This script uses the DNS powershell cmdlets available since Windows 2012. It exports the DNS zones hosted on a Microsoft DNS servers. First, a csv file is created (csv file called _-_domain_info.csv) with the following zone details:

• NotifyServers
• SecondaryServers
• AllowedDcForNsRecordsAutoCreation
• DistinguishedName
• IsAutoCreated
• IsDsIntegrated
• IsPaused
• IsReadOnly
• IsReverseLookupZone
• IsShutdown
• ZoneName
• ZoneType
• DirectoryPartitionName
• DynamicUpdate
• IsPluginEnabled
• IsSigned
• IsWinsEnabled
• Notify
• ReplicationScope
• SecureSecondaries
• ZoneFile
• PSComputerName

After that each zone is exported to a csv file with the following properties :

• DistinguishedName
• HostName
• RecordClass
• RecordData
• RecordType
• Timestamp
• TimeToLive
• PSComputerName

The cmdlet Set-DnsServerResourceRecord can be used to restore records by parsing the csv files

$domains = "domain.local" , "sub.domain.local"
$BkfFolderRootDom = "\\backup_server\share\backups\DNSbkp-"
$retention = 7
$date = Get-Date -format "yyyy-MM-dd"
$domain_info_output = "_-_domain_info.csv"

$domains | % {
	$ADdomain = $_
	$BkfFolderRoot = $BkfFolderRootDom + $ADdomain
	$BkfFolder = $BkfFolderRoot + "\" + $date
	
	if (-not(test-path $BkfFolderRoot)) {
		new-item $BkfFolderRoot -Type Directory | Out-Null
	}
	
	if (-not(test-path $BkfFolder)) {
		new-item $BkfFolder -Type Directory | Out-Null
	}
	
	Filter Select-FileAge {
		param($days)
		If ($_.creationtime -lt (Get-Date).AddDays($days * -1))
		{$_}
	}
	get-Childitem $BkfFolder -Directory | Select-FileAge $retention |Remove-Item -Force -Recurse
	
	$zones = Get-DnsServerZone -ComputerName $ADdomain
	$zones | export-Csv "$BkfFolder\$CSVZoneExport" -Delimiter ";" -NoClobber -NoTypeInformation
	
	$zones | % {
		$DNSZone = $_.ZoneName
		$CSVZoneExport = $DNSZone+".csv"
		Get-DnsServerResourceRecord -ZoneName $dnszone -ComputerName $ADdomain | export-Csv "$BkfFolder\$domain_info_output" -Delimiter ";" -NoClobber -NoTypeInformation
	}
}
