The 7 Best Backup Solutions for 2024: Cloud, Local, and Free Options Compared

Most people do not think about backups until they need one. By then, it is usually too late. Hard drives fail at an annual rate of roughly 2% in their first three years, ransomware encrypts files in seconds, and accidental deletions happen with a single misplaced click. The question is not whether you will lose data, but when, and whether you will have a backup when it happens.

This guide covers the seven best backup solutions across three categories: full disk imaging software for creating exact copies of your entire system, cloud backup services for off-site protection, and free built-in tools that cost nothing to use. We also explain the 3-2-1 backup rule, the industry standard for data protection, and how to apply it with a mix of the tools listed here.

The 3-2-1 Backup Rule Explained

The 3-2-1 rule is the simplest framework for ensuring your data survives almost any disaster. It states that you should have three copies of your data, on two different types of storage media, with one copy stored off-site. Here is what each number means in practice:

Three copies: Your original working data plus two backups. If your computer dies, you still have two copies. If one backup fails, which happens more often than people expect, you still have one. Two backups is the minimum that provides redundancy against both primary device failure and backup corruption.

Two different media types: Do not store both backups on the same type of device. If both backups are on hard drives from the same manufacturing batch, a common defect can kill both simultaneously. Use one local external drive and one cloud backup, or one NAS and one external SSD. The point is diversity of failure modes.

One off-site copy: A backup sitting next to your computer is vulnerable to the same fire, flood, theft, or power surge that destroys the computer. An off-site copy, whether in the cloud or on a drive stored at a different physical location, survives localized disasters. Cloud backup services handle this automatically by storing data in geographically distributed data centers.

Applying the 3-2-1 rule with the tools in this guide: use Acronis or EaseUS for a local disk image on an external drive (copy two), Backblaze or IDrive for a cloud backup (copy three, off-site), and your computer is the original. Total cost: approximately $100 for an external drive plus $7 per month for cloud backup. That is roughly $184 for the first year to protect against ransomware, hardware failure, theft, and natural disaster.

Rankings Comparison Table

1. Acronis True Image: Best Full Disk Imaging with Ransomware Protection

Acronis True Image is the most complete backup solution available. It creates sector-by-sector disk images that capture your entire system including the operating system, applications, settings, and files. Restoring from an Acronis image rebuilds your computer exactly as it was at the time of backup, down to the desktop icon positions. For disaster recovery where you need to replace a failed drive or migrate to a new computer, disk imaging is dramatically faster than reinstalling Windows, all applications, and then recovering files.

The ransomware protection feature distinguishes Acronis from competitors. It monitors file system behavior in real time, detecting patterns associated with ransomware encryption: rapid creation of files with known ransomware extensions, modification of large numbers of files in sequence, and modification of backup files. When ransomware behavior is detected, Acronis terminates the process, blocks the executable, and restores affected files from the most recent backup automatically. In controlled tests, Acronis blocked 100% of ransomware samples before any files were permanently lost.

Cloud backup is included in the Advanced subscription at $49.99 per year for 500GB of storage, with upgrade options up to 5TB. The backup chain supports incremental and differential backups, meaning only changed blocks are uploaded after the initial full backup. Encryption is AES-256 for local backups and SSL during cloud transfer. Version history is unlimited within the retention rules you set, so you can recover files from any point in time without storage volume constraints.

2. EaseUS Todo Backup: Best for Beginners and Budget Disk Imaging

EaseUS Todo Backup offers disk imaging, file backup, and system clone capabilities in a cleaner, more approachable interface than Acronis. The home screen presents four large tiles: Disk/Partition Backup, File Backup, System Backup, and Smart Backup. For users who find Acronis's extensive feature set overwhelming, EaseUS offers 90% of the capability at 80% of the price.

System clone is a standout feature for hardware upgrades. It creates an exact copy of your system drive that can be written directly to a new SSD or hard drive, making the upgraded drive immediately bootable without reinstalling Windows or any software. This is the fastest path from an old hard drive to a new SSD for anyone replacing their computer's storage.

Cloud backup is available as an add-on at $23.95 per year for 50GB or $47.95 for 200GB. Encryption is AES-256 for local backups. The backup scheduling is flexible, supporting continuous, hourly, daily, weekly, and event-triggered backups. At $39.95 per year for the Home edition, EaseUS costs $10 less than Acronis while covering the same core disk imaging functions, making it the better value if you do not need Acronis's ransomware protection module.

3. Backblaze: Best Unlimited Cloud Backup

Backblaze is the simplest cloud backup service on the market. Install the application, and it automatically backs up everything on your computer except the operating system, applications, and temporary files. There are no decisions about which folders to include, no storage limits, and no tiered pricing based on data volume. One computer, one price, unlimited data.

The straightforward pricing model eliminates the anxiety of calculating backup size before subscribing. Photographers with 3TB of RAW files, video editors with 5TB of project data, and users with multiple large external drives all pay the same $7 per month or $99 per year. Backblaze supports external drives connected via USB and backs them up automatically. Drives that are disconnected for more than 30 days have their backups removed unless you enable extended version history.

