Backblaze

Backblaze is the cloud backup brand people recommend when they are tired of explaining “tiers,” “hot storage classes,” and “you only get 100 GB unless you upgrade.” The consumer product—Computer Backup / Personal Backup—aims at one job: continuously copy the files on your Windows or Mac computer to Backblaze’s cloud for a flat, roughly monthly fee that feels unlimited for normal personal disks. Separately, Backblaze B2 is object storage for developers, NAS tools, and app backends. Confusing those two products is the number-one reason bad reviews happen.

This review is for US and UK individuals and freelancers deciding whether Personal Backup should sit next to (not instead of) a local Time Machine or Windows File History disk, and when B2 is the better checkout.

Quick verdict

Backblaze earns 4.6 / 5 for personal computer backup that you will actually leave running. Buy Personal Backup when you want off-site insurance for the documents, photos, and projects on one (or a few) computers without babysitting sync folders. Keep a local Time Machine / external disk for fast restores. Choose B2 when you need API storage, NAS sync targets, or app data—not when you merely want “unlimited laptop backup.” Skip if you need bare-metal imaging, corporate endpoint suites, or you refuse any cloud copy of your files.

STA score context: outstanding simplicity and value for consumer backup; not a full disaster-recovery suite and not interchangeable with B2.

What is Backblaze?

Backblaze, Inc. sells two related but distinct offerings that share branding:

1. Personal Backup (Computer Backup) — install a client on your Mac or Windows PC; selected data uploads continuously to Backblaze; you restore files through the web, client, or (for large recoveries) a shipped drive service where available. Pricing is famously flat-rate “unlimited” for the computer’s user data under the plan’s rules (exclusions and thread limits apply—read current help docs for external drive policies and excluded system files).
2. B2 Cloud Storage — S3-compatible-style object storage billed by usage. Tools like rclone, NAS apps, PhotoStructure, and custom apps use B2 as a bucket. This is not the same UX as the Personal Backup client.

Core jobs for Personal Backup:

• Quiet background upload after the initial seeding
• Version/history retention per current plan terms
• Recover individual files after ransomware, theft, or disk death
• Optional private encryption passphrase for client-side secrecy trade-offs

What Personal Backup is not: a two-way sync drive like Dropbox, a Time Machine replacement for bootable local snapshots, or a guarantee you can reimage a dead laptop to a brand-new machine in one click with every app setting intact. It backs up files; you still reinstall apps and rebuild environments.

Core features that matter

1. Unlimited personal backup positioning

The marketing hook is the flat fee for backing up a computer without counting gigabytes like a hawk. For photographers with large catalogs, video editors with project folders, and households that never delete Downloads, that pricing psychology matters more than another 200 GB Google One tier. Always verify what “unlimited” excludes: operating system files, certain temp paths, and how external/USB drives are handled on your plan year. Unlimited means “you are not nickel-and-dimed per GB for normal user data,” not “physics and fair-use vanish.”

For multi-computer households, you typically buy per computer. That is still often cheaper than bumping a sync suite to multi-terabyte tiers you only need for backup.

2. Continuous backup vs “I remembered to copy the disk”

Once installed and licensed, Personal Backup watches for changes and uploads when the machine is on and online. That beats the human ritual of Friday night external-drive copies you skip for three months. The first backup is the painful part: a multi-terabyte disk on a modest upstream ISP plan can take days or weeks. Plan a “seed week” where the computer stays awake; throttling controls help if you share a home connection.

3. Restore realities (download vs drive)

Restores are where expectations break. Downloading a few Word docs or a photo folder is easy. Rebuilding 2 TB over a home connection after a disk failure is slow and emotionally awful. Backblaze’s physical restore drive options (availability and fees vary by region—confirm for UK vs US) exist precisely for that bulk case. Practice a small restore before disaster: pick ten random files, recover them, open them. A backup you have never restored is a hypothesis.

Also understand scope: if ransomware encrypts your disk, cloud versions help only if retention covers the clean copies and your credentials were not used to purge the cloud. Enable account security (strong unique password + 2FA) and know how version history works on your plan.

4. Encryption and password caveats

Backblaze encrypts data in transit and at rest in its standard model. You can add a private encryption key / passphrase so that Backblaze staff cannot decrypt your files. That is the right choice for high-sensitivity data—if and only if you can store that passphrase in a password manager and never lose it. Forget the private key and Backblaze cannot politely “reset” plaintext for you. That is the point of private keys. People who write the key on a sticky note, then throw away the laptop bag, learn cryptography the hard way.

Default managed encryption is fine for many households who prioritize recoverability over zero-knowledge purity. Choose deliberately; do not toggle private encryption during a panic without recording the secret.

5. Personal Backup vs B2 (do not mix them up)

	Personal Backup	B2
Audience	Individuals protecting a PC/Mac	Developers, NAS, apps, archives
Pricing	Flat per computer (typical)	Pay for storage + egress patterns
Client	Official backup app	APIs, CLI, third-party tools
Mentality	Insurance for this machine	Building block storage

Buy Personal Backup for “my laptop might die.” Buy B2 for “my Synology / app needs a bucket.” Using B2 with rclone can approximate backup workflows, but it is a different product with different billing surprises (egress, lifecycle rules).

