Exchange Online Backup

Recommended Posts

Hi, @darkhorse!

There are several points you have to take into account while backing up your Exchange Online. Ensure you think of the following aspects:

1. Define what has to be protected
Microsoft 365 offers built-in data protection. However, Microsoft isn't legally responsible for data protection. That's why you might need a backup solution to fulfill all of the required processes.

Microsoft uses retention policies to store or delete data. You get three data retention options:

  • Retain only. Store your data for a specific time
  • Delete only. Delete data after a specified time
  • Retain and delete after. First, store data for the needed time and then delete it

2. Set your RTOs and RPOs
Before building your Exchange Online backup strategy, set clear Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs).

3. Run incremental backups regularly
Incremental backups are perfect for Exchange Online emails as they copy only the new data since the previous backup. As a result, incremental backups save your storage space.

4. Define your backup rotation scheme
You need to keep in mind the type of your backup, the required storage and the storage media you require. Those are the basic factors that define your backup process. To back up your Exchange Online, you can use a Grandfather, Father, Son (GFS) rotation scheme, which means:

  • Grandfather: your full monthly backup
  • Father: your full weekly backup
  • Son: your daily incremental backup

5. Keep your data on-premises
Keeping your backup destinations diverse is one of the best ways to ensure data protection and business continuity. Having an on-premise copy helps you recover your data promptly if something happens with the copy stored offsite.

6. Automated backups
Manual backups require a lot of time. That's why scheduled and automated backups are great to avoid network congestion and save your time. 

7. Secure backup access
Use role-based access control (RBAC) and multi-factor authentication (MFA) to protect your backups from unauthorized access.

8. Granular recovery
This feature is helpful for the instant recovery of your Exchange Online data. You can quickly recover separate emails without running a full recovery. 

9. Compliance requirements
According to the law, some data has to be kept for legal compliance. Regular backups can help you have all relevant data available, while advanced search features allow you to find the data you require promptly.
