FAQ
Common questions about choosing Carbonio
Can I migrate from Microsoft 365, Google Workspace, Exchange, Zimbra, Open-Xchange, or Zoho?
Yes. Certified partners deliver migrations from all major platforms such as Microsoft 365, Google Workspace, Exchange (Server and Online), Zimbra, Open-Xchange, and Zoho. Mail, calendars, and contacts move across; the exact fidelity depends on what each source platform exposes, which the partner confirms during scoping.
How long does a typical migration take?
A Carbonio migration's timeline depends on user count, mailbox size, and the source platform. The technical migration can run in days for a small organization; the full partner-led project — planning, training, and cutover — typically runs 4–5 weeks for small deployments up to 14–18 weeks for the largest or those needing a coexistence period. A certified partner scopes the exact timeline.
Will users notice disruption during the switch?
Migrations are usually planned for minimal disruption — coexistence periods, phased rollouts, and weekend cutovers are standard. The partner designs the rollout around your timing and risk tolerance.
Is Carbonio cheaper than Microsoft 365, Google Workspace, or Zoho?
Total cost of ownership depends on deployment model, user count, and add-ons. Three things typically move the math in Carbonio's favor: a unified platform replaces multiple subscriptions (mail + chat + meetings + files + backup), self-hosted deployments avoid public-cloud per-user markup, and built-in capabilities (real-time backup, antivirus, antispam, HSM) remove third-party tools and extra-cost add-ons like EOP or Vault. A partner can build a TCO comparison for your specific setup.
What does "real-time backup, built-in" actually mean?
Every mailbox transaction (sent, received, moved, deleted, labelled) is captured continuously, not on a nightly schedule. From the admin panel, you can restore an individual message, folder, or full account from any point in time without third-party tooling. The backup runs coherency checks, supports restore on a different node (self-coherent backup), and is infrastructure- and version-agnostic — the recovered data isn't tied to the original topology or Carbonio version. Note: real-time backup covers mailbox transactions; Files, Chats, and external SMTP follow separate recovery paths.
Can I run Carbonio in hybrid mode (on-prem and cloud)?
Yes. Carbonio is built as installable components communicating over Carbonio Mesh, so parts of the deployment can sit on-premises and others in private cloud — including dual-region and DR-paired topologies. Same platform, same admin panel. That's the difference from public-cloud-only suites like Microsoft 365, Google Workspace, and Zoho — where you take their cloud or nothing — and from Exchange, where on-prem and Online don't operate as one unified platform.
What happens to my data if I move to Carbonio?
Your data stays on infrastructure you control, in the jurisdictions you choose. Carbonio is built on open standards and common protocols (IMAP, SMTP, CalDAV, CardDAV, SAML, LDAP, S3-compatible storage), so you can move data, change clients, and audit the stack — choices closed proprietary cloud-only platforms don't give you.
Carbonio is the best option for your sovereign collaboration needs
