Guest rosgiof@hotmail.it Posted June 20, 2008 Posted June 20, 2008 Hi all. I'm using Windows Ntbackup to backup my data (system state and office documents) on DLT and Ultrium (with windows 2000 server and windows server 2003) and all my test restores are always working perfectly. Today, browsing the Internet I found this article: http://www.windowsnetworking.com/articles_tutorials/New-Improved-NTBACKUP-Program.html where the author write: "My point is that NTBACKUP has never been completely reliable. You can use it to back up a system, but if you ever have to restore anything other than a few individual files, you never know what you are going to get." Do you agree with this article or do you think that windows ntbackup is a relaliable and professional solution? Thanks a lot to all, Rosgiof.
Guest Phillip Windell Posted June 20, 2008 Posted June 20, 2008 Re: Ntbackup I disagree that NT Backup is unrealiable. The article does not prove that NT Backup was the cause of the MOM Agent problem, he just assumes it. I actually went back to NT Backup because my BackupExec was too undependable and too overly complicated to deal with and fight with. NT Backup is simpler with less features,...but,...sometimes simpler *is* more dependable,...and what good are features that I don't care about and/or don't use to begin with? Even NT Backup has more features than really I need when you combine it with the Removeable Storage Service. NT Backup may not be "enough" for larger application requirements, but that does not make it "unreliable". He praises the Backup utility in Vista for having a simpler interface so we may seem to be agreeing there. I haven't worked with the Backup Utility in Vista, but the simpler interface he speaks of may be going too far to the extreme in the other direction from complex ones like BackupExec by being so simplified that the Admin or User doesn't have enough control over what is being backed up of how it is being backed up. I think many articles that are out there in Internet land need to be approached cautously. Most writers are not neutral an unbiased. Even when they are trying to be perfectly honest there is still a lot of personal opinions that creep into what they write. So you just have to read them and make you own judgement calls on them,...as I just did here. -- Phillip Windell http://www.wandtv.com The views expressed, are my own and not those of my employer, or Microsoft, or anyone else associated with me, including my cats. ----------------------------------------------------- <rosgiof@hotmail.it> wrote in message news:4d0651b9-cac4-4f94-aee2-6b4156a1fd7b@c58g2000hsc.googlegroups.com... > Hi all. > > I'm using Windows Ntbackup to backup my data (system state and office > documents) on DLT and Ultrium (with windows 2000 server and windows > server 2003) and all my test restores are always working perfectly. > > Today, browsing the Internet I found this article: > > http://www.windowsnetworking.com/articles_tutorials/New-Improved-NTBACKUP-Program.html > > where the author write: > > "My point is that NTBACKUP has never been completely reliable.

During my periodic tests I routinely recover folders of a few hundred MBytes with hundreds or thousands of files inside, without the slightest problem. When you use ntbackup.exe (or any other backup tool!) then it is mandatory to do three things: a) Perform a full recovery right at the beginning so that you know that you have configured it correctly. b) Check the backup reports on a regular basis, e.g. once a week for a server, preferably by emailing them to you by an automatic process. c) Perform a test recovery at regular intervals, e.g. twice a year. I suspect that the author of the article you quote ignored all three of these essential items, and paid the price.

Pegasus, I use ntbackup to save more than 30 Gb of data with almost 100.000 files. Also for all these data (and not only a few hundred Mb) is ntbackup reliable? Thanks again, Rosgiof.

I have to confess to not following that myself, particularly A and C. But the problem is how do I do that? If I do that on a live server and it fails then I just [possibly] trashed my server and have no backups because the backup I just made has just been proven to be a failure. But if I do the restore to other hardware I cannot use System State unless the hardware is identical, and we won't have the hardware because we were barely able to purchase what we have, let alone an identical "spare" set of everything. Now just doing files from file storage wouldn't be a problem and I could restore them to a different location as a test. Maybe all backup products (even NT Backup) should have a test mode where it goes through the motions of a Restore with fully reading the tape (verifying) but without actually writing them to the HD. Now, I do usually have NT Backup do a "verification" immediately after the backup :-),..of course my backups take twice as long because of it. -- Phillip Windell http://www.wandtv.com The views expressed, are my own and not those of my employer, or Microsoft, or anyone else associated with me, including my cats. -----------------------------------------------------

