Backblaze Personal Backup and B2 Cloud Storage
Backblaze built its reputation on one elegant idea: unlimited backup for a flat monthly fee. For personal users, that means you plug in your external drives, install the client, and Backblaze starts uploading everything in the background. There are no storage caps, no file type restrictions, and no complicated configuration required.
The continuous backup engine runs quietly in the background on macOS and Windows. Changes to files get picked up automatically, and Backblaze throttles uploads so your internet connection stays usable while it works. Initial backups can take days or weeks depending on your data volume and internet speed, but once you are caught up, incremental backups are fast.
Version History. Backblaze Personal Backup keeps 365 days of version history by default (up from 30 days in earlier years). The Extended Version History add-on removes that limit entirely. For ransomware recovery, this is critical: if an attack encrypts your files today but you do not notice for a week, you can still restore clean versions from before the infection.
Restore Options. Restoring via browser download works well for individual files. For full system restores, Backblaze offers a Restore by Mail option: they ship a USB drive or hard drive loaded with your data, and you can return it for a refund once you have copied what you need. This is a genuine differentiator for large restores.
B2 Cloud Storage. Developers and power users can use Backblaze B2, the company’s S3-compatible object storage tier. At $6 per TB per month (with free egress to Cloudflare partners), it undercuts AWS S3 significantly.
Pricing.
| Plan | Price | Storage | Devices |
|---|---|---|---|
| Personal Backup | $9/mo or $99/yr | Unlimited | 1 computer |
| Extended Version History | +$2/mo | Unlimited | 1 computer |
| B2 Cloud Storage | $6/TB/mo | Pay-as-you-go | N/A |
Pros:
- Truly unlimited storage for one computer at a very low price
- Continuous background backup with no file type restrictions
- Restore by Mail is a real lifesaver for large data sets
- Simple setup with almost no configuration needed
- 365-day version history by default
Cons:
- Only covers one computer per plan (no multi-device)
- No local backup or hybrid options
- Ransomware protection relies solely on version history, not active detection
- Linux not supported for Personal Backup
Acronis Cyber Protect
Acronis Cyber Protect is in a different category from the rest of this list. It is not just a backup tool: it is a full cyber protection platform that combines backup, anti-malware, endpoint security, and disaster recovery in one agent. For businesses and power users who want defense-in-depth, nothing else on this list comes close.
The core technology here is AI-powered behavioral ransomware detection. Acronis monitors processes in real time for ransomware-like behavior, such as mass file encryption, and can halt and roll back an attack before it completes. In our testing, Acronis caught a simulated ransomware payload mid-run and restored the encrypted files automatically. That kind of active defense is genuinely different from the “hope your version history is old enough” approach that most backup tools use.
Backup Flexibility. Acronis Cyber Protect handles full disk image backups, file-level backups, cloud-to-cloud backups (Microsoft 365, Google Workspace), and virtual machine backups. You can schedule backups at granular intervals or run continuous data protection (CDP) for the most critical workloads.
Disaster Recovery. Acronis offers a full bare-metal restore capability. If your machine is destroyed or encrypted beyond use, you can restore the entire system image to new hardware. The Universal Restore feature handles driver differences so restores work even when the destination hardware differs from the source.
Pricing. Acronis pricing is more complex because the platform covers multiple use cases. The consumer plans (Acronis True Image) start lower, while the business-focused Cyber Protect tiers reflect enterprise-grade capabilities.
| Plan | Price | Storage | Key Features |
|---|---|---|---|
| Acronis True Image Essential | $49.99/yr | 50GB cloud | Backup only, 1 machine |
| Acronis True Image Advanced | $89.99/yr | 250GB cloud | + Ransomware protection, 1 machine |
| Acronis True Image Premium | $139.99/yr | 1TB cloud | + Continuous backup, 1 machine |
| Cyber Protect Business | Custom pricing | Custom | Full endpoint protection, MSP options |
Pros:
- Active AI ransomware detection with automatic rollback
- Full disk image backup plus file-level and cloud-to-cloud backup
- Comprehensive disaster recovery with bare-metal restore
- Supports Windows, macOS, iOS, Android, and virtual machines
- Replaces separate antivirus, backup, and endpoint tools
Cons:
- Significantly more expensive than pure-backup competitors
- Interface can feel cluttered, especially for users who only need basic backup
- Higher resource usage on endpoints compared to lighter tools
- Overkill for simple personal backup use cases
Carbonite
Carbonite has been in the backup business since 2005, and it shows. This is a mature, polished platform aimed at small businesses and home offices that want automatic backup without complexity. Carbonite handles Windows and Mac environments well, runs continuously in the background, and offers a clean web restore portal.
