8 Best Backup Software in 2026 (Free and Paid, Tested)

Losing files is one of those things you never think about until it happens. A dead hard drive, a ransomware attack, or just accidentally deleting a folder you really needed – any of these can ruin your week. I’ve been there. Twice, actually.

After spending the last month testing backup solutions on both Windows and Mac, here’s what I found actually works in 2026. Some of these are free, some aren’t, and I’ll be upfront about which ones are worth paying for.

1. Backblaze – Best Overall Cloud Backup

Backblaze does one thing and does it well: it backs up your entire computer to the cloud without you having to think about it. No folder selection, no complicated schedules. Install it, and it starts uploading everything.

I ran Backblaze on my Windows desktop with about 1.2 TB of data. The initial backup took roughly 11 days on a 50 Mbps upload connection. After that, incremental backups happened silently in the background. CPU usage stayed under 3% during daily backups.

What I liked

  • Truly unlimited storage for one computer – no catches
  • Restores via download or they’ll mail you a USB drive ($99, refundable)
  • Mobile app lets you access any backed-up file from your phone
  • 30-day version history (extendable to 1 year for $2/month extra)

What I didn’t

  • Only backs up internal drives and one external drive at a time
  • No NAS backup – this is strictly for personal computers
  • Can’t do image-based backup (full disk clone)
  • If your computer is offline for 30+ days, backed-up files get deleted

At $99/year, it’s hard to argue with the value. If you just want peace of mind that your files are safe somewhere off-site, Backblaze is the answer for most people. I’ve recommended it to at least a dozen friends and none have complained.

2. Acronis True Image – Best for Power Users

Acronis tries to be everything at once: local backup, cloud backup, disk cloning, ransomware protection, and more. Honestly? It mostly pulls it off, though the interface feels busier than it needs to be.

The full disk imaging is where Acronis shines. I created a complete image of a 500 GB Windows installation in about 45 minutes to an external SSD. Restoring it to a new drive took roughly the same time. The image was bootable immediately – no driver issues, no activation problems.

What I liked

  • Full disk imaging with incremental updates
  • Both local and cloud backup in one tool
  • Active ransomware protection actually caught a test sample
  • Can clone drives directly (great for SSD upgrades)
  • Backup validation checks file integrity automatically

What I didn’t

  • Cloud storage caps out at 5 TB on the most expensive plan
  • Interface is cluttered – too many features fighting for attention
  • Annual pricing has crept up over the years
  • Some features like blockchain notarization feel like bloat

If you want both local imaging AND cloud backup from one app, Acronis is your best bet. Just ignore the features you don’t need.

3. Veeam Agent – Best Free Local Backup

Here’s the thing about Veeam: they’re a massive name in enterprise backup. Their free personal agent doesn’t get much marketing, but it’s genuinely excellent for local backups.

Veeam Agent for Windows (or Linux) gives you full image backup, volume-level backup, and file-level backup – all free. No trial period, no feature limitations on the core stuff. The catch? No cloud backup and no centralized management. For a single computer backing up to an external drive, that’s totally fine.

What I liked

  • Completely free with no strings attached
  • Recovery media creation is built in
  • Bare-metal restore works reliably (tested on different hardware)
  • Scheduling is flexible – daily, weekly, or custom
  • Low resource usage during backup operations

What I didn’t

  • No cloud storage option in the free version
  • Windows and Linux only – no Mac support
  • Interface looks very enterprise-y, which can be intimidating

For free local backups on Windows, Veeam Agent is the one I’d install on a family member’s computer. Set up a weekly image backup to an external drive and forget about it.

4. IDrive – Best Value for Multiple Devices

IDrive’s main selling point is backing up unlimited devices to one account. Where Backblaze charges per computer, IDrive gives you 5 TB (or 10 TB) shared across as many computers and phones as you want.

I tested it across a Windows desktop, a MacBook, and an Android phone. Setup was straightforward on all three. The initial backup speeds were noticeably slower than Backblaze – about 15-20% slower on the same connection. But for the price difference and multi-device support, that’s an acceptable trade-off.

What I liked

  • Unlimited devices on one plan
  • 5 TB for $79.50/year is competitive
  • Supports Windows, Mac, Linux, iOS, and Android
  • IDrive Express: they’ll ship you a physical drive for large restores (free once/year)
  • Snapshots protect against ransomware

What I didn’t

  • Upload speeds can be inconsistent
  • The 10 GB free plan is too small to be useful
  • Desktop app UI feels dated compared to competitors
  • First-year pricing is heavily discounted, then jumps up

If you need to back up a household of devices without paying per-device, IDrive makes the most sense financially. Just be aware of the renewal price increase.

5. Macrium Reflect – Best for Windows Disk Cloning

Macrium Reflect used to have a free version. They killed it in 2024, which was disappointing. But the paid version remains one of the most reliable disk imaging tools on Windows. Period.

I used Macrium primarily for migrating a 1 TB HDD to a 500 GB SSD. The intelligent cloning feature handled the partition resizing automatically and the entire process took about 90 minutes. Boot from the new SSD worked on the first try. That’s not always guaranteed with other tools – I’ve had cloning failures with cheaper alternatives that Macrium handled without issues.

What I liked

  • Disk cloning is rock-solid reliable
  • Differential and incremental image backups
  • Boot menu integration for pre-OS recovery
  • Backup verification catches corruption early

What I didn’t

  • No free version anymore
  • Windows only
  • No cloud backup option
  • Interface hasn’t been modernized in years

For pure disk cloning and local imaging on Windows, Macrium is the tool IT professionals tend to reach for. It’s not flashy, but it works when it matters.

6. Duplicati – Best Open Source Option

Duplicati is free, open-source, and surprisingly capable. It backs up to pretty much any cloud storage you already have – Google Drive, OneDrive, Dropbox, Amazon S3, Backblaze B2, SFTP servers, you name it.

