What CubeBackup is
CubeBackup provides self-hosted backup for Google Workspace and Microsoft 365, with data stored on-premises or in private cloud storage. Backups run automatically every hour, and incremental runs save only new or modified data. Unlimited versions support point-in-time restoration, including restores to another account or domain; the company says restores remain available after a subscription expires. Google Workspace coverage includes Gmail, Drive, Shared Drives, Contacts, Calendar, and Sites. Microsoft 365 coverage includes OneDrive, SharePoint, Teams, Outlook Mail, People, and Calendar. Backup destinations include local disk, NAS, Amazon S3, Google Cloud Storage, Azure Blob Storage, and S3-compatible services such as Backblaze B2 and Wasabi. Listed security measures include AES and RSA encryption, TLS 1.2 for data in transit, two-factor authentication for the console, and an immutable audit log. There is no free plan, but a 14-day trial is offered. Education / Non-profit costs $2 a year, and Business / Enterprise costs $5 a year; both are billed per user per year.