The test recovery I perform relates to data folders only, not to a system recovery. The target for this recovery can be anything: A spare partition on a server disk, or even a folder on some PC with a large disk. Remember - disks are cheap! About question a): IMHO the cost of a spare disk (or a spare RAID set) is trivial when compared to the cost of the downtime caused by a server that has to be rebuilt. My clients would not accept a line such as "I backed up your system every night but for some technical reason I am unable to restore the server. Please come back in two days and get off my back now!". In other words: I only sleep well if I KNOW that I can restore a system from backup. This implies that I must perform a full restoration, preferably right at the start when I have plenty of time and when there is no pressure. Backing up without a full test recovery may give me a warm feeling inside but it may leave me gulping for air when the crunch comes.

That's true. But non-technical executives often make the decisions. In my case I'd have to buy a complete identical server,..my arrays are internal, not external with the only exception being our video-out server that sends the broadcast to the air. I'd also have to buy one of each type I have here. We're a TV Station packed with various shades of hardware from one end of the building to the other, there's no way to buy enough spare hardware to cover everything. So I just have to depend on RAID Arrays not loosing the whole array and the few mirrored servers not losing both members. The rest will be hoping the Tapes do their job. My biggest fear is a building fire if we loose the building. Having good backups is a long way from putting the whole place back together. This discussion has got me thinking today just how much would be involved if such a thing happened. There is another TV Station in the next town that doesn't use their Studio except for storage,...which we might be able to "borrow" from them, but there is still an overwhelming amount of almost miracles that would have to happen to get the whole thing functioning again. -- Phillip Windell http://www.wandtv.com The views expressed, are my own and not those of my employer, or Microsoft, or anyone else associated with me, including my cats. -----------------------------------------------------

I totally agree with you, Pegasus, it's mandatory a test restore to be sure that all it's working well. I have 2 answer for you: - how do you test the system state restore with w2k3 srv? - and my last question that probably you haven't read in my last post: I use ntbackup to save more than 30 Gb of data with almost 100.000 files. Also for all these data (and not only a few hundred Mb) is ntbackup reliable? Thanks a lot for the help Bye, Rosgiof.

Here is a detailed tutorial on how to perform a system restore in case of a disaster: http://www.datamills.com/Tutorials/systemstate/tutorial.htm#How%20can%20I%20restore%20a I actually find this method too tedious, hence I use a disk imaging product such as Acronis True Image to create an imago of the system partition shortly after the initial installation. Restoration is then a two-step process: 1. Restore the image (which will take some 30 minutes) 2. Perform a System Restore as per http://support.microsoft.com/kb/240363. About backing up / restoring 100,000 files: I wouldn't because that's too many eggs in the one basket. When something goes wrong then you lose the lot. I would limit the number of files to 20,000 .. 30,000 per backup set. For the same reason I won't use multi-volume tapes (in fact I try to avoid tapes altogether).

I never thought about the problem you write (funny the eggs and basket comparison! :-), and actually I agree with you. So, please, help me another time again: I do my backups on 40 Gbytes (not compressed, 80 compressed) DLT HP cassette: 5 DLTs have one backup set of 20 Gbytes (around 50000 files), 5 DLTs have one backup set of 32 Gbytes (around 98000 files). If I do a backup (and write one backup set) on a DLT cassette, this backup overwrite the previous backup that was on that DLT cassette. My question: how could I divide my two backup sets using the same quantity of DLT (10) and follow your suggestion to divide the existing backup sets to more and small backup sets? And again: sorry, but I don't understand (I'm italian) what you mean with: "multi- volume tapes (in fact I try to avoid tapes altogether)" Maybe with "multi-volume tapes" do you mean "one big backup set on more than one DLT cassette" ? Thanks again very very much for your patience and your kind help. Bye bye, Rosgiof.

Here is what non-server versions say: /UM Finds the first available media, formats it, and uses it for the current backup operation. You must use the /P switch to designate a device-type media pool when you use the /UM switch so that Backup searches for the appropriate type of media (for example, 4mm DDS). When you use the /UM switch, Backup will search the following media pools for available media: Free pool, Import pool, Unrecognized pool, and Backup pool. When available media is found, the search will stop and the media will be formatted and used without prompting you for input. This command is not applicable to tape loaders and should only be used if you have a stand-alone tape device.
