DNS, DHCP Backup recovery Bat (batch automatically implemented) _ Server other

Now the server running a lot of system services, although there is no problem in the middle, but still afraid, if there is a problem, is a few days of time no, tired of 4 of people things AH. So you have to backup everything. Ghost Backup is the system, but the service configuration is at any time in the change, can not always come to a ghost bar, say no display, very troublesome.
Studied for an afternoon and finally implemented automatic DNS and DHCP backups.

Backup of DNS

1. Stop DNS Service
2, open regedit, find Hklm\system\currentcontrolset\services\dns
3. Export this branch of DNS. Named DNS-1
4, find HKLM\Software\Microsoft\Windows NT\CurrentVersion\DNS server
5, the DNSServer branch export, named DNS-2
6, open \windows\system32\dns, all of which *.dns files copied out, and Dns-1.reg and Dns-2.reg saved together.
Back up the above content.

DNS recovery:

1, when the DNS server in the zone fails, re-establish a win2003 server, and the DNS server to be replaced by the same name, set the same DNS suffix and IP address.
2. Install and start the DNS service in the new system.
3. Copy the *.dns file from the previous backup to the \windows\system32\dns folder of the new system.
4, disable the DNS service.
5, the backup of the Dns-1.reg and Dns-2.reg import into the registry.
6, restart the DNS service.

Fast Backup of DHCP
Command line:
netsh dhcp server dump >dhcp_bak.txt
Backup completed.
If the original DHCP server is corrupted, you need to create a new DHCP server and copy the Dhcp-bak.txt.
To run at the command line:
Netsh exec dhcp_bak.txt
In this way, the relevant information is restored, but the lease information cannot be recovered in this way.

This is only a manual implementation of the method, as a server, this is not enough, every day to backup not only trouble also very not insurance (forget how to do?) , so we can do a batch, and then set up a task to automate the implementation of the backup.
The following is the code for the backup:

@echo Backup DNS config start

@echo DNS config backup complete!
@echo backup DHCP config start ...

netsh dhcp server dump >d:\backup\dhcp\dhcp_bak.txt/y
echo DHCP config backup complete!
echo off
exit

Save the above code as a bat file, and double-click to run the DNS and DHCP backup automatically.

This involves the export and import issues of the Registry
Export:
regedit/e filename Path
When the space occurs, enclose the entire path in quotes, or it will not recognize the space in DOS.

Import:
At the beginning of the regedit/s command, it seems no use, so use the reg import command, under Windows 2003 pass the test!
