Why Your Cloud Business Data Needs Its Own Backup

A common assumption: "Our email and files are in the cloud, so they're already backed up."

It's an understandable belief, and a risky one.

The shared responsibility model

Cloud providers operate on a shared responsibility model. Your provider is responsible for keeping the service available, including its infrastructure, uptime and physical security. You remain responsible for your data: who can access it, what gets deleted, and whether you can get it back.

Built-in recycle bins and retention features help with simple mistakes, but they are not a substitute for an independent backup. They have time limits, and they can be bypassed by the very events you most need protection from.

Where businesses actually lose data

• Accidental deletion. A departing employee, or someone cleaning up a shared folder, removes something important.
• Malicious deletion. A disgruntled insider or an attacker with a stolen login deliberately wipes mail or files.
• Ransomware and sync. Encrypted files synchronise to the cloud and overwrite good copies.
• Retention gaps. A deleted item sits past its retention window before anyone realises it's missing.
• Configuration mistakes. A policy change quietly removes content.

What a proper backup looks like

1. Independent. Stored separately from your main cloud account, so a compromised account can't touch it.
2. Complete. Covers mail, calendars and contacts, shared files, team sites and chat.
3. Immutable. Written so that nobody, including attackers, can alter or delete it during the retention period.
4. Encrypted. Protected in transit and at rest.
5. Tested. A backup you've never restored is a hope, not a plan. Regular restore tests prove it works.

The business test

Ask yourself: If every mailbox and shared drive disappeared tonight, how long until we were operating normally again? If the answer is "I'm not sure," that's your gap.
