With Windows Image Backup (WIB) enabled, all the critical volumes on a Windows machine will be backed up (a volume being a single accessible storage area resident on one or more partitions of one or more physical disks). These volumes contain the operating system and other system-critical data for the operating system to function properly (also known as "system" volumes).
Note: Please refer to the System Requirements and Compatibility Matrix for the earliest supported version of Windows Server before using WIB.
How it works
The Agent leverages Windows Server Backup technology. WIB implements the command-line usage of WSB’s “wbadmin” command with the "systemstatebackup" or "–allCritical" parameters set in order to perform system-state-only or critical volume backups. When the backup occurs, all files necessary files are temporarily stored in consolidated format in a central "dump" destination i.e. a "WindowsImageBackup" folder on the same machine, before being transferred to the Storage Platform. Because of this, when the backup is transferred to the Storage Platform, no deduplication is performed.
Note: Windows Server Backup does not back up or recover registry user hives (HKEY_CURRENT_USER) as part of system state backup or system state recovery.
