coverage. File History doesn't replace an image of Windows and installed applications, and a folder outside the included libraries needs attention. A drive that contains backups of Documents can still omit the project stored somewhere else. Before relying on it, check that your actual working folder appears in its recoverable history.

The feature costs nothing beyond your Windows installation and destination storage. There isn't a File History Pro subscription that expands it into a complete server or cloud-backup product.

Pick it if you need earlier versions of a few Windows folders. Skip it if you want operating-system recovery or a direct cloud-storage destination.

Kopia can identify the same content after a file moves or changes name, avoiding another upload of unchanged data. Its snapshots use deduplication, and its policies control exclusions, scheduling, compression, and retention. Kopia's feature documentation also describes an official graphical interface, so you don't have to begin at a terminal.

I like its model for a growing collection of website exports and assets. A repository holds the history, and policies describe what happens to different folders. You can place that repository on local storage, a network path, or a supported remote backend. The software is free and open source; it doesn't include a paid allocation of storage.

The learning curve is the weakness. “Repository,” “snapshot,” and “policy” aren't hard concepts, but they add decisions compared with choosing one disk in Time Machine. The Kopia FAQ and installation pages are worth reading before building a multi-computer arrangement. Some cloud connections require Rclone as an additional component.

In a January 2026 self-hosting discussion, users praised its encrypted, incremental backups while describing the interface as less appealing than the backup engine. One Windows user also found that disconnecting a repository to create another interrupted the snapshot workflow. I'd start with a single destination before adding more.

Pick it if you want detailed snapshot policies without buying a desktop license. Skip it if repository management sounds like work you'd keep putting off.

AOMEI Backupper offers a free Standard edition alongside Professional and business products. Its edition page lists file, system, disk, and partition backup, while marking options such as differential backup and advanced synchronization for paid editions. Its cloud-storage trial is separate from the free local-backup program.

I'd consider Standard for a Windows owner who wants several recognizable backup types in one application. You can see the difference between protecting a folder and imaging a disk without first learning a command syntax. The clear Windows focus also makes it less complicated than installing a server for one laptop.

The weakness is that the free and paid features share the same product pages and interface. An advertised capability isn't automatically included in Standard. System cloning, for example, shouldn't be confused with free system backup, and the page specifically limits free disk cloning to data disks.

In July 2025, a backup discussion about Windows crashes reported that AOMEI support identified its driver during backups to an external UASP drive. The poster removed AOMEI and reported that another backup program then worked. I'd avoid keeping several imaging packages installed while troubleshooting a driver problem.

Standard is free. Paid editions have different license offers; check the official edition page for the billing and upgrade terms of the offer you intend to buy.

Pick it if you want a Windows interface with free file and image backups. Skip it if you want an entirely open-source product or fewer upgrade prompts.

Rescuezilla boots into its own graphical environment and can back up a disk while the installed system is offline. Its images are compatible with Clonezilla. The official site lists version 2.6.2, released May 15, 2026, with continued project releases.

This is the option I'd keep available before a risky disk migration. You can start it from USB even when Windows or Linux won't boot, then work with an image stored on another device. It doesn't require installing a backup client inside the broken operating system.

The weakness is automation. Rebooting into a rescue environment doesn't fit an hourly background schedule, and hardware detection matters. A June 2025 GitHub report describes a 320 GB HDD refusing to clone to a 256 GB SSD even with only 195 GB in use. The poster got cloning started after changing the partition layout and destination choices, then asked how to check that the files were intact. Rescuezilla's smaller-disk procedure addresses the partition preparation.

The application is free open source, with donations supporting development. There is no paid feature edition. It works on compatible PC hardware; a bootable PC rescue environment shouldn't be assumed to work on every Mac architecture.

Pick it if you need an offline disk image or a recovery environment. Skip it if you want unattended daily folder backups while your computer remains in normal use.

UrBackup uses a server and clients, with a web interface that shows backup status and lets you browse recoverable files. Its feature list covers Windows, Linux, and FreeBSD clients, file and image backups, deduplication between computers, and missed-backup alerts.

I'd choose it for a small group of computers when someone is willing to maintain the backup server. You get a place to notice that a laptop hasn't backed up in a while, instead of opening eight separate applications. That administration model is its main attraction, especially if your household or office already has an always-on machine.

It is excessive for one laptop and one USB drive. Image support also has filesystem restrictions, which the project lists explicitly. A June 2025 internet-restore discussion revealed a less obvious problem: one participant had reduced the active-client setting below their client count, leaving no slot for a restore. Increasing the setting resolved that participant's connection problem.

The server and clients are free open source. UrBackup links commercial services separately, and running the server means supplying its storage, updates, and availability yourself.

Pick it if you want centrally managed backups of several computers. Skip it if you don't want another service to maintain.