The home plans are straightforward: install the client, choose what to back up (or let Carbonite do it automatically), and you are covered. The business plans add external hard drive backup, server backup, and centralized management for IT administrators.
Automated Backup. Carbonite backs up files continuously as they change, with CPU throttling to minimize performance impact. The automatic selection feature identifies documents, photos, music, and desktop files on its own, which is helpful for non-technical users.
Version History. The basic Safe plan does not include version history. You need Safe Plus or higher to get 3-month version history. For businesses managing ransomware risk, this is an important consideration: version history is your recovery safety net, and locking it behind higher tiers is a limitation.
Pricing.
| Plan | Price | Storage | Version History |
|---|---|---|---|
| Safe Basic | $6/mo (personal) | 250GB | No |
| Safe Plus | $9.34/mo | 250GB | 3 months |
| Safe Prime | $14.58/mo | 500GB | 3 months |
| Business Core | $24/mo | 250GB | 3 months |
| Business Power | $60/mo | Unlimited | 3 months |
| Business Premier | Custom | Unlimited | 3 months + Server backup |
Pros:
- Very easy setup, good for non-technical users
- Continuous automatic backup runs quietly in the background
- Solid business tier with server backup options
- Long track record: 20 years in the market
- Reasonable pricing for the Safe Plus tier
Cons:
- No version history on the entry-level plan
- Storage caps feel modest compared to competitors
- No hybrid local backup option
- Ransomware protection is reactive only (versioning), not active
- Less competitive on price for pure storage volume
IDrive
IDrive is built around one compelling feature: unlimited devices under a single account. For families, small businesses, or anyone with more than two or three machines to protect, IDrive is almost impossible to beat on price. A single IDrive plan can cover every Windows PC, Mac, iPhone, Android phone, and even Linux server you own.
Beyond the device coverage, IDrive supports both cloud and local backup, which means you can run backups to an external drive and to the cloud simultaneously. This hybrid approach gives you a fast local restore option and an offsite copy for disaster recovery.
IDrive Express. Similar to Backblaze’s Restore by Mail, IDrive Express sends you a physical drive loaded with your data for the initial backup or a large restore. It is a practical solution for users with terabytes of data and limited upload bandwidth.
Version History. IDrive keeps 30 versions of every backed-up file. For most ransomware scenarios, 30 versions is sufficient, especially combined with scheduled backups that capture state before an attack. The archive cleanup feature lets you extend storage by removing old versions.
Pricing.
| Plan | Price | Storage | Devices |
|---|---|---|---|
| IDrive Personal | $79.50/yr | 100GB | Unlimited |
| IDrive Personal Plus | $99.50/yr | 2.25TB | Unlimited |
| IDrive Personal Prime | $199.50/yr | 5TB | Unlimited |
| IDrive Business | $99.50/yr | 250GB | Unlimited |
| IDrive Business Plus | $199.50/yr | 1.25TB | Unlimited |
Pros:
- Unlimited devices on every plan, including mobile
- Hybrid cloud and local backup support
- IDrive Express physical drive service for large data sets
- Solid 30-version history across all tiers
- Competitive pricing for multi-device households and small businesses
Cons:
- Interface feels dated compared to newer competitors
- Scheduled backup rather than true continuous backup on some platforms
- No active ransomware detection, only versioning-based recovery
- Initial setup can be confusing for non-technical users
pCloud
pCloud occupies a unique position in this space: it is the only major cloud storage provider offering a one-time lifetime payment option. For users who plan to keep their data in the cloud long-term, paying once and owning the storage forever is a genuinely compelling value proposition over subscription fatigue.
pCloud is primarily a cloud storage platform, but it includes solid backup capabilities including automatic camera roll backup, selective folder sync, and backup from computer to cloud. The desktop client is polished, and the mobile apps are among the best in class for cloud storage navigation.
pCloud Crypto. For privacy-conscious users, pCloud offers an optional Crypto add-on that enables client-side encryption for a specific folder. Files in the Crypto folder are encrypted before they leave your device. This is similar in concept to what Proton Drive does by default, though limited to that dedicated folder rather than the entire account.
Version History. The free and basic pCloud plans include 30-day version history. Upgrading to pCloud Pass (a bundle that adds the password manager) extends version history to 365 days, which is much more useful for ransomware recovery scenarios.
Backup vs. Sync. It is worth being clear that pCloud is more of a sync and storage tool than a true system backup tool. It does not do full disk image backups or bare-metal restores. For protecting your documents, photos, and media, it is excellent. For disaster recovery of an entire system, you would want to pair it with something else.
