Veeam Backup & Replication 9.5 Update 4
User Guide for VMware vSphere

Backup Server

The backup server is a Windows-based physical or virtual machine on which Veeam Backup & Replication is installed. It is the core component in the backup infrastructure that fills the role of the “configuration and control center”. The backup server performs all types of administrative activities:

  • Coordinates backup, replication, recovery verification and restore tasks
  • Controls job scheduling and resource allocation
  • Is used to set up and manage backup infrastructure components as well as specify global settings for the backup infrastructure

In addition to its primary functions, a newly deployed backup server also performs the roles of the default backup proxy and the backup repository (it manages data handling and data storing tasks).

Protecting Backup Server

You can protect the backup server and save its configuration. Thus, in case the backup server gets corrupted or otherwise goes out of order, you can use the configuration backup to restore the backup server operation quickly. For more details, see Configuration Backup and Restore.

Backup Server Services and Components

The backup server uses the following services and components:

  • Veeam Backup & Replication Configuration Database stores data about the backup infrastructure, jobs, sessions and so on. The database instance can be located on a SQL Server installed either locally (on the same machine where the backup server is running) or remotely. For more information, see the following guidelines: Veeam Backup & Replication Best Practices.

Veeam Backup & Replication maintains the configuration database. Veeam Backup & Replication runs the DatabaseMaintenance system job once a week and when the Veeam Backup Service is restarted. The job updates the database internal statistics, defragments indexes and clears unused data. For details, see the Job.DatabaseMaintenance log file in the %ProgramData%\Veeam\Backup folder.

  • Veeam Backup & Replication Console provides the application user interface and allows user access to the application's functionality.
  • Veeam Backup PowerShell Snap-In is an extension for Microsoft Windows PowerShell 2.0 or later. Veeam Backup PowerShell adds a set of cmdlets to allow users to perform backup, replication and recovery tasks through the command-line interface of PowerShell or run custom scripts to fully automate operation of Veeam Backup & Replication.
