Editorial assessmentBoth back up computers to the cloud automatically, encrypt data with an optional private key, and let admins manage users from a web console. They differ in how they charge and in what else they back up.
Backblaze charges the same $99 a year for every computer, however much data it holds, including attached external drives. IDrive Team sells bundles (5, 10, 25 computers and up) with storage that grows with the bundle, and IDrive Business charges by storage with no limit on computers. Storage matters as much as computer count: Backblaze has no storage cap per computer, IDrive Team scales storage with the bundle (5 TB for 5 computers), IDrive Business is priced by storage, and Carbonite Core includes 250 GB for the whole account.
Backblaze Computer Backup covers Mac and Windows computers only; for servers and NAS it points to its separate B2 Cloud Storage product. IDrive Business includes server backup (SQL, Exchange, Hyper-V, VMware), IDrive supports Linux and NAS devices, and it sells Microsoft 365, Google Workspace, Salesforce, Dropbox and Box backup as an add-on.
Backup history does not move between services: none of the three imports another’s backups, so a switch means a fresh first backup on the new service while the old one keeps your version history until you cancel.
Standard list prices checked September 19, 2026, annual billing unless marked. IDrive Team bundles include 5 TB per 5 computers and charge $0.50/GB/mo above that; IDrive Business is priced by storage. Promotional first-year discounts, add-ons and taxes are not included.
You back up Mac and Windows computers that hold a lot of data and want one flat price per computer with no storage limit.
You also need to back up servers, NAS or Microsoft 365 and Google Workspace, or you want the lowest price for a small team with modest data.
Uses your selections above. Estimate excludes add-ons, overages, and negotiated discounts.
Backblaze offers a 15-day trial and IDrive a free 10 GB plan. Back up one computer on each and time a test restore before you commit.
