BE 2012 backing up system state and system files on domain controller
I have a question about the system state and system files.
We have two domain controller and backing up system status on both computers.
On domain controller 1 the backup size is about 1GB and on domain controller 2 about 21GB.
I found out that system files on DC1 are a few hundred megabytes and on DC2 the system files are about 20 gigabytes!
Now my question: What are these system files?
Where can I find them?
