Guides/Microsoft 365 backup
Microsoft runs Microsoft 365. Your data is yours to protect.
Under Microsoft's shared responsibility model, Microsoft is responsible for the service: its infrastructure, availability and resilience. Your organization is responsible for its data and accounts: recovering from deletions, ransomware and bad changes, and keeping data as long as you need it.
Who protects what
Where the service ends and your data begins.
| Risk | Who owns it | What KELYN and Commvault add |
|---|---|---|
| Service infrastructure and uptime | Microsoft runs it | Microsoft 365 keeps its full functionality; backup is added alongside it. |
| Accidental or malicious deletion | Yours to recover | Point-in-time recovery of Microsoft 365 data to an earlier point. |
| Ransomware and compromised accounts | Yours to recover | Immutable copies in isolated storage outside your tenant, to recover from after an attack. |
| An outage or data loss inside Microsoft 365 | Yours to plan for | Backups sit outside the tenant, so they aren't lost with it. Multi-cloud replication keeps data available. |
| Long-term retention and compliance | Yours to define | Long-term retention options and regulatory compliance support. |
| Mailbox storage limits | Yours to manage | Archiving moves email to cost-effective storage, within Exchange Online limits. |
| Finding archived content | Yours to manage | Content indexing with fast search, for admins and end users. |
Check your setup
Eight questions to ask about your Microsoft 365 backup.
- 01
Are your backup copies stored outside your Microsoft 365 tenant?
- 02
Are those copies immutable, so ransomware or a compromised admin can't change them?
- 03
Can you restore to a point in time: one mailbox item, one file, one Teams channel?
- 04
How long do you keep backups, and does that meet your retention and compliance requirements?
- 05
Who monitors backup jobs every day, and who runs the restore when you need one?
- 06
When did you last test a restore, and how long did it take?
- 07
Are Entra ID users, groups and policies protected too? Nobody signs in to Microsoft 365 without them.
- 08
Do you know how close your mailboxes are to Exchange Online storage limits?
