Wasabi vs Backblaze B2 for MSP Backups: Restore Math
Wasabi vs Backblaze B2 looks like a cheap storage fight.
That is the trap.
For MSP backups, the storage line is only the easiest number to quote. The real bill shows up in retention, immutability, restore testing, deleted data, egress policy, and the human work required when a restore is no longer theoretical.
If you sell backup storage as "$7 per terabyte, basically done," you are not quoting backup. You are quoting the calmest month of the year and hoping nothing gets weird.
Quick answer
Wasabi is usually cleaner when client backup data is steady, monthly downloads stay at or below active storage, and the MSP has modeled the 90-day minimum storage duration. Backblaze B2 is usually cleaner when restore testing or disaster recovery may create larger download spikes, because B2 includes free egress up to 3x average monthly storage and has no minimum storage duration.
That does not make one platform the universal winner.
It means the winner changes based on the restore pattern.
The headline storage price is basically a tie
As of June 2026, the public pay-as-you-go storage prices are close enough that MSPs should not pick from the headline rate alone.
| Cost factor | Wasabi Hot Cloud Storage | Backblaze B2 Cloud Storage |
|---|---|---|
| Public storage price | $6.99/TB/month until the scheduled July 1, 2026 increase | $6.95/TB/month |
| Upcoming public price change | $7.99/TB/month starting July 1, 2026 for affected Pay-Go and new accounts | No equivalent public price change found on the B2 pricing page at writing |
| Minimum monthly charge | 1 TB active storage minimum for Pay-Go object storage | First 10 GB free, then usage-based billing |
| Minimum storage duration | 90 days for Wasabi Pay as You Go | No minimum storage duration fee listed on the B2 pricing page |
| Egress policy | Free, but Wasabi says monthly egress greater than active storage is not a good fit and regular overuse can lead to limited or suspended service | Free up to 3x average monthly storage, then $0.01/GB |
| API request pricing | Free, subject to Wasabi's API request policy | Free Class A, B, and C calls. Class D is $0.004 per 10,000 after the first 2,500 per day |
For 50 TB of active backup storage, the storage-only math is boring:
- Wasabi at $6.99/TB is $349.50/month before taxes and optional services.
- Backblaze B2 at $6.95/TB is $347.50/month before taxes and optional services.
- Wasabi at $7.99/TB after the scheduled price increase is $399.50/month for affected accounts.
That difference matters at scale, but it is not the main MSP risk.
The main risk is quoting a backup service as if every month looks like storage-only math.
Restore behavior is where the comparison changes
Backup storage is bought for the bad day.
That bad day might be a ransomware restore, a failed server, a legal hold request, a botched retention policy, or a quarterly recovery test where the client finally asks how long payroll will be down.
The question is not just, "What does 50 TB cost to store?"
The better question is, "What happens when 50 TB needs to move?"
Scenario 1: normal month, 50 TB stored, 5 TB downloaded
This is the easy month.
Wasabi's free egress guidelines say a use case is a good fit when monthly egress is less than or equal to active storage volume. A 5 TB download month against 50 TB stored is inside that guideline.
Backblaze B2 includes free egress up to 3x average monthly storage. A 5 TB download month against 50 TB stored is also inside that included amount.
In this scenario, the choice comes down to minimum duration, retention behavior, immutability requirements, regional fit, support model, and whatever your backup software actually supports.
No drama. No great blog fight. Sorry.
Scenario 2: recovery month, 50 TB stored, 80 TB downloaded
Now the math gets useful.
With Backblaze B2, 50 TB of average monthly storage gives you up to 150 TB of included egress that month under the 3x policy. An 80 TB recovery month is still inside the included egress amount.
With Wasabi, 80 TB downloaded against 50 TB active storage exceeds the guideline Wasabi publishes for a good-fit free egress use case. Wasabi does not present that as a simple overage price on the FAQ page. It says use cases that exceed the guidelines on a regular basis may be limited or suspended.
