Veeam Backup for Microsoft Office 365
User Guide

Repository Files

Default backup repository is created after finishing the Veeam Backup for Microsoft Office 365 setup and can be found in the C:\VeeamRepository directory on Veeam Backup for Microsoft Office 365 server. This repository is associated with the default backup proxy that is running on Veeam Backup for Microsoft Office 365 server. You can configure additional repositories associated with the backup proxies, pointing them to the local folders or shared folders. Direct Access Storage is a recommended storage type; others are SAN and SMB3 (with experimental support).

During the initial backup job, Veeam creates the backup of the mail datastore with the corresponding structure, including ADB database file, logs, and checkpoint files in the appropriate subfolder on a target repository. All subfolders in the repository are organized and named based on the last mail item modification time. For example, an item that was last modified on 26 May 2015 will be backed up to the subfolder named 2015, all items last modified in 2016 – to the 2016 subfolder and so on.

Repository Files 

Repository.xml file stores configuration settings, including proxy and management server IDs. Inside the repository subfolders you can find the following files:

  • The repository.adb file, which is the database file that keeps the data of the Exchange Organization mailboxes such as mailbox folders, subfolders, and items. Such data is kept according to the retention policy. See the Configuring Retention Policy section.
  • Checkpoint and transaction logs are required for log replay when bringing the database to a specific state.
