Best Cloud Backup: Top Services and How to Choose

For most people, Backblaze Personal Backup is the best cloud backup service: it offers straightforward, continuous computer backup with unlimited storage for one computer, making it easy to protect a large library without managing file quotas. Choose a different service if you need multiple devices, built-in file syncing, or more control over retention and backup settings.

What to Look For

Cloud backup copies files to remote servers so they can be recovered after a device is lost, damaged, stolen, or affected by a local failure. It is not automatically the same as cloud storage or file syncing: a synced deletion or unwanted change may also reach other devices. A strong setup keeps independent, recoverable copies.

• Coverage: Check which computers, external drives, phones, and operating systems are supported. “Unlimited” often applies only to a specified computer or plan, not every device you own.
• Restore options: Look for clear ways to download selected files or recover a large collection, and check whether physical-drive recovery is offered, where available.
• Version history and deletion retention: Find out how long older file versions and deleted files remain recoverable. A short window can be a problem if you discover damage late.
• Security and account recovery: Check encryption practices, two-factor authentication, and how private-key encryption affects account recovery. A forgotten private key can make encrypted backups inaccessible.
• Backup behavior: Continuous or scheduled backup, external-drive support, exclusions, and bandwidth controls affect how reliably the service fits your routine.
• Total cost and limits: Compare the number of covered devices, storage caps, renewal terms, and any restore or retention restrictions. Confirm current plan details before buying.

Backblaze Personal Backup

Strengths: Backblaze is a simple choice for backing up one Windows or Mac computer. Its personal-computer plan is known for unlimited backup storage per computer, automatic backup, and a relatively hands-off setup. It can also back up attached external drives, subject to the service’s connection and retention requirements.

Trade-offs: It is not a general-purpose folder-sync service, and its unlimited coverage should not be mistaken for unlimited devices. Check the current rules for external drives, deleted files, version history, and restore methods; those details can determine whether it suits your archive.

Best for: Someone who wants an uncomplicated off-site copy of one computer and does not want to decide which files fit a storage quota.

IDrive

Strengths: IDrive is a flexible option when you need to back up several computers and other supported devices under one account. It combines backup features with file syncing, and supports a range of platforms and backup configurations. Its storage plans have defined limits, so you can compare the allowance with your actual data.

Trade-offs: You must keep an eye on storage use, and its many options can take more setup than a minimal service. Syncing and backup are separate functions, so understand which one protects each folder and how retention works before relying on it.

Best for: Households or small offices protecting multiple devices, especially when a single account is more useful than unlimited storage for just one computer.

CrashPlan

Strengths: CrashPlan is aimed primarily at business and professional computer backup. It offers configurable backup policies and retention options that can suit organizations needing more control than a basic consumer plan provides.

Trade-offs: It is not the most natural pick for a casual home user, and plan availability, device coverage, and management features depend on the product tier. Review its current business terms and supported platforms rather than assuming consumer features match those of other services.

Best for: Small organizations or professionals who want managed computer backup and are comfortable evaluating business-oriented settings.

Microsoft OneDrive

Strengths: OneDrive is convenient for Windows users who want files available across devices and integrated with Microsoft 365. It can protect selected folders and offers versioning and recycle-bin recovery features, with limits and retention depending on account type and current policy.

Trade-offs: OneDrive is primarily cloud storage and synchronization, not a complete image-based backup of a computer. Changes and deletions can sync, and your included storage is finite. Keep a separate backup for files that must survive beyond the service’s recovery windows.

Best for: People who value easy access to working documents across devices and already use Microsoft’s ecosystem, rather than those seeking a full system backup.

Apple iCloud

Strengths: iCloud is a convenient way to sync and protect selected Apple data, including supported iPhone and iPad backups, photos, and files. It works smoothly within Apple devices and can make replacing or restoring an iPhone easier.

Trade-offs: iCloud storage is shared across services and is limited by the plan you choose. iCloud Photos and iCloud Drive synchronize data; they should not be treated as an independent archive of every original file. Windows and non-Apple workflows are less seamless than an Apple-only setup.

Best for: Apple users who want device backup and convenient syncing, ideally alongside another copy of irreplaceable photos and documents.

How to Choose

Start with what must be recoverable. If the priority is a whole computer’s personal files, choose a dedicated backup service such as Backblaze or IDrive. If you mainly need documents accessible on several devices, OneDrive or iCloud may be enough for syncing, but add a separate backup for important data. A business with multiple employees may need CrashPlan or another service built for administration and retention controls.

Match the plan to your devices and data. Count computers, estimate the space used by photos and video, and note whether external drives need protection. An unlimited plan for one computer may be a poor fit for a family with several laptops. A capped multi-device plan may be better value if your total data is modest.

Decide how much control you want. Automatic backup is easier to maintain; scheduled backups and detailed policies offer more control but require attention. Check how the service handles disconnected drives, excluded folders, long-offline computers, and files you delete.

Consider recovery before price. A backup matters only if you can restore it. Look up how to retrieve a few files and how to recover a large library, whether restores incur a charge, and what happens if you lose your password or encryption key. For critical data, keep another copy on a separate drive or service: cloud sync alone is not a complete backup strategy.

Then compare the current cost. Prices and plan terms change, so compare the current annual or monthly total, renewal terms, storage ceiling, and device count. Avoid paying for a feature you do not need, but do not choose a plan whose retention or coverage leaves your important files exposed.

Frequently Asked Questions

Is cloud backup the same as cloud storage?
Not necessarily. Storage and sync services keep files available across devices; backup services focus on recoverable copies and may preserve older versions. Some products do both, but their protections differ.

Is Backblaze really unlimited?
Its personal plan has been offered with unlimited storage per computer, but that does not mean unlimited computers or unrestricted treatment of every attached drive. Confirm current plan rules and retention terms.

Can cloud backup protect me from ransomware?
It can help if older, clean versions remain recoverable and an attacker cannot delete the backup. Protection depends on retention, account security, and service design; keep another separate copy for important files.

Should I back up an external hard drive?
Yes, if it contains data you cannot replace. Confirm that your provider supports it and learn how often it must be connected to remain included in the backup.

Do I still need a local backup?
It is wise for important data. A local external drive can make large restores faster, while an off-site cloud copy protects against events that affect your home or office.

Bottom Line

Backblaze Personal Backup is the strongest starting recommendation for one computer: its simple automatic approach and unlimited per-computer storage reduce routine decisions. Pick IDrive for multiple devices, CrashPlan for business-oriented control, or OneDrive and iCloud when syncing within their ecosystems is the main need. Whichever you choose, verify recovery and retention terms, then keep a second independent copy of irreplaceable files.