That is not the same kind of risk.
Backblaze gives you a posted boundary and a posted overage rate. Wasabi gives you a policy boundary. If your MSP expects occasional large restore months, that policy needs to be in the client quote and in your internal runbook.
Scenario 3: ugly month, 50 TB stored, 180 TB downloaded
Backblaze B2 includes the first 150 TB of egress under the 3x policy. The remaining 30 TB would be billed at $0.01/GB.
Using binary TB math, 30 TB is 30,720 GB. At $0.01/GB, that is about $307.20 in egress overage.
That is not nothing.
But it is quoteable.
For Wasabi, the bigger issue is not a posted overage line. It is whether the use case still fits the policy and what happens if the pattern repeats. If the client is doing frequent full exports, repeated large restores, or backup validation that pulls more than active storage every month, you need to treat that as a design problem, not a storage discount.
Wasabi's 90-day minimum can be fine, unless your data churns
Wasabi's Pay as You Go FAQ says objects deleted before the 90-day minimum storage duration can create a Timed Deleted Storage charge for the remaining days.
For backup storage, that can be totally fine.
Many MSP backup workloads keep data longer than 90 days anyway. If the backup application writes durable restore points and retention is stable, the policy may not hurt.
But not all backup data behaves politely.
Short-lived fulls, test buckets, migration staging, rehydration work, backup copy jobs, and accidental overwrites can create churn. Wasabi's FAQ also notes that overwriting an object without versioning can transition the original object from active storage to deleted storage, which can trigger remaining minimum-duration charges.
Here is the rough MSP quote problem:
- You upload 10 TB for a migration or temporary backup copy.
- You delete it after 30 days.
- Under a 90-day minimum, you may still owe roughly 60 days of storage on deleted data.
- At $6.99/TB/month, that is about $139.80 of extra storage equivalent.
- At $7.99/TB/month, that is about $159.80.
The number is not catastrophic. The surprise is.
Backblaze B2's pricing page says it has no minimum storage duration fees. That makes B2 easier to reason about for temporary backup copies, short migration windows, and test data that gets created and deleted quickly.
Wasabi can still be the right answer for steady backup retention. Just do not sell it like deleted data instantly stops mattering.
Immutability is not a checkbox
Every MSP now knows to ask about immutable backup storage.
Good.
The next step is asking which kind.
Wasabi's immutability docs explain two different models: Compliance and Object Lock. They are mutually exclusive. Compliance is bucket-level. Object Lock applies to individual object versions and requires versioning. Wasabi also says Object Lock must be enabled when the bucket is created. You cannot enable Object Lock on an existing bucket later.
That matters if a client says, "Can we add immutability next month?"
Maybe. But not always on the bucket you already built.
Backblaze B2's Object Lock docs say Object Lock can be enabled when creating a bucket or on an existing bucket, but after Object Lock is enabled on a bucket, it cannot be disabled. B2 supports governance mode, compliance mode, legal hold, default bucket retention, and retention periods from one to 3,000 days. The same docs say there is no extra cost to use Object Lock, though normal storage charges still apply.
For MSPs, the product comparison is less important than the implementation rule:
Your backup quote should name the immutability mode, retention period, bucket setup requirement, and who is allowed to change it. If the quote only says "immutable backups included," it is not specific enough.
Also check your backup vendor.
Object Lock only helps if the backup application writes the right retention settings. Wasabi's docs specifically call out that third-party applications must support Object Lock when uploading objects. Backblaze says integrations like Veeam can enable that functionality behind the scenes.
Do not assume S3-compatible means your desired immutability workflow is automatically correct.
The restore bill is mostly labor
Storage vendors price storage.
MSPs sell recovery.
Those are not the same thing.
When a client has an actual restore event, someone has to coordinate the outage, confirm restore points, pull data, test application consistency, talk to the client, document the work, watch bandwidth, and decide when the restored environment is safe enough to hand back.
