Looking after your files

Microsoft 365 backup, explained.

Microsoft 365 includes recovery features. A backup plan answers a different question: what can your business restore, from when, and with whose help?

Sync, retention and backup do different jobs.

Sync keeps information current across locations. That is convenient when you work on more than one device, but it also means changes can travel. Seeing a file in two places is not enough to establish a recovery plan.

Retention rules, version history and recycle bins can help in different situations. Backup is another layer with its own protected workloads, recovery points and limits. The useful question is not whether the cloud is good or bad. It is which recovery option fits the problem you need to solve.

Understand the recovery you already have.

Microsoft documents options to recover OneDrive files, including previous versions and deleted items where available. Those options have conditions and limits. Microsoft also offers a separate Microsoft 365 Backup service for supported Exchange Online, OneDrive and SharePoint workloads.

That does not mean every Microsoft 365 subscription already includes every backup capability, or that every application is covered. Your licenses, configuration and chosen backup service matter. Ask your provider to explain what is active in your environment rather than relying on a general claim that everything is in the cloud.

Put names against the important information.

Start with the places your team works: individual mailboxes, shared mailboxes, personal work files and shared sites. Then identify which of those are included in the proposed backup. Ask about anything outside that list, including other business applications.

Teams brings several services together, so a promise to back up Teams needs detail. Clarify the files, messages and other content actually covered by the selected service. Treat a computer backup and a Microsoft 365 backup as separate scopes unless your agreement explicitly says otherwise.

  • Which accounts, sites and content are included?
  • How far back can we recover, and under what limits?
  • What happens to coverage when someone joins or leaves?
  • Who requests, approves and performs a restore?
  • Is recovery assistance included or separately billed?
  • Is restore testing included, and what evidence is provided?

Plan for people leaving, too.

Before removing a departing employee’s account or license, decide who needs the mailbox and files and how they should be preserved. Access removal and information preservation need to be coordinated. They are related tasks, but they are not the same task.

Tell your provider about planned departures early when possible. Agree who authorizes the change and what should remain available to the business. Avoid assuming that an old account will keep its information indefinitely after a subscription change.

Make the recovery responsibilities clear.

A backup subscription and a complete recovery service are not interchangeable. Confirm who monitors the service, who handles failed jobs and what help you receive when information needs restoring. Recovery time depends on the incident, amount of information and services involved.

DeltaBind can review your Microsoft 365 needs and quote the agreed coverage. Protected workloads, retention and recovery work must be confirmed in that scope. Scheduled restore testing is separate from recurring care and backup services. If you need a documented recovery exercise, raise it before accepting a quote so we can discuss separate work.