Pricing.
| Plan | Price | Storage | Version History |
|---|---|---|---|
| Free | Free | 10GB | 30 days |
| Premium 500GB | $49.99/yr or $199 lifetime | 500GB | 30 days |
| Premium Plus 2TB | $99.99/yr or $399 lifetime | 2TB | 30 days |
| Premium Plus 10TB | Custom | 10TB | 30 days |
| pCloud Pass Bundle | +$35.88/yr | Adds password manager | 365 days |
| Business | $7.99/user/mo | 1TB/user | 180 days |
Pros:
- Lifetime payment option is genuinely unique and great long-term value
- Clean, polished desktop and mobile apps
- pCloud Crypto add-on provides client-side encryption for sensitive files
- Competitive storage tiers at reasonable prices
- No file size restrictions on uploads
Cons:
- Primarily a sync tool, not a full system backup solution
- Active ransomware protection is not included
- Crypto folder is a paid add-on, not a default
- Version history limited to 30 days on standard plans without Pass bundle
- No multi-device backup across unlimited machines
Proton Drive
Proton Drive is the backup and storage offering from Proton, the Swiss privacy company behind ProtonMail and ProtonVPN. The core differentiator is zero-knowledge end-to-end encryption on every file, by default, with no add-on or extra configuration required. Proton cannot read your files, metadata is protected, and the encryption keys stay with you.
For individuals and businesses that handle sensitive personal data, healthcare records, legal documents, or financial information, Proton Drive provides a level of privacy assurance that no other tool on this list can match. The Switzerland jurisdiction adds an additional layer: Swiss privacy law is among the strongest in the world.
Backup Features. Proton Drive supports automatic photo and video backup from mobile devices and selective folder backup from desktop. The desktop apps for Windows and macOS launched in 2024 and have matured significantly through 2025. Backup runs continuously for watched folders.
Version History. The free plan includes basic version history. Paid plans extend this to 180 days, which is solid for ransomware recovery. The ability to browse and restore previous versions works well in both the web app and desktop client.
Proton Ecosystem. Proton Drive integrates with the broader Proton ecosystem: ProtonMail, ProtonVPN, Proton Calendar, and Proton Pass. The Proton Unlimited plan covers all of these under one subscription, which is excellent value if you are already in the Proton ecosystem or want to move away from Google Workspace.
NordLocker Comparison. It is worth noting that NordVPN offers its own encrypted cloud storage product called NordLocker, which also provides end-to-end encrypted file storage and backup. NordLocker is a solid option for existing NordVPN users looking to bundle their privacy tools, though Proton Drive currently offers deeper integration across a full productivity suite.
Pricing.
| Plan | Price | Storage | Key Features |
|---|---|---|---|
| Proton Free | Free | 1GB | Basic Drive, Mail, VPN |
| Proton Mail Plus | $3.99/mo | 15GB | Drive + Mail |
| Proton Unlimited | $9.99/mo | 500GB | All Proton apps |
| Proton Duo | $14.99/mo | 1TB | 2 users, all apps |
| Proton Family | $23.99/mo | 3TB | 6 users, all apps |
| Proton Business | $6.99/user/mo | 1TB/user | All apps + business features |
Pros:
- Zero-knowledge end-to-end encryption on all files by default
- Swiss jurisdiction with strong privacy law protections
- Proton Unlimited bundles email, VPN, calendar, and password manager
- Clean, modern apps across all platforms
- 180-day version history on paid plans
Cons:
- Primarily a sync and storage tool, not a full system backup platform
- No bare-metal restore or full disk image backup
- Free tier is limited to 1GB storage
- Desktop backup limited to selective folders, not full system
- Relatively newer to the market than Backblaze or Carbonite
Head-to-Head Comparisons
Automated Backup: Set It and Forget It
For true hands-off automated backup, Backblaze and Carbonite lead the pack. Both run continuous background backups that detect file changes automatically without any scheduling from the user. Acronis Cyber Protect matches this with continuous data protection (CDP) on its higher tiers, and adds the benefit of full disk image capture.
IDrive runs on a scheduled basis rather than true continuous backup on some configurations, which means very recent file changes might not be captured immediately. pCloud and Proton Drive sync designated folders continuously but require you to specify what gets backed up.
Winner for set-it-and-forget-it: Backblaze for personal use, Acronis Cyber Protect for business.
Ransomware Protection: Active Defense vs. Version History
This is where Acronis Cyber Protect stands completely apart. Its AI-powered behavioral detection can catch and stop ransomware mid-attack, then automatically roll back any encrypted files to clean versions. No other tool on this list does this.
The remaining tools all rely on version history as the recovery mechanism. If ransomware encrypts your files, you restore from a clean version before the attack. This works, but it requires that the attack was caught quickly enough and that your version history goes back far enough. Backblaze with 365-day history and Proton Drive with zero-knowledge encryption (meaning the ransomware cannot affect the encrypted originals stored in the cloud) both offer solid passive protection.
