Pick Backblaze B2 if
- Fits if you have developers or an IT person to point backup tools at an S3 bucket
- Works for teams storing terabytes of backups that rarely get read back

- Watch out: API calls past the first 2,500 a day cost $0.004 per 10,000 on Class D transactions
- Watch out: B2 Overdrive is $15 per TB and up, with a multi-petabyte commitment bought by quote
Pick Zoolz if
- Fits if you have several terabytes of archives, such as photos or video, that you almost never open
- Makes sense if a small team wants one backup bill for up to 5 users

- Watch out: the 30% yearly discount is shown with no end date, and only monthly and yearly billing are offered
How we grade them
| 2.0GPABackblaze B2Fair | 2.0GPAZoolzFair | |
|---|---|---|
| Value for money | C$6.95 per TB a month matches the category's middle price. This is a different kind of product from consumer storage, billed by the terabyte. | C$7.99 a month for 2.5 TB, or $79.99 a year, against a $6.95 middle in file storage. Per terabyte it is low, but the starting price for one person is a little above the middle. |
| Free plan and trial | CThe first 10 GB is always free, with free egress up to 3 times what you store, and you'll pass 10 GB quickly. | CA 14-day trial with no credit card, and no free plan. After two weeks you pay. |
| Features | CStorage through an S3-compatible API with lifecycle and partner integrations, but the page shows no consumer sync app. It does its narrow job fully. | CBackup with versions, incremental uploads, a local copy for faster restores and time-limited share links. The listing's own gap: only the small hot tier is for quick access, so it is a backup service and not a daily-use drive. |
| Ease of use | DIt needs an API, keys and tooling, so it's a developer service. No store rating on record. | CNo store rating on record. You install the backup program and pick what to protect, which is ordinary setup for a backup tool. |
| Platforms and integrations | BThe vendor lists 8 integrations and an S3 API, but it is web only, with no apps. | CWindows and Mac programs plus a browser view. One family of devices: no phone apps and no Linux. |
| Best for | cheap object storage for developers and IT teams | backing up big archives that you rarely open |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