6. Local Time Machine + cloud: the sane stack

The professional answer in 2026 is still 3-2-1 thinking, simplified for home:

• Local: Time Machine (Mac) or File History / Windows Backup to a disk you own—for fast yesterday restores
• Off-site: Backblaze Personal Backup—for fire, theft, and “I left the NAS in the apartment that flooded”
• Optional archive: critical exports to a second location or cold B2 bucket

Cloud-only backup without a local disk means every restore waits on your download speed. Local-only backup without cloud means a burglary or house fire ends the story. Backblaze shines as the off-site leg, not as a religion that forbids external drives.

Hands-on / lab notes

Task	Result
Install on Mac + select user data	Low friction; exclusions worth reviewing
Initial 800 GB seed on ~40 Mbps up	Multi-day; leave Mac awake on power
Continuous incremental after seed	Quiet; barely noticeable on Wi‑Fi
Restore 25 photos via web	Fast confidence check—do this early
Private encryption passphrase drill	Store in Bitwarden; test understanding of trade-off
Compare vs Time Machine-only	Cloud wins for off-site; TM wins for speed
Confused B2 checkout by mistake	Easy to do—read product names carefully

Failure modes we still see: (1) cancelling the subscription after the first week because the seed “isn’t done,” then having no backup when the SSD dies in month four; (2) enabling a private key, forgetting it, and discovering the lesson during a restore; (3) assuming Backblaze cloned the OS and wondering why Office is missing after a new Mac setup; (4) buying B2 capacity thinking it was Personal Backup.

Pricing and editions

Product	Approx. 2026 pattern	Best for
Personal Backup (monthly/yearly)	Roughly high-single-digit to low-teens USD/month class per computer; yearly discounts common	Individuals / freelancers
Multi-computer	Per-seat Personal Backup	Households with two laptops
B2	Usage-based storage + download considerations	NAS, apps, archives
Business / groups offerings	Separate SKUs—verify current matrix	Small offices

Always check VAT for UK checkout, current external-drive rules, and restore-drive shipping fees. Backblaze’s consumer pitch remains “predictable,” which is why it scores well against suites that bury backup inside antivirus bundles with renewal spikes.

Who should buy it?

Buy Backblaze Personal Backup if you:

• Want set-and-forget off-site backup for a Mac or Windows PC
• Prefer flat pricing over counting sync-tier gigabytes
• Already have (or will add) a local Time Machine / external disk for speed
• Understand you are backing up files, not cloning a bootable system image

Skip or choose something else if you:

• Need enterprise endpoint management, DLP, and compliance dashboards
• Only want local snapshots and refuse any cloud copy
• Need Linux Personal Backup specifically—verify current platform support and consider B2 + restic/borg/rclone instead
• Actually need object storage APIs (buy B2 deliberately)
• Want one license that images five machines plus mobile phone camera rolls as a sync drive

Alternatives to consider

Alternative	Best when
Time Machine + external disk	Fast local restores; still add off-site separately
Acronis Cyber Protect Home	You want imaging + cyber features in one vendor
Backblaze B2 + rclone/restic	Power users / NAS who want open toolchains
iCloud / OneDrive / Google One	Sync and collaboration matter more than pure backup semantics
CrashPlan-style business backup	You need multi-user org policies

Final score: 4.6 / 5

Backblaze Personal Backup remains one of the easiest “sleep better” purchases for US and UK computer owners in 2026: flat-rate off-site insurance, continuous uploads, and restore paths that include bulk options when downloads would take forever. It is not B2, not Time Machine, and not a full system image tool. Used as the cloud leg next to a local disk—with a written-down plan for encryption keys—it earns a strong 4.6.

FAQ

Is Backblaze safe?
Yes as a reputable cloud backup provider when you use a strong unique account password, enable 2FA, and decide deliberately whether to use a private encryption passphrase you can never lose. Safety also means testing restores.

Personal Backup vs B2—which do I buy?
Personal Backup for protecting a Mac/PC with the official client. B2 for object storage, NAS, and developer workflows. They are different products.

Does Backblaze replace Time Machine?
No. Keep Time Machine (or Windows local history) for fast local restores; use Backblaze for off-site copies.

Is backup really unlimited?
Personal Backup is positioned as unlimited for typical user data under plan rules. Check exclusions, external drives, and fair-use docs for your account type.

What if I forget my private encryption key?
Backblaze cannot decrypt privately encrypted data for you. Store the key in a password manager. If that risk scares you, use the default encryption model instead.

How long does the first backup take?
Often days for large disks on home upload speeds. Leave the computer awake; after the seed, incrementals are much lighter.

Can I restore a whole computer like a clone?
You restore files and folders, then reinstall apps on a new or repaired machine. For bare-metal imaging, look at dedicated imaging tools.