That labor does not appear on Wasabi's pricing page or Backblaze's pricing page.
It should appear in your quote.
At minimum, define:
| Restore assumption | Quote language to include |
|---|---|
| Routine file restore | Included or billed hourly, with expected response target |
| Quarterly restore test | Included cadence, success criteria, and what counts as a pass |
| Full server recovery | Covered labor hours, after-hours rules, and escalation owner |
| Mass data export | Whether storage egress, bandwidth, appliance shipping, and engineer time are included |
| Disaster recovery event | Who authorizes work, what is billable, and when emergency rates apply |
This is where cheap storage gets expensive.
Not because Wasabi or Backblaze did something sneaky. Because the MSP sold a recovery promise while pricing only the storage ingredient.
How to quote Wasabi vs Backblaze B2 without margin leakage
Use the same scoping questions for both vendors.
If the answers change the quote, they belong in the quote.
- How much active backup data exists today? Get this from the backup console, not from the client's memory.
- How fast is it growing? A 3 TB client growing 20% a year is a different account than a 3 TB client adding video archives every month.
- What is the retention policy? Daily, weekly, monthly, yearly, and compliance retention all hit storage differently.
- How much data is deleted or overwritten before 90 days? This is especially important if you are quoting Wasabi Pay as You Go.
- How often do you test restores? A restore test that downloads 100 GB is different from one that rehydrates an entire server set.
- What happens in a full recovery month? Model the largest plausible download, not the average month.
- Which immutability model is required? Bucket-level, object-level, governance mode, compliance mode, and legal hold are not interchangeable.
- Who pays for recovery labor? If the client thinks disaster recovery is included and you think only storage is included, congratulations on your future argument.
Scopable fits this because backup storage is not a SKU problem. It is a scoping problem.
Scopable gives MSPs a place to connect assessment findings, roadmap items, budgets, and quote language instead of burying restore assumptions in a spreadsheet. That is the difference between "we use Wasabi" and "this client has 22 TB, 12-month retention, quarterly restore tests, Object Lock requirements, and a recovery labor boundary."
The first sentence is a vendor preference.
The second is a sellable service.

When Wasabi is the better fit
Pick Wasabi when the backup pattern is steady and you can live inside the policy shape.
That usually means:
- Active storage is predictable.
- Monthly downloads usually stay at or below active storage.
- Retention is longer than 90 days, or churn is low enough that Timed Deleted Storage will not surprise you.
- You know whether the bucket needs Compliance or Object Lock before setup.
- Your backup application supports the immutability behavior you plan to sell.
Wasabi is easy to like when the workload matches the rules.
The mistake is treating "free egress" as unlimited recovery chaos and treating "cheap storage" as permission to ignore retention math.
When Backblaze B2 is the better fit
Pick Backblaze B2 when restore movement is harder to predict or temporary data is part of the workflow.
That usually means:
- You run larger restore tests.
- You want a published egress allowance tied to 3x average monthly storage.
- You want a posted egress overage rate after that included amount.
- You expect short-lived migration or test data.
- You do not want minimum storage duration fees in the quote model.
- You may need to enable Object Lock on an existing bucket.
Backblaze is not automatically better because it has a friendlier restore-month shape.
It still requires good scoping, client-specific retention design, and a real labor model. A posted egress policy does not write the recovery runbook for you.
Bottom line
Wasabi vs Backblaze B2 is not a question of which logo is cheaper this week.
For MSP backups, Wasabi is strongest when data is steady, retention is clear, and egress stays within its published guideline. Backblaze B2 is strongest when restore testing, export work, or disaster recovery might create larger download months and you want the egress math to be explicit.
The bad option is quoting either one from the storage price alone.
Before you sell the backup service, price the restore. Define the retention. Name the immutability mode. Model the biggest download month. Decide who pays for emergency labor.
If that still lives in a spreadsheet, join Scopable early access. Build the backup quote logic once, then stop rebuilding the same restore math every time a client asks for "cheap storage."
