Research updated October 15, 2026. Prices are regional references, not a checkout guarantee. This is a documentation-and-independent-review comparison; we did not install these products, transfer test files or time a restore.
Cloud backup is the insurance policy for the moment a laptop fails, a ransomware incident encrypts local documents or a family photo drive disappears. The useful distinction is not merely how many terabytes a company advertises. It is whether the service takes scheduled independent copies, how long it retains changed or deleted files, and whether you can actually restore the right data to a replacement device. A cloud sync folder may mirror an accidental deletion; an online backup should preserve a recoverable earlier state according to its stated retention policy.
We compared eight currently released, purchasable backup services, not ordinary file-sync subscriptions: Backblaze Personal, IDrive Personal, Acronis True Image Advanced, Carbonite Safe Plus, CrashPlan endpoint backup, Arq Premium, Jottacloud Personal and Synology C2 Backup for Individuals. The comparison deliberately spans single-PC unlimited storage, multi-computer quotas, system-image recovery, business endpoint controls and a Norway-based option. Their capabilities are not interchangeable.

How we evaluated these products
Our transparent, weighted research-only editorial rubric is: recoverability and restore breadth 30%; versioning, ransomware resilience and deletion policy 20%; encryption, key custody and privacy 15%; device and destination compatibility 15%; transparent ongoing cost and quota rules 10%; and setup/administration plus support 10%. These weights reflect our editorial priorities, not lab measurements. We do not assign invented numerical test scores or rank throughput without a common independent benchmark.
We use the vendor’s live pricing, security and retention documentation as the primary source for product-specific claims. Independent professional reviews such as PCWorld’s October 2026 comparison, TechRadar’s tested service roundup, and Tom’s Guide’s 2026 guide provide practical context; different test dates, connection speeds and data sets mean their transfer observations cannot be merged into a single fabricated speed table. No vendor paid for placement in this editorial comparison.
What to verify before subscribing
First-year versus renewal: Convert promotional annual-equivalent monthly figures to the actual prepaid amount. Check whether sales tax, VAT, device count, extra TBs, extended version history, mailed restore drives and add-on security features are included. Prices here reflect publicly accessible US or European references on October 15, 2026; a Pakistan, EU or other regional checkout may differ or be unavailable.
Version history is the ransomware question: Ask what happens if ransomware modifies a file on Monday and you notice a month later. A 30-day deletion window, last-five-versions limit and year-long time window are different protections. Also ask how long a disconnected external drive remains restorable and whether a paused subscription deletes data.
Encryption has a recovery cost: Transport encryption, encryption at rest, user-controlled encryption keys and genuine zero-knowledge restore are distinct. Some services require you to provide a private passphrase during restore; others cannot help if you lose it. Choose an offline recovery-key storage method before uploading irreplaceable files.
NAS and mobile are not automatic: A Windows/Mac client, phone app that can browse restored files, true phone backup, server backup and NAS protection are five different capabilities. Check the exact platform and tier. Also check restore file-size limits and whether you need a local rescue disk to perform bare-metal recovery.
Practice the restore: After configuring scheduled backups, restore a random document and a nested photo folder to a different location, inspect their contents, and test access to an older version. If system-image recovery is essential, test recovery media on supported hardware. A second independent local copy is prudent; see our guide to keeping computer data safe. Cloud backup also complements, rather than replaces, malware prevention and the network-privacy protections discussed in our VPN comparison.
P001 — Backblaze Personal Backup: straightforward unlimited backup for one computer
Verified plan: Personal Computer Backup, US$99 per year on the vendor’s US pricing page, checked October 15, 2026. The annual price is per computer, not per household. The product automatically protects supported user files on a Windows or Mac computer and qualifying directly attached external drives; it is not a server, NAS or full-system-image subscription. Its greatest practical advantage is avoiding a capacity calculation before backing up a large photo or document library. A second computer means another license, so the economics reverse for a multi-PC family.
Recovery and versions: The standard retention window is 30 days for changed and deleted files. Backblaze’s current documentation says users can enable one-year history without extra storage charge; Forever history incurs US$0.006 per GB per month for older retained versions. The setting is not retroactive. A lost external drive must be handled promptly: a disconnected drive can disappear from the current backup view even when extended history remains accessible through the historical restore date. Recovery routes include downloaded restores and an optional mailed drive, subject to the then-current restore conditions. None of these claims implies we ran a restore ourselves.
