I am finished with the Q&A Log from Part 19 (Introduction to Disaster Recovery) of the 24 Part Exchange 2007 Webcast series.  Please let me know if you have any questions.

Exchange Server 2007 Webcast Series (Part 19 of 24) Questions and Answers Log (03-26-07)


Question: When SP1 will be launched?

Answer: Not until later this calendar year.


Question: I had missed 18th hour of the 24hours... Do you have a link to download it?

Answer: http://msevents.microsoft.com/CUI/EventDetail.aspx?EventID=1032323563&Culture=en-US.


Question: Is PFMIGRATE.WSF still supported to perform Public Folder migrations from 2003 to 2007?

Answer: No - but check out http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=980440&SiteID=17.  We do plan to provide an update though.


Question: Is AirSync a Microsoft proprietary protocol or are the spec's for AirSync published?

Answer: this article can provide more information for you. http://www.microsoft.com/technet/solutionaccelerators/mobile/deploy/msfp_c.mspx.  It is a protocol that Microsoft came out with, but the main specs are published.


Question: Are there any "quick start" documents for sizing Hub, CAS, UM, Edge roles. For example based on general hardware how many users can a CAS support or how much SMTP data can a Edge/Hub support, etc. Is there a sizer app for this?

Answer: There is a great blog on the Exchange Team: http://msexchangeteam.com/archive/2007/01/16/432222.aspx, plus these TechNet links: http://technet.microsoft.com/en-us/library/aa998874.aspx and http://technet.microsoft.com/en-us/library/bb124518.aspx.  Also, HP just released some sizing tools - Check out http://h71019.www7.hp.com/ActiveAnswers/cache/70593-0-0-0-121.html.


Question: can LCR replicate the db to an UNC share on another server?

Answer: No, that is not supported.


Question: What do we use as a storage in the CCR?

Answer: There are no “special” requirements for storage if you are using CCR.  You need to ensure whatever storage you use is supported by Exchange Server 2007 in general.


Question: High Availability of Exchange 2007

Answer: http://technet.microsoft.com/en-us/library/bb124721.aspx.


Question: Can the .edb files be easily converted and/or exported to .xlsx files for use in Excel 2007, so that charting and conditional formatting can be added?

Answer: No, that is not possible.  These are the database files for the Exchange Mailbox store and cannot be converted to XLSX files.


Question: is legacy ntbackup.exe?

Answer: for the most part, yes.  NTBackup performs a streaming backup which is being de-emphasized.  As Mailbox databases continue to grow larger and larger, it will become harder and harder to provide a valid SLA if you have to resort to a streaming tape restore of 100 GB (as an example).


Question: what is inspector folder? the second being can we backup the lcr to a mapped netwoork share?

Answer: 1) CCR / LCR has built in integrity checks made on the log files prior to them being replayed into the copy db. This is facilitated by the Inspector directory.  2) Yes, you can perform a backup to a network share.  Remember, you cannot store the LCR copy of the database on a network share.


Question: Will Ntbackup quieese the exchange database while the backup occurs?

Answer: If you are referring to “snap shot backup”, NTBackup does not support this.  You will need to use a third party tool or Data Protection Manager 2.0 (when it ships).


Question: why would you verify Exchange aware backup? I thought that during the Exchange backup as ese is reading pages from the database they are being checksummed (ie verified)?

Answer: Performing a verify check during the backup process is “verifying” that the backup really did backup what it was supposed to.  The verify compares the backup data to the actual data to ensure it is valid.


Question: Can one have redundancy within Trasport Hub (not talking about clustering)...

Answer: Yes – if you install multiple Hub Transport server roles in each site, redundancy is built in.  For more information, see http://technet.microsoft.com/en-us/library/bb124721.aspx.


Question: Can I use NT backup to backup to a 32 bit machine?

Answer: If you are referring to running NTBackup on the 64 Bit Exchange 2007 server and streaming the backup file to a share on a 32 bit machine, that is indeed supported.


Question: Re redundacy...my question was more in line with having multiple say SMTP instance (for a lack of better word) in Transport hub..

Answer: As I previously answered, having multiple Hub Transports per site will provide this redundancy.


Question: You may have covered this, however which versions of Exchange suport which version of replication? Is it only the Exchange Enterprise version?

Answer: Local Continuous Replication (LCR) is supported in both the Standard Edition and Enterprise Editions of Exchange 2007.  Continuous Cluster Replication (CCR) is only supported in the Enterprise edition.


Question: sorry harold I keep missing these can i see this broadbcast and the previous one

Answer: Start here - http://www.microsoft.com/events/series/tnexchangeserver.mspx.  You will want to give it at least 3 days (just to be safe) before you see the “current” session posted for on-demand viewing.


Question: Each server role for Ex07 must be on a 64-bit OS??

Answer: Yes.


Question: What problems will you run into in using Exchange 2007's DR when your servers are in different physical locations (subnets).

Answer: Well at this moment you cannot span any of the CCR across multiple subnets.  If you wish to implement CC in different locations, you will need to “stretch” the subnet so that the two servers are on the same logical subnet.  With SP1, you will have a new replication called Standby Continuous Replication that will span subnets.


Question: what version of Windows 2003 supports 64 bit hardware?

Answer: 64 bit is available in both Standard and Enterprise editions of Windows Server 2003.


