The essential guide to Exchange Server backup and recovery

Administrators should carefully craft Office 365 and Exchange Server backup plans to mitigate any issues and keep data secured during the backup process.


Email is a critical component of any organization, and securing and backing up email files and data in case of a disaster should take utmost importance. Administrators tasked with backing up Exchange Server must familiarize themselves with what data exists where and what to do to protect that data.

This guide walks Exchange administrators through the challenges associated with an Exchange Server backup, and Office 365 or hybrid messaging administrators through Office 365 backup. It also covers native and third-party tools that can ease the process.

Exchange and Office 365 gotchas

Backing up Exchange Server and Office 365 data comes with unique challenges.
