Does Microsoft 365 automatically back up my data?

No, and this is one of the most common and costly misconceptions. Microsoft operates on a shared-responsibility model: they keep the service running and protect the infrastructure, but safeguarding your data is your responsibility. Default retention for deleted items is only 14 to 30 days, and Microsoft explicitly recommends third-party backup. G6 implements enterprise-grade backup and retention policies so your data is protected even if files are accidentally deleted, an account is compromised or ransomware encrypts your environment.
