What is BRR (Bare Metal Restore) in Windows Server?

BRR stands for "Bare Metal Restore". It is a feature in Windows Server that allows you to restore a server to its original state, including the operating system and all installed applications, using a bare metal image. This means that the entire server, including the hard drive, is wiped clean and restored to its original state, rather than just installing a new copy of the operating system over the existing one.

BRR is useful in situations where you need to completely reset a server, such as when you are troubleshooting issues or when you want to ensure that all software is up-to-date and properly configured. It can also be used to quickly deploy new servers with a consistent configuration, as well as to migrate servers to new hardware or to a different version of Windows.

To use BRR, you will need to have a bare metal image of the server's hard drive, which can be created using tools such as Windows Server Backup or Microsoft System Center Configuration Manager. Once you have the bare metal image, you can use the BRR feature in Windows Server to restore the server to its original state.
