👤 Who Is Backblaze For?

Backblaze fits teams and individuals who need recoverable copies rather than a second live system. The questions worth answering before you commit are restores cost time and sometimes egress fees and an untested backup is not a backup.

🏆 Our Verdict

Backblaze earns a 4.7/5 Noizz editorial rating. It covers backup and object storage for keeping copies of data off the machine that made it, which is the part worth judging it on: copies held away from the source system, and cheaper per terabyte than primary storage. The trade-off to weigh is restores cost time and sometimes egress fees. It is a fit for teams and individuals who need recoverable copies rather than a second live system, and a poor fit for anyone whose requirement sits outside that shape.

Backblaze is a cloud storage and backup company built around two distinct product lines: Computer Backup, a consumer-facing tool that continuously backs up an entire computer for a flat rate, and B2 Cloud Storage, an S3-compatible object storage service aimed at developers and IT teams building their own backup, archive, or media workflows. Its core positioning across both products is plain, predictable pricing paired with a level of transparency about its own infrastructure that's unusual for a storage vendor, most visibly through its public reporting on the hard drives it runs in its own data centers. That mix of simple pricing and public engineering data has made it something of a reference point in the broader storage industry rather than just another vendor. The two products share a philosophy even though they serve very different buyers: back up more, worry about it less, and don't hide the pricing or the operational reality behind a sales conversation.

Two Products, One Mechanism

Computer Backup runs as a lightweight background client on Windows and Mac that automatically finds and continuously uploads every file on the internal drive, attached external drives, and network-attached volumes the user points it at, without requiring the customer to select folders manually. It works on a flat per-computer rate rather than a per-gigabyte meter, which is a structural bet: Backblaze absorbs the storage cost variance across its customer base instead of passing it through line by line. Restoring is done either by downloading a zip through the browser, having a physical USB drive shipped, or using the mobile app to browse and pull individual files, which matters for people restoring after a lost or stolen laptop with no working local backup.

B2 Cloud Storage is a separate, S3-compatible object store accessed through Backblaze's own S3-compatible API, a native B2 API, or command-line tooling, which means most existing S3-oriented software, rclone, restic, Cyberduck, Veeam, and NAS backup agents from vendors like Synology and TrueNAS, can point at B2 with little more than an endpoint and credential change. Storage here is metered by capacity and transfer rather than sold as a flat per-computer rate, but Backblaze deliberately keeps a single storage class instead of the multi-tier structure, hot, infrequent-access, archive, that dominates the major clouds, trading fine-grained cost optimization for a pricing model that's easier to reason about upfront. That single-tier approach also simplifies the mental model for a team managing the bucket: there's no lifecycle-policy engine to configure just to avoid accidentally leaving data in an expensive tier, because there's only one tier to begin with.

Who It Actually Fits

Computer Backup fits solo professionals, freelancers, and households who want a genuinely unattended, everything-included backup for their machines and don't want to think about which folders matter, since the default behavior already covers essentially the whole drive. It also suits people uneasy about relying purely on cloud sync tools like Dropbox or iCloud for disaster recovery, since a sync folder isn't a real backup, it just propagates a delete or a ransomware encryption event to every copy. It is a weaker fit for anyone needing centralized backup management across many endpoints in an organization, since the consumer client is built around a single machine's local console, not a fleet.

B2 Cloud Storage fits teams that already run backup software, media asset pipelines, or static-hosting workloads that speak the S3 protocol and are looking for a lower-friction alternative to a hyperscaler bill dominated by egress and API-request charges. It's a natural fit for NAS owners doing off-site backup rotation, for developers hosting large media libraries behind a CDN, and for IT admins pointing enterprise backup software at an off-site target as the off-site leg of a 3-2-1 backup strategy. It fits poorly for workloads that need deep integration with a broader cloud ecosystem: serverless compute, managed databases, fine-grained IAM policies, or multi-region replication topologies that the major cloud platforms support natively and that Backblaze does not attempt to replicate.

The Honest Trade-Off

The single biggest trade-off with Computer Backup is that it is fundamentally a Windows and Mac desktop product; there is no first-party Linux backup client, which rules it out for anyone whose primary machine runs Linux, even though the B2 storage underneath is fully platform-agnostic and reachable from Linux via the API or CLI. The all-inclusive, unlimited nature of the backup also trades away granular control: because the client is built to just work by backing up nearly everything by default, users who want fine per-folder retention rules or selective archiving logic will find the interface comparatively basic next to dedicated enterprise backup suites. And because the whole product line runs as a flat-rate consumer offering, there's no native way to centrally manage backup policy across a fleet of machines the way IT-oriented endpoint backup tools do.

On the B2 side, the trade-off is breadth of platform, not price or reliability. A single storage class with no built-in lifecycle tiering means teams with genuinely cold, rarely touched archives may end up paying for storage that a deeper-tiered provider would let them park more cheaply over time. And because Backblaze is a much smaller company than the major cloud platforms, the surrounding ecosystem, the range of managed services, region choices, and native integrations, is deliberately narrower; teams building a full multi-service cloud stack around B2 alone will eventually hit gaps that a broader cloud catalog does not have.

Evaluating and Migrating to Backblaze

The cleanest way to evaluate Computer Backup is to install the client on one real machine, let the first full backup complete, then actually test a restore, ideally via the browser download and the mobile app, rather than assuming the backup is trustworthy just because the upload finished without error. Worth checking specifically: how the client handles files that change mid-backup, how it treats external drives that get disconnected and reconnected, and whether version history goes back far enough to recover from a slow-burning problem like silent file corruption that isn't noticed right away. For B2, the equivalent test is pointing an existing S3-compatible tool, rclone, a NAS backup job, or a Veeam repository, at a new bucket and running a full backup-and-restore cycle before decommissioning any existing target, since the whole value proposition rests on the S3 API compatibility actually holding up under real tooling rather than documentation claims.

Migrating onto B2 from an existing S3-compatible provider is usually a matter of re-pointing the endpoint URL and generating new application keys, then running a parallel sync, many teams use rclone's sync command for this, so the old and new copies coexist until the new target has been validated end to end. Backblaze's egress terms, including reduced-cost or no-cost paths available through certain partner network programs, are worth checking directly against current terms before migrating any workload where a large share of the expected cost comes from data leaving the bucket rather than sitting in it, since that egress profile is often the real deciding factor between storage providers. It's also worth running the migration against a subset of data first and comparing checksums on both ends before cutting production traffic over, since an object storage migration that looks complete in a dashboard can still leave partial or corrupted objects behind if a sync job gets interrupted.
