Veeam Backup for Microsoft Office 365 2.0
User Guide

Understanding Repository Files

Backup repositories are used to store your backup data archived with Veeam Backup for Office 365.

After you install the solution, Veeam creates the default backup repository which is the C:\VeeamRepository directory on your localhost. You are encouraged to configure additional repositories to enhance overall production environment performance.

Direct Access Storage is a recommended type for storing your backup data. Others are SAN and SMB3 (with experimental support). For more information on configuring new backup repositories, see Configuring Backup Repositories.

The repository structure consists of various subfolders that are organized and named based on the last items modification time. For example, an item that was last modified on 26 May 2015 will be backed up to the subfolder 2015, all items last modified in 2016 to the subfolder 2016 and so on.

When you run a backup job for the first time, Veeam creates the following set of files:

  • The Repository.xml file that stores overall configuration settings, including proxy and management servers IDs.
  • The repository.adb file, which is the database file that keeps your Office 365 organizations data. Such data is kept according to the retention policy. For details, see Understanding Retention Policy.
  • Checkpoint and transaction logs that are required when performing log replay to apply the specific state when recovering your databases.

Repository Files

Understanding Repository Files Note:

If you map several backup jobs to the same backup repository, the backup data will be merged into a single repository.adb files.
