The backup policy would define the backup approach, tool, frequency, backup location and many other important points. There are many third party tools available in the market for backing up and restoring Active Directory. We strongly recommend the daily backup. In an enterprise environment where data changes in every second, restoring an old backup does not make sense.
Please note that in a multi domain forest, every Domain needs to be backed up separately. This is because there are few partitions which are different for every Domain, like Domain Partition and DomainDnsZone partition. Microsoft recommends to take backup of at least two Domain Controllers for each Domain , and one of those two Domain Controllers should be the Operation Master role holder. This is to avoid any future RID block conflict. Do not store the backup in a network share.
Backup versioning and automatic space management which we will cover in next section will not work through a network share. Always store the backup in a local, non-system volume which is dedicated for storing backup. The local disk can be mounted from SAN or in case of VM can come from a datastore, but it has to be mounted in such a way that it is displayed as a locally mounted disk in the Disk Management tool.
As mentioned before, we will not store anything else on that volume. Windows Server Backup stores backup versions in volume shadow copies. This shadow copy retains the Point in time state of the Storage volume where the backup is stored, and each Point in Time State is called a Backup Version. There will be no separate folder for each backup, instead, there will be versioning for each instance of backup.
Every time the backup job is triggered manually or through scheduled task , a new version is created along with a unique snapshot ID and timestamp. If you do not specify this parameter, system state recovery is performed for the actual computer, which needs a restart at the end of the operation. ADIFM recovery requires this parameter.

You must run Wbadmin. To perform system state backup, you can input the following Wbadmin system state backup command syntax:. In this command, X should be replaced with the drive letter of the partition to store the system state backup image.
The -quiet parameter is not generally needed, but if you don't want to be prompted to enter the letter Y to confirm this operation before the backup starts, make sure this parameter included. For example, to backup system state to E: drive, you can use the following command:. Microsoft Scripting Guy, Ed Wilson, is here. Things are really becoming exciting around here. I will later announce a time when they will be at the Scripting Guys booth, so if you are in Orlando at TechEd , make sure that you can stop by.
This is not all— I will make sure to announce any other cool things we come up with. Note This is the second blog in a series of Hey, Scripting Guy! Blogs that discuss using the Registry provider. For additional information about working with the registry via Windows PowerShell, see this collection of blogs. One of the easiest ways to ensure system reliability is to create a restore point prior to making potentially damaging changes.
In this way, if a problem arises, it is rather simple to roll back the changes. These cmdlets require administrator rights due to access to protected registry keys and other vital configuration files. Keep in mind that these cmdlets only work on client systems later than Windows XP. These cmdlets do not work on server versions of the operating system. There are several cmdlets that you can use to work with system restore. These cmdlets and their associated descriptions are listed here.
Note The following command retrieved the information in the previous table:.
