Backup up DNS RRS feed

  • Question

  • Hello,

    We had an issue last night where an admin added another DC to our domain and changed some setting in DNS and basically cleared all our DNS records so most of our systems went down (Skype, email etc).  What was weird the DC he was on had a good DNS with all the records and rebooting it after many hours caused it replicate again to the other DCs and all was ok.

    We thought about restoring AD which didn't sound good to me.

    Is there are an easy way I can keep regular backups of all our DNS zones? and restore?

    Thanks

  • Hi Tb,

    Please run dnsmgmt.msc to bakeup DNS zone file.

    Here is information about how to backup zone file for your reference:

  • You have several options to backup your DNS zones:

    1. The easiest one is to create a backup of Active Directory Domain Services (assuming you use AD-integrated DNS-zones). Later on you restore DNS zones/records objects from this backup as you'd do with any other AD object. See more about the restoration here: https://technet.microsoft.com/en-us/library/cc816878(v=ws.10).aspx

    This is the preferred way.

    2. For file-based zones you may use the method which John suggested.

    3. For both file-based and AD-integrated zones you may utilize Get-DnsServerZone and Get-DnsServerResourceRecord cmdlets: write a script which will export all vital data about your zones and records and later import those which were damaged using Set-*/New-* cmdlets of DnsServer module.