Privacy and limitations: Backblaze encrypts data and offers an optional private encryption passphrase, but its documented restore workflow should be understood before describing it as seamless end-to-end, zero-knowledge recovery. A forgotten private passphrase can make recovery impossible. Check the vendor’s current restore/key handling rules, excluded files and operating-system permissions. Backblaze is our editorial fit for a single machine with lots of ordinary files, not for a Linux workstation or complex NAS estate. Sources: official pricing, version history, and encryption explanation.
P002 — IDrive Personal 5 TB: shared capacity across multiple computers
Verified plan: IDrive Personal 5 TB for one account and multiple computers. The vendor’s October 2026 US pricing page shows US$9.99/month reference and US$6.99/month equivalent with an annual discount, subject to billing selector and promotional eligibility; that discounted annual equivalent is about US$83.88, while US$9.99 times 12 is US$119.88 before discounts. Two-year offers are separate prepaid commitments. Do not mistake an introductory banner or a third-party US$4.98 promotion for the standard renewal. The capacity is a shared quota, not 5 TB per device, and IDrive has higher 10 TB and 20 TB personal tiers.
Backup rather than just sync: IDrive’s dedicated clients support scheduled file backup across supported Windows, macOS, Linux and mobile configurations; it also offers local backups, versioning, snapshots and courier-based seed or restore services under applicable conditions. Its sync capability is an extra, not the reason it qualifies here. A household with several laptops can use one pooled account, but it must account for the total source size, growth and retention overhead. Confirm whether external disks, NAS shares or system-image features are supported by the precise client and plan you choose, rather than treating the broad platform list as one universal feature matrix.
Encryption and restore: IDrive offers a user-chosen private encryption key at account setup. Its own security FAQ says IDrive does not retain that key, so losing it risks permanent loss of restore access; changing the key may require resetting the account and deleting existing cloud backups. The default-key option is less demanding but has a different key-custody model. Our editorial fit is a mixed-device household or freelancer who needs multi-machine backup and can manage a storage ceiling. Sources: current plan selector, key custody FAQ, and the independent PCWorld comparison (October 2026).
P003 — Acronis True Image 2026 Advanced: hybrid imaging plus a limited cloud allotment
Verified released edition: Acronis True Image 2026 Advanced, not Essentials. Acronis announced the 2026 release in September 2025. Its official comparison currently lists a US$72.99 starting annual Advanced subscription, 50 GB of cloud storage at the starting tier, and upgrade options up to 500 GB; device counts and storage selections change the final quote. Essentials starts at US$49.99 but has no cloud storage, so calling it a cloud-backup plan would be misleading. Premium starts at US$124.99 with 1 TB and can be configured for higher cloud quotas. The final regional checkout may differ from these US references.
What makes it different: Acronis combines file/folder and full-disk imaging, local backup destinations, cloud replication and security functions. For a Windows laptop where recovering installed applications, system settings and an operating-system image matters, that is a different job from restoring a folder of photos. Advanced also includes anti-malware features and selected Microsoft 365 backup functions. US-only identity protection should not be implied for international customers. Check whether a specific full-system restore is from a local image, a cloud image, or a recovery-media workflow; the existence of disk imaging does not mean a 50 GB cloud plan can store a 1 TB system.
Trade-offs: More knobs mean more decisions about backup destination, retention, security software overlap and recovery media. Acronis describes ransomware response and one-click recovery, but this roundup has not independently tested either. A recovery plan should include a local drive, an off-site copy and a practice restore. Our editorial fit is a user who prioritizes disaster recovery and imaging over the lowest price per TB. Sources: official tier comparison, features and platforms, and 2026 release confirmation.
P004 — Carbonite Safe Plus: unlimited storage with external-drive coverage
Verified plan: Carbonite Safe Plus for one Windows or Mac computer and one eligible external hard drive. The current US vendor comparison displays a promotional US$78.99 first annual year, compared with a US$131.99 regular annual reference. Carbonite’s renewal FAQ identifies US$131.99/year for Plus; do not present the discounted price as a guaranteed renewal. Basic is US$75.99 promotional versus US$95.99 regular but omits the same external-drive features; Prime’s US$96.99 promotion versus US$161.99 regular adds a courier recovery service under conditions. Each of these prices is for one computer, not unlimited machines.
