Cloud backup for small business
01

Sync is not backup

OneDrive and SharePoint sync copies changes in real time — including ransomware encryption and accidental mass deletes. Backup means point-in-time copies you can restore from, often held separately with retention policies and admin-only delete rights.

02

What to protect

Cover Microsoft 365 mailboxes, OneDrive, SharePoint, Teams metadata where required, plus any on-prem servers or NAS still in use. Line-of-business databases and accounting files need agent-based backup if they do not live natively in M365.

03

Choosing an approach

Microsoft 365 retention and recycle bins help short-term mistakes but are not a full disaster recovery strategy. Third-party cloud backup or hybrid appliances add longer retention, cross-tenant restore options, and reporting leadership can audit.

04

Test restores quarterly

Schedule a restore test of a mailbox, a SharePoint library, and one critical server file set. Log time to recover and who performed it. Untested backup is a hope — not a plan.

Common questions

Does Microsoft 365 include backup?

Microsoft 365 has retention and recycle bins, but that is not a full backup strategy — use separate cloud backup and test restores. See mrtechmelbourne.com/guides/cloud-backup-small-business
