Backup of DC - windows 2003Hi,
When I am taking a backup of a domain controller, should I also be backing up the windows folder? At the moment I am only taking a back of System State. thanks It is only my opinion,...but doing just the SS is a waist of time.
It is being dangerously presumptious about what will fail (or not fail) on the Server in a disaster. Do a whole Full Backup with SS. You can still selectively restore the SS only from the tape if that is ever needed. Keep in mind that a SS is worthless if it is a major Hardware Failure and you cannot replace it with identical hardware. This is really really bad if this is a DC and you don't run two DCs. Moral of the story,...tape backups are not a replacement for running two DCs. I would feel more protected with 2 DCs no tape backup,...but the only sensible thing is to run 2 or more DCs and do Full Tape Backups with SS as well. -- Show quoteHide quotePhillip Windell The views expressed, are my own and not those of my employer, or Microsoft, or anyone else associated with me, including my cats. ----------------------------------------------------- "biren" <bi***@discussions.microsoft.com> wrote in message news:F2BD26CD-9A3C-4CE9-9BFA-37CEC4A0881E@microsoft.com... > Hi, > > When I am taking a backup of a domain controller, should I also be backing > up the windows folder? > > At the moment I am only taking a back of System State. > > thanks Philip brings up two valid points (issue with restoring System State backup
to a different hardware and the need for redundancy - with at least two domain controllers per domain). I'd not however agree with his opinion regarding usefulness of the System State backup. While it is true that restoring it to a different hardware tends to be not only "challenging" but also not fully supported by Microsoft, this is typically required only in case of a domain-wide disaster. Otherwise (assuming that the same/identical hardware is not available), the common course of action is to simply perform AD cleanup and promote another domain controller as a replacement (providing, of course, that there exists another domain controller in the same domain). More importantly, System State plays crucial role in AD object restore - at least as long as you haven't migrated to Windows Server 2008 R2 envirnoment... hth Marcin Show quoteHide quote "biren" <bi***@discussions.microsoft.com> wrote in message news:F2BD26CD-9A3C-4CE9-9BFA-37CEC4A0881E@microsoft.com... > Hi, > > When I am taking a backup of a domain controller, should I also be backing > up the windows folder? > > At the moment I am only taking a back of System State. > > thanks I don't know what you disagree with,...sounds like we are in perfect

System State backup being a waste of time. I guess you were referring to the scenario where there is only a single domain controller in the domain - correct? cheers, Marcin Show quoteHide quote "Phillip Windell" <philwind***@hotmail.com> wrote in message news:%23s83f$n$JHA.4984@TK2MSFTNGP05.phx.gbl... >I don't know what you disagree with,...sounds like we are in perfect >agreement to me. > > > -- > Phillip Windell > > The views expressed, are my own and not those of my employer, or > Microsoft, > or anyone else associated with me, including my cats. > ----------------------------------------------------- > > > "Marcin" <marcin@community.nospam> wrote in message > news:uenU87n$JHA.4984@TK2MSFTNGP05.phx.gbl... >> Philip brings up two valid points (issue with restoring System State >> backup to a different hardware and the need for redundancy - with at >> least two domain controllers per domain).

Sometimes I also make my statements a little "extra" emphatic to get people to pay attention and maybe I give the wrong idea. -- Phillip Windell The views expressed, are my own and not those of my employer, or Microsoft, or anyone else associated with me, including my cats. ----------------------------------------------------- It finally, I hope windows folder doesnt require. Restoration will be
done when u have OS in the server only. So I hope we doesnt require
Windows folder, and SS is enough it seems. Am I correct?

Hello dileep.ponna,
As stated by Marcin and Philipp, better have the full server and the system state. But to answer your question, yes, a system state is the minimum you need to restore a DC. But this has limitations as already explained.

I have read this thread and now I am confused! WE do have two domain controllers in the same physical location. All the servers are windows 2003. Let us say, we had a fire and everything got burnt. Am i able to recreate the domain based on System State backup alone? I would reinstall windows 2003 (on a new server, presumably), and then restore SS based on the backup. In this case do I need c:\Windows folder to be backed up? Why do I need the whole of C:\ when its just a pure domain controller? Thanks for your input. Hope this clarifies the picture. You ...need...the..whole...thing.
What good is the Windows folder without the rest of the drive's contents? You don't want to restore a Registry full of Application Settings for Applications that no longer exist on the machine becuase you didn't install them along with it (ex. C:\Program Files\*) Full Backup,...*everything* on the drive,...plus the System State It needs to be the exact same identical hardware,...or at least the same model of Drive Controllers,...of the thing will "blue screen" on you when you try to start it up. If you get really, really, really, really lucky it might boot from different hardware,...but it is a "crap shoot",...and as someone already said,...MS does not support restores to "different hardware". To protect from a fire keep the two DCs in different buildings (or far far away from each other if it is a very large building) so you won't lose both at the same time in the same fire. 90% of your ability to recover from a disaster comes from *not* loosing both DCs at the same time. The primary purpose, as far as I am concerned, of the Tape Backups is to protect against *software disasters* when the hardware is still intact. -- Show quoteHide quotePhillip Windell The views expressed, are my own and not those of my employer, or Microsoft, or anyone else associated with me, including my cats. ----------------------------------------------------- "biren" <bi***@discussions.microsoft.com> wrote in message news:4004B217-4AAF-41C8-AAA6-6D23D1F64FC3@microsoft.com... > Hi, > > I have read this thread and now I am confused! > > WE do have two domain controllers in the same physical location.

We are also looking at how we might relocate one DC so that I wouldn't loose both in a fire, but we haven't gotten that done just yet. -- Phillip Windell The views expressed, are my own and not those of my employer, or Microsoft, or anyone else associated with me, including my cats. ----------------------------------------------------- |