Recovery behavior: Carbonite is built around automatic encrypted file backup, not a full system-image restore. Plus includes features such as external hard-drive backup and automatic video protection according to the vendor comparison. Carbonite’s own retention article says Safe Basic, Plus and Prime delete cloud copies of files removed locally after 30 days. That matters after ransomware, a mistaken folder deletion or a failed disk that stays disconnected while the user waits to troubleshoot. A plan with unlimited storage can still have a short deletion window.
Security and fit: Vendor documentation describes encrypted transfer and storage and different recovery options, but users should check operating-system differences, whether their desired folders are selected, and the consequences of any optional encryption-key setting. Carbonite is a viable alternative for a single home PC with an external photo drive, especially if an annual introductory promotion applies. It is a weaker fit for a fleet of computers or anyone expecting image-level bare-metal recovery. Sources: official current comparison, published regular-price reference, and deleted-file retention.
P005 — CrashPlan Endpoint Backup Small Business: policy-focused endpoint recovery
Verified plan: CrashPlan’s current US pricing page calls its under-250-employee endpoint offer Small business, listed at US$7.33 per user per month billed annually (US$88/year), or US$158 for two years. This is a released endpoint-backup product for Windows, macOS and Linux, not the separately priced Microsoft 365, Google Workspace or server service. It is especially relevant to a small creative studio with laptops that are difficult to rebuild from scratch.
Retention and pricing ambiguity: The same current vendor page’s endpoint feature block says unlimited cloud storage and unlimited versioning, but its FAQ also says endpoint subscriptions include 50 GB storage and describes additional storage at US$90/year per 250 GB. Those statements conflict. We therefore do not assume unlimited storage at checkout: obtain written clarification of the applicable SKU, contract and overage before purchase. The page also lists a 14-day trial with a card and automatic billing after day 14 unless canceled. An apparently low seat price is not a full total-cost estimate if a large dataset requires add-on capacity.
Operations: The offer emphasizes self-service restore and migration, centralized controls and policy-managed backups; enterprise capabilities such as custom storage, legal hold and advanced identity integrations are separately scoped. CrashPlan advertises ransomware recovery, but neither its marketing nor an editorial roundup substitutes for an actual recovery rehearsal. Our editorial fit is a small business willing to clarify the quota contradiction and administer multiple endpoints. It is not a default pick for someone seeking simple household photo storage. Sources: live endpoint pricing and contradictory FAQ and earlier product-line announcement, which should not override the current checkout.
P006 — Arq Premium: client-side encryption and five-computer flexibility
Verified plan: Arq Premium, US$69.99 per year, includes 1 TB of storage and licenses for five Mac or Windows computers. The vendor lists additional storage at US$0.00699 per GB per month, so a household storing 3 TB should not assume that its total cost stays at US$69.99. This is distinct from Arq 7, a US$59.99 per-computer application license that requires you to bring and pay for your own cloud storage. Arq Premium bundles the application and storage; Arq 7 does not.
Why advanced users choose it: Arq focuses on encrypted, scheduled backups, file history and restore access rather than general-purpose file sharing. The design suits people who care about where encryption occurs and want a dedicated backup tool instead of a sync folder. Before committing, inspect the exact private-password and encryption-key recovery documentation; a lost password or key can make a privacy-first backup impossible to restore. Check the supported source folders, external disks and client permissions on your actual Mac or Windows release. The plan does not advertise native mobile-device image backup or Linux desktop support.
Recovery economics: Its 1 TB included quota and five-device allowance create a different trade-off from Backblaze’s unlimited single-computer storage. An extra terabyte at the listed per-GB monthly rate can add roughly US$83.88/year if billed for a full 1,000 GB all year, subject to actual metering and units. We did not perform a restore or benchmark Arq’s throughput; our editorial preference here is for predictable cross-computer licensing and explicit encryption control. Source: official plan and expansion pricing; independent context: TechRadar’s cloud-backup methodology.
P007 — Jottacloud Personal Unlimited: Norway-based backup with a fair-use speed trade-off
Verified plan: Jottacloud Personal Unlimited, displayed at €12.90/month in the vendor’s current monthly selector for one user with backup across supported devices. A five-user Home 1 TB plan is displayed at €7.90/month, but it is a capped shared family plan, not the same unlimited Personal SKU. Annual billing may change the effective rate. The vendor explicitly says upload speed gradually decreases once stored data exceeds 5 TB. Therefore “unlimited” describes storage allowance, not an unlimited transfer-rate promise. Personal is also distinct from commercial Pro plans, which are licensed for business use.