The setup is web-based (runs a local server on your machine), which feels odd at first but actually works great. I configured it to back up my documents folder to Backblaze B2 with AES-256 encryption. The deduplication is smart – after the initial 40 GB upload, daily backups only transferred 50-200 MB of changes.

What I liked

  • Completely free and open-source
  • Works with 25+ storage backends
  • Strong encryption (AES-256) built in
  • Deduplication saves significant storage space
  • Runs on Windows, Mac, and Linux

What I didn’t

  • Web UI can be confusing for non-technical users
  • Database corruption issues happen occasionally (there’s a repair tool, but still)
  • No bare-metal restore – files only
  • Documentation could use improvement

If you’re technical enough to set it up, Duplicati with a cheap B2 bucket ($6/TB/month) gives you encrypted cloud backup for a fraction of what commercial tools charge. Not for everyone, but the price-to-capability ratio is unbeatable.

7. Carbonite – Best for Non-Technical Users

Carbonite has been around forever, and honestly, that’s part of its appeal. Your parents have probably seen Carbonite ads on TV. The software matches that audience – extremely simple, minimal options, just works.

I tested the Basic plan ($84.99/year). Installation took about 3 minutes. It automatically started backing up documents, photos, music, and desktop files. No configuration needed. The downside? The Basic plan doesn’t back up video files or external drives. You need the Plus ($139.99) or Prime ($179.99) plan for that.

What I liked

  • Absolutely minimal setup required
  • Unlimited cloud storage (with caveats on Basic)
  • Reliable automatic background operation
  • Good customer support with phone option

What I didn’t

  • Basic plan excludes video files – really annoying limitation
  • More expensive than Backblaze for less flexibility
  • Slow upload speeds compared to Backblaze and IDrive
  • No image backup capability
  • File size limit of 4 GB on Basic plan

Look, if you’re setting up backup for someone who will never open the settings panel, Carbonite works. But for most people reading this article, Backblaze gives you more for less money.

8. FreeFileSync – Best for Local File Syncing

FreeFileSync isn’t a traditional backup tool. It’s a file synchronization utility that mirrors folders between drives. Think of it as a smart copy tool that only transfers what’s changed.

I use FreeFileSync to sync my working project folders to a secondary NVMe drive every evening. A RealTimeSync feature watches for changes and syncs automatically, but I prefer running it manually via a saved batch job. Syncing 200 GB of files with maybe 2-3 GB of daily changes takes about 30 seconds.

What I liked

  • Completely free (donation edition adds a few extras)
  • Mirror, two-way, and update sync modes
  • Visual file comparison before syncing
  • Batch jobs for automated sync schedules
  • Handles millions of files without choking

What I didn’t

  • Not a true backup – no versioning, no encryption
  • No cloud support (local/network drives only)
  • If you delete a file on source, it deletes on target too (in mirror mode)
  • The donation nag screen on startup is mildly annoying

FreeFileSync fills a specific niche: keeping two local drives in sync. Pair it with a proper backup tool (like Veeam or Backblaze) and you’ve got a solid multi-layered backup strategy without spending much.

Which Backup Strategy Should You Use?

The old 3-2-1 rule still applies: 3 copies of your data, on 2 different types of media, with 1 copy off-site. Here’s what that looks like in practice:

  • Minimum viable backup: Backblaze ($99/year) and you’re done. Your files are in the cloud, encrypted, and you can restore anytime.
  • Better setup: Veeam Agent (free) for weekly local image backups to an external drive + Backblaze for continuous cloud backup. Total cost: $99/year.
  • Budget option: Duplicati + Backblaze B2. You’ll spend maybe $3-5/month depending on data volume, but setup takes more effort.
  • Multi-device household: IDrive 5 TB plan covers everything – computers, phones, tablets. One subscription, done.

The worst backup strategy is the one you never set up. Even just turning on free cloud storage for your most important folders is better than nothing.

How I Tested

Each tool was installed fresh on a Windows 11 machine with a 500 GB NVMe drive (roughly 280 GB used). I measured initial backup time, daily incremental backup time, CPU/RAM usage during backup, and restore time for a 10 GB test folder. Cloud backup speeds were tested on a 100/50 Mbps fiber connection. I also tested bare-metal restore where supported, using a different physical drive to confirm bootability.

FAQ

Is Windows built-in backup good enough?

Windows File History is decent for file versioning but limited. It doesn’t do full disk images, and Microsoft has been slowly deprecating their backup features. For basic file protection it works, but I wouldn’t rely on it as your only backup solution.

How much cloud storage do I actually need?

Most people have 200 GB to 1 TB of actual data worth backing up (after excluding OS files, programs, and temporary files). Unlimited plans like Backblaze remove the guesswork entirely. If you’re using a metered service, start with how much your Documents, Photos, and Desktop folders total.

Can I use Google Drive or OneDrive as a backup?

Technically yes, but sync services aren’t backup. If you delete a file locally, the sync deletes it from the cloud too. If ransomware encrypts your files, the encrypted versions sync up. A proper backup tool keeps versioned copies that survive these scenarios. That said, using cloud storage alongside a backup tool adds extra protection.

How often should I back up?

Cloud tools like Backblaze run continuously, so every file change gets backed up within hours. For local image backups, weekly is a reasonable default. If you’re working on something time-sensitive (a project deadline, tax season), bump it to daily.

What about Mac – do I still need backup software if I use Time Machine?

Time Machine is actually solid for local backup. It’s one of the few built-in backup tools I’d call genuinely good. But it only protects against hardware failure and accidents – not against theft, fire, or floods. Adding a cloud backup (Backblaze supports Mac) covers that gap.
