Hi,
We have Windows Server 2012 R2 Server. This server contains Active Directory, DNS and Exchange Server 2010. We are taking a daily backup of System State using "Windows Server Backup". Sometimes the backup size for System State backup is appr. 12GB, while sometimes it reduces to 500MB or less. Why is this huge difference. Is there something we are missing in System State Backup? I'm always selecting VSS Full Backup.