Backup and versions: Jottacloud supports automatic backup, file and photo storage, an archive mode, and recovery of the last five versions of a file according to its own feature description. The service operates its infrastructure in Norway and highlights Norwegian and European data protection rules. It also offers sync and photo features; this article includes it because it has a real backup workflow, not because sync itself is a substitute for backups. A user who edits a document repeatedly should understand that five retained versions are a different safeguard from a time-based year-long version history.
Encryption caveat: Jottacloud encrypts data in transit and at rest, but its help center expressly says customers cannot specify their own private encryption keys. It should not be called user-held-key, zero-knowledge backup. Norway-based hosting is useful for data-residency planning, yet residency alone does not prove any particular legal or security outcome. Our editorial fit is a European individual prioritizing Norwegian storage and multi-device convenience who accepts the 5 TB throttling rule and limited version count. Sources: official prices, feature list, and key custody statement.
P008 — Synology C2 Backup for Individuals: cloud-based full-device restore without a NAS
Verified service: Synology C2 Backup for Individuals, a standalone cloud-backup subscription that does not require owning a Synology NAS. The vendor’s pricing selector offers 500 GB, 2 TB and 5 TB tiers with Europe/Frankfurt or North America/Seattle residency choices, but currently renders price placeholders to unauthenticated crawlers. A July 2026 G2 vendor-supplied pricing listing reports US$34.99/year for 500 GB, US$99.99/year for 2 TB and US$249.99/year for 5 TB; all three are provisional until region-specific checkout. They should not be mistaken for guaranteed renewal quotes.
Recovery scope: Synology positions C2 Backup as full-device backup with scheduled incremental copies, version history, file-level restore and bare-metal recovery. Its published documentation describes unlimited protected endpoints within a storage-based personal subscription; the quota is pooled, not per machine. A failed PC can be recovered through an appropriate recovery environment rather than just downloading selected documents. Verify exact Windows and macOS system-image behavior and supported hardware before relying on it for a bootable disaster-recovery scenario.
Privacy and plan boundaries: The ability to choose a European or North American data center is valuable, but a data-center selector is not a substitute for checking encryption, recovery keys, data-processing terms and account deletion policies. Synology updated its business C2 Backup packaging in June 2026; do not apply the new business-per-TB figures to the individual plan. Our editorial fit is a multi-device user seeking system-level recovery with a clear regional hosting choice, subject to verifying checkout. Sources: vendor individual plan selector, official product release, G2 July 2026 pricing reference, and June 2026 business-plan change.
Frequently asked questions
Is cloud backup the same as Google Drive or Dropbox?
No. Sync keeps working folders available across devices and can propagate unwanted changes. A backup plan is judged by scheduled independent copies, version history and restoration after deletion or device failure. Some products do both, but we evaluated their backup functionality.
Is unlimited backup really unlimited?
Usually it applies to storage for a specified computer or user, not devices, transfer speed, retention or commercial use. Backblaze and Carbonite limit their listed consumer licenses by computer; Jottacloud reduces upload speed after 5 TB. Always read fair-use and excluded-file terms.
What is the best option for ransomware recovery?
Prefer a service with a version window longer than your likely detection delay, plus an offline or isolated copy. A service cannot recover a version it has already deleted. Restore testing and secure account access matter as much as advertised ransomware detection.
Can I recover a complete computer from the cloud?
Some image-oriented offerings such as Acronis and Synology C2 advertise full-system recovery. Backblaze Personal and Carbonite Safe are primarily file-backup services. Recovery-media compatibility, the size of the cloud quota and the target computer must be checked before a disaster.
Do any providers guarantee zero data loss?
No provider should be treated as a guarantee. Retention limits, excluded folders, unsupported drives, failed schedules, lost private keys, subscription lapses and user errors can all prevent recovery. Keep independent copies and periodically perform a restore.
Editorial verdict
For a single ordinary computer with a large library, Backblaze’s US$99/year per-computer model is straightforward. For multiple machines under one subscription, IDrive’s shared 5 TB tier deserves the first price-and-restore comparison. For system images and malware protection, examine Acronis Advanced or Synology C2; for managed endpoints, clarify CrashPlan’s contradictory published capacity terms before purchasing. Carbonite, Arq and Jottacloud serve narrower but legitimate needs. The right choice is the one that restores your files under your actual failure scenario—not the one with the largest marketing number.
