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 Compatibility Matrix" for the earliest supported version of Windows Server before using WIB.
The Backup Client leverages off the 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 (see Microsoft's Technet article for further research).
Use a non-system volume
The dump destination cannot also be a system volume. When selecting the Dump destination drive letter, ensure that an additional volume is available where no system information is stored. (see Enabling Windows Image Backups below)
