Frequently asked questions
How does the backup storage work?
It converts computers or servers, gigabytes per endpoint, and version retention factor into a planning class using a published rule. Multiply endpoints by gigabytes each and a version-retention factor. The headline is a class such as 500 gb, 2 tb, 5 tb, and 10 tb, not a vendor ranking.
Is Backblaze B2 + Computer Backup better than IDrive 5 TB?
This page does not rank Backblaze B2 + Computer Backup, IDrive 5 TB, and pCloud 2 TB. Backblaze B2 + Computer Backup and IDrive 5 TB are listed because they are real products with official pages that map to different or overlapping classes. The useful question is which class matches your inputs.