Question: i just wanted to know if say i lose a 64bit server and i have a 32bit win2k3 server running the 32bit edition. will it be possible to mount/recover database of the 64bit server on a 32bit one.

Answer: Specific to Exchange 2007, this is not supported.


Question: Will SCR work with non-clustered systems? I.e. can we use LCR and SCR together when SP1 comes out?

Answer: Source and target can be stand-alone, or in 2 different MSCS Clusters, on different subnets.  I don't know about combining LCR and SCR but you really won't have too.  http://msexchangeteam.com/archive/2007/02/23/435699.aspx.


Question: was local copy cluster previously known as single copy cluster? Thanks

Answer: No, there is no such feature known as “Local Copy Cluster”.  However, Local Continuous Replication (CLR) is new to Exchange 2007.  Single Copy Cluster in previous versions of Exchange is still called Single Copy Cluster in Exchange 2007.


Question: so does it also techincally apply to an exchange 2003 database which is forklifted for recovery on a e2k7 server [follow up from 64bit backup to 32bit server above]

Answer: I guess it depends on your definition of “Forklift”.  You cannot take a database from Exchange 2003 and mount it on Exchange 2007.  You can restore an Exchange 2003 backup to an Exchange 2007 server.


Question: Is it possible to get these web casts as a PDF slides that you can export through File - Print PDF? Thanks.

Answer: If you attend the live webcast, you can always print to PDF.


Question: I realize "stand-by replication server" won't be available till SP1, but is there any documentation (however brief) available on it now?

Answer: Here’s the blog post on the Exchange team blog: http://msexchangeteam.com/archive/2007/02/23/435699.aspx.


Question: when is DPM v2 going to be released?

Answer: It is due out by the end of this calendar year.  I am expecting it sooner though.  Harold


Question: is there an estimated throughput time for an offline defrag? like 10 GB/hour or something like that?

Answer: Not that I am aware of. There are quite a few variables that come into play.  There is some very basic information here: http://technet.microsoft.com/en-us/library/bb123761.aspx.


Question: Will microsoft in its own implementation of Data Protection Manager(DPM) make DPM R2 co-resident with the exchange server or will it run DPM on separate servers and run the backup over the LAN?

Answer: My best guess is that our internal implementation will have DPM on its own server.  For more information on DPM v2 and Exchange Server 2007 backups, please check out - http://download.microsoft.com/download/0/9/6/09623531-cb39-475a-88b7-1de963a99d9a/DPMv2_Datasheet-Protecting_Exchange_Server.pdf.


Question: is there a recommendation on how often an offline defrag should be run with eseutil?

Answer: Not really.  However, there is some information here: http://technet.microsoft.com/en-us/library/bb123761.aspx.


Question: so in Ex2k7, there are the new options LCR (W2K3 Std/EE SP1 x64), CCR (W2K3 SP1 EE x64), and then the traditional clustering is called SCC (single-copy cluster) (W2K3 SP1 EE x64)? thanks

Answer: Yes Looks great, and to peek into future - SP1 will introduce SCR - Standby Continuous Replication for enterprise


Question: Thanks! So I understand - does that mean that I could have two stand-alone servers replicating via SCR to a third stand-by server?

Answer: Too early to precisely answer this question.  I’m not sure if we will support a Standby Server being the target of multiple SCR partnerships.


Question: Is there any reason why Exchange Server 2007 cannot be run on Vmware ESX server? I recently read a WP from the VMWare www site that, although it is focused, on running Exchange Server 2003 as a VM on EXS, the wp also suggests that Excange Server 2007 can also be run in a VM environment.

Answer: From a technical standpoint, this can be done since VMWare ESX Server supports 64 bit Virtual Machines.  However, from a Microsoft support perspective, we will only be able to provide best effort support if you experience issues in this as we have not fully tested this scenario.


Question: Can you restore individual mailboxes from a CCR?

Answer: No, this is not what the CCR scenario addresses.


Question: Will SP1 perhaps add GUI tools to perform tasks such as Recovery Storage Groups, Public Folders, etc? The ones that are still "supported"?

Answer: There will be some enhancements to Public Folder management, but I don’t have specifics at this time.


Question: If the Active Copy of LCR get corrupted, the passive get it too?

Answer: Not necessarily. It all depends on what caused the corruption of the Active Database. If there was a controller error, then hopefully the Passive copy is controlled via a second controller that won't have the same error.


Question: do you know if the transaction logs still stop when they reach the highest number as in Exchange 2003?

Answer: Yes. However, we have incresed the number of possible logs to a much higher number - I can't remember the exact number. The log file now has 10 digits.


Question: will we not run eseutil /d regularly?

Answer: You can, but I wouldn't - Harold - :-)


Question: so we do not need to do an eseutil defrag quarterly any more? :) thanks

Answer: That was not necessarily a "recommendation". I do know quite a few companies that do that though. If you want to shrink your physical database device quarterly, then you would still do this.


Question: Can I have some kind of approve flow for messages? Like Lotus Notes... for example, every mail that comes with attachment PPT have to be approved by administrator.

Answer: I supposed you could get "creative" with a Transport Rule that keys in on attachment size. The action would be to redirect it to someone else. However this would include all attachments, not just PPTs. Outside of that, I really am not aware of this capability within Exchange.