Restore options set Backblaze apart. You can download files individually through the web interface, request a ZIP archive of specific folders up to 500GB, or order a USB flash drive (256GB, $99 refundable) or USB hard drive (up to 8TB, $189 refundable) with your data shipped via FedEx. The shipped drive option is free if you return the drive within 30 days. Encryption uses AES-128 by default with an optional private encryption key that Backblaze cannot recover if lost. The standard plan retains deleted and changed files for 30 days, extendable to one year or forever for an additional fee.

4. IDrive: Best Hybrid Local and Cloud Backup

IDrive covers both local and cloud backup in a single subscription, which is rare among backup services. The Personal plan includes 5TB of cloud storage and supports unlimited devices under one account. A single subscription backs up Windows PCs, Macs, iPhones, iPads, and Android devices, making it the most efficient option for households with mixed device ecosystems.

The local backup feature uses IDrive Express for initial seeding. Rather than uploading terabytes over a residential internet connection, IDrive ships you a physical storage device that you back up to locally and mail back. The data is then loaded into your cloud account. This avoids weeks of continuous upload on slow connections. Subsequent backups are incremental, uploading only changed blocks.

IDrive retains up to 30 previous versions of each file, so you can recover from ransomware encryption, accidental modification, or file corruption by rolling back to a point before the change. Encryption uses AES-256 with an optional private key that IDrive does not store. At $79.50 per year for 5TB with unlimited devices, IDrive offers the best value per terabyte per device combination in the backup market.

5. Carbonite: Best for Hands-Off Automated Cloud Backup

Carbonite positions itself as the backup service that requires the least user interaction. After installation, it backs up the Documents, Photos, Music, and Desktop folders automatically. You can add folders by right-clicking them in Windows Explorer and selecting "Back up with Carbonite." There is no complex scheduling, no retention policy configuration, and no backup type selection. The philosophy is that backup should happen without you needing to manage it.

This simplicity comes with limitations. Carbonite does not back up files larger than 4GB on the Basic plan, which excludes video files and disk images. External drives require the Plus plan at $111.99 per year. Video files are excluded from automatic backup entirely on the Basic plan and require manual selection on higher tiers. Version history is limited to 30 days, shorter than Backblaze's standard 30 days and IDrive's 30 snapshots.

For users who want a backup they never think about, Carbonite delivers. For users who need to back up large media files, external drives, or system images, Backblaze or IDrive provides more flexible storage at a lower price. Carbonite's strength is eliminating decision-making, not maximizing storage capacity or feature breadth.

6. Windows File History: Best Free Local Backup

Windows File History is built into Windows 10 and 11 at no additional cost. It backs up files in your Libraries, Desktop, Contacts, and Favorites folders to an external drive or network location on a schedule you configure, from every 10 minutes to daily. When you need to recover a file, the File History interface displays a timeline of versions with previews.

The tool does not create disk images, cannot back up the operating system, and does not offer cloud storage. It is a file version history tool, not a system recovery tool. For protecting work documents, photos, and personal files against accidental deletion or modification, it works well within its limited scope. Combined with a cloud backup service for off-site protection, File History handles the second copy in a 3-2-1 strategy without spending money.

Setup requires an external drive and a few minutes of configuration. In Settings > Update & Security > Backup, select your external drive and File History activates. The initial backup copies all selected files, and subsequent backups only copy changed files. File recovery is done through the "Restore your files with File History" option in Control Panel, which presents a familiar File Explorer-style interface with a timeline.

7. Mac Time Machine: Best Free Local Backup for Mac Users

Apple's Time Machine is the best free backup tool on any operating system. Connect an external drive, confirm you want to use it for Time Machine when prompted, and the system handles everything else. Time Machine creates hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for previous months. When the backup drive fills, older backups are deleted automatically.

Time Machine backs up the entire system, including applications, system files, accounts, preferences, and documents. A full system restore from a Time Machine backup rebuilds the Mac exactly as it was at the time of the last backup, with all applications, settings, and files intact. The restore process is integrated into macOS Recovery, accessible by holding Command+R during startup.

The interface for recovering files is visually intuitive. Enter Time Machine from the menu bar, and Finder displays a stack of windows receding into the background, each representing a backup snapshot. Navigate through folders and use the timeline to find the version you want. Time Machine supports encrypted backups with a password or recovery key for users who need data at rest protection on the external drive.

Pros and Cons at a Glance

Which Backup Solution Should You Choose?

For most users, the best backup strategy combines two tools: a local disk imaging solution and a cloud backup service. Acronis True Image for local full-system backups on an external drive plus Backblaze for unlimited cloud backup costs approximately $149 per year total. This setup satisfies the 3-2-1 rule and protects against hard drive failure, ransomware, accidental deletion, theft, fire, and natural disaster.

Users on a tight budget can achieve 3-2-1 protection for free using Windows File History or Mac Time Machine for local backup to an existing external drive, combined with a free tier or highly discounted cloud service. The external drive is the only mandatory hardware purchase, and even a $50 1TB USB drive provides adequate capacity for most users' essential files.

The one mistake to avoid is doing nothing. Even Windows File History on an old external drive is dramatically better than no backup at all. A $50 external drive used with free built-in tools protects against the most common data loss scenarios. Add a cloud backup when budget allows, and you have a professional-grade data protection strategy for under $150 per year.
