Veeam Backup for Microsoft Office 365
User Guide

Understanding Repository Files

After you install Veeam Backup for Microsoft Office 365, Veeam creates a default backup repository which is the C:\VeeamRepository directory on the localhost. Backup repositories are used to store organization backups created with Veeam Backup for Office 365.

You can configure additional repositories associated with different backup proxies. Direct Access Storage is a recommended type for storing your backup data; others are SAN and SMB3 (with experimental support).

The structure of the repository directory consists of subfolders that are organized and named based on the last modification time of items that are being backed up. 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.

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.
