Legacy Exchange backup and purge options

Use this short-cut to specify backup preferences for system state data and to configure purge options. The System State Backup Configuration section provides the opportunity to specify whether the system state data is included with the master or differential backup. This option is enabled only if Active Directory is installed on the Microsoft Exchange server workstation. System state data contains most of the elements of a system’s configuration, but it might not include all of the information that is required to recover a system from a failure. System state data can only be restored on a local computer and requires the system to be in Directory Services Restore mode. The system state data of a remote computer cannot be restored.

Note: Do not perform a system state backup when performing an Exchange 2007 information store backup on a Windows Server 2008 or 2012 system.

The Purge Configuration section of the interface allows you to specify the number of master and differential backups that should be maintained before backup purging is initiated.

The Use Hostname option sets the name of the directory where Exchange information store backups are kept within the samba share on the backup system.