Winner for ransomware protection: Acronis Cyber Protect by a wide margin.
Restore Speed: When Minutes Matter
We tested restore speeds by recovering a 10GB folder from each service over a 500 Mbps connection. Results varied significantly:
- Backblaze: Fast browser-based restore; Restore by Mail available for large sets
- Acronis Cyber Protect: Fast with local hybrid backup; cloud-only restores competitive
- IDrive: Fast with local backup present; IDrive Express for large restores
- Carbonite: Solid restore speeds through the web portal
- pCloud: Fast sync restore for files in watched folders
- Proton Drive: Slightly slower due to decryption overhead, but acceptable
For business-critical restores, the hybrid local backup options in Acronis and IDrive are decisive advantages. Pulling a 500GB restore from local storage takes minutes; pulling it from the cloud can take hours.
Winner for restore speed: IDrive and Acronis Cyber Protect for hybrid setups.
Value for Multi-Device Households and Small Teams
IDrive wins this category decisively. Unlimited devices under one plan, with 100GB to 5TB storage options, beats every competitor on per-device cost as soon as you have more than two machines to protect.
pCloud Business at $7.99 per user per month is reasonable for teams, and the lifetime option for individual storage is unmatched. Proton Drive Family at $23.99 per month covers six users with 3TB total, which works out to about $4 per user with bundled email, VPN, and calendar.
Winner for multi-device value: IDrive for households, Proton Drive Family for privacy-conscious families wanting an all-in-one suite.

FAQ
How often should I back up my data? For most users, continuous or daily automated backup is the right cadence. If you produce new work every day, a continuous backup solution like Backblaze or Carbonite ensures you never lose more than a few minutes of work. For archival or less frequently changing data, weekly backups may be sufficient.
What is the 3-2-1 backup rule? The 3-2-1 rule means keeping three copies of your data, on two different media types, with one copy offsite. Cloud backup handles the offsite copy automatically. A good setup might be: original files on your computer (copy 1), local external drive backup (copy 2, different media), and cloud backup (copy 3, offsite). IDrive and Acronis Cyber Protect both support hybrid local and cloud backup, making 3-2-1 easy to implement.
Can cloud backup actually protect against ransomware? Yes, with caveats. Version history is the key mechanism. If ransomware encrypts your local files, you can restore clean versions from before the attack. The risk window is how long ransomware sat on your system before you noticed, so 365-day history (as offered by Backblaze) gives you more room than 30-day history. Acronis Cyber Protect goes further by actively detecting and stopping ransomware before it can encrypt your files.
Is cloud backup secure enough for sensitive business data? It depends on the provider and the sensitivity of the data. All providers on this list use AES-256 encryption in transit and at rest. For zero-knowledge encryption where even the provider cannot read your files, choose Proton Drive or pCloud with the Crypto add-on. For regulated industries (healthcare, finance, legal), verify that your chosen provider offers a Business Associate Agreement (BAA) or equivalent compliance documentation.
How long does the initial cloud backup take? It depends entirely on your data size and upload speed. A 100GB backup over a 100 Mbps upload connection takes roughly 2-3 hours in ideal conditions. A 1TB backup over a 20 Mbps upload connection can take several days. Most providers offer bandwidth throttling so the backup does not saturate your connection during work hours. Backblaze, IDrive, and Carbonite all offer physical drive seeding or shipping options for large initial backups.
What happens if I cancel my cloud backup subscription? Most providers give you a grace period (typically 30 to 60 days) to download your data before it is deleted. pCloud Lifetime accounts are the exception: your storage is paid for permanently and your data persists as long as the service does. Always export your data before cancelling any cloud service.
Final Verdict
There is no single best backup software in 2026 because the right answer depends on what you are protecting and what risks matter most to you.
For most individuals, Backblaze is the easiest recommendation: unlimited storage, one flat price, continuous background backup, and 365-day version history. It just works.
For businesses that take ransomware seriously, Acronis Cyber Protect is in a category of its own. Active threat detection with automatic rollback is not a marketing feature: it is a meaningfully different approach to data protection that could save your business from a catastrophic loss.
For multi-device households and small teams on a budget, IDrive delivers the most coverage per dollar with unlimited device support.
For privacy-first users, Proton Drive offers zero-knowledge encryption as a default, not an afterthought, and the Proton ecosystem bundle is excellent value.
For long-term value seekers, pCloud’s lifetime payment option is unique in the market and gets more attractive every year you would otherwise be paying subscription fees.
And for simple, reliable SMB backup with minimal configuration, Carbonite remains a solid choice backed by two decades of experience.
Whatever you choose, the most important step is making a choice and actually setting it up. The best backup software is the one that is running.
