Hi All,
am using DPM 2010 to backup Exchange 2010 Mailbox DB. now i am seeing critical alerts in DPM console that replica is inconsistent. below is the error screenshot. only single DB is not getting replicate properly. i have done consistency check many times but no success.
srini
I have 2 mailbox servers with exchange 2010 that are members of dag1
MBX1 has db1,db2,db3 as active databases and db4,db5,db6 as passive databases
MBX2has db4,db5,db6 as active databases and db1,db2,db3 as passive databases
Question 1
Regarding the following statement that was mentioned in the DPM calculator
“Number of copies that will be protected in this site: Specify the number of copies of a mail database that you want to protect in a DAG. You can protect one or more mail databases with DPM. The number of databases that you protect will depend upon several parameters. Most often you will protect one copy of the database with DPM. DPM 2010 provides node based protection for Exchange 2010, so the state of the protected database - Active or Passive is not important in choosing which database you will protect, it is important to ensure that there”
Do they mean how many copy I need to take for each database in other words they mean I could backup each data base twice one from MBX1 and one from MBX2
Question 2
Regarding the topology mentioned above, is the inputs I typed meet my topology or not
Number of Mailbox Nodes in the DAG | |
Total Number of Mailboxes in this installation | 550 |
Total Number of Databases on each node | |
Number of copies of each database (1 Active + All Passive DBs) | |
Number of copies that will be protected in this site | |
Number of servers in Mailbox Server Role that will be protected | |
Number of Exchange DBs / LUN |
Question 3
If I want to take backup from MBX1 not MBX2 ,and MBx1 went down for any reason, I must change the protection group to initiate the backup from MBX2 , the dpm wouldn't take the backup from mbx2 as I didn't take backup from MBX02 for the first time
I think that taking backup from both server will need a lot of storage
Hello!
Im currently having a coexistance exchange 2010 and 2013 and would like to take backups of both using the same dpm server. Is this possible?
Hi All,
We have an Exchange 2010 Environment with DPM 2010 Backup solution. We have three Mailbox Servers in our Environment.
I have created One protection Group for all three Mailbox Servers database backup. I configured only passive database copies to take the backup.
Every day, we taking the Incremental Backup via 24 hours sync frequency.
When the backup starts at 12 AM, Only three database backups are running at a time. Rest of the jobs are in pending state. But we need to run multiple jobs at time through schdule.
Is ther any way, we can configure PG to run multiple jobs at a time for the Mailbox Server Backup ?

Hello,
I’ve started getting the following error message on my DPM 2010 server when it tries to create a Recovery Point on my Exchange 2010 server:
DPM failed to communicate with the protection agent on <Exchange 2010 Server> because the agent is not responding. (ID 43 Details: Internal error code: 0x8099090E)
When I go into the Management > Agents tab on the DPM management console and try to ‘Refresh Information’ for the Exchange 2010 server I get the following error:
Data Protection Manager Error ID: 316
The protection agent operation on <Exchange 2010 Server> failed because the service did not respond.
I’ve successfully run the following tests on both my DPM and Exchange servers:
Basic connectivity by using ping.
Next tested SMB (file sharing). net view \\<protected server name>
Next tested RPCand connectivity to Service Control Manager (SCM). This displays a list of services on the remote server when successful. Sc \\<protected server name> query
Lastly tested WMI/DCOM. When successful this command lists some basic information about the remote server. Wmic /node:"<protected server name>" OS list brief
I tried to manually restart the DPMRA service on the Exchange server but it timed out when trying to stop the service.
The Exchange Server Application Event Log is full of Event ID 7034 ‘The DPMRA service terminated unexpectedly. It has done this X time(s).’ errors.
I notice in the Application Event Log on the Exchange server that I got the following DCOM error just before I got the Event 7034 Error for the first time:
Event ID: 10010 Source: Microsoft-Windows-DistributedCOM Description: DCOM got error "2148007941" from the computer <Exchange Server> when attempting to activate the server: {DA6AA17A-D61C-4E9C-8CEA-DB25DEA52A95}
Can anyone provide any help or advice on what may have stopped the DPM Agent working on this one server and how to fix it? All my other protected servers are backing up as normal. Nothing has changed on the Exchange server.
If reinstalling the DPM agent on the Exchange server is the next best thing to try, what is the best process for doing this? Should I manually uninstall it from Add/Remove programs on the Exchange server and then try to install it from the DPM management console? Or, should I just try to ‘install’ it from the DPM management console without uninstalling it first?
What effect will this have on the Exchange Protection Groups and the pre-existing backups of the Exchange server?
Thanks in advance for any help,
Ros
How can I restore a Mailbox Database from an expired tape?
I have applied the work-around to catalogue the tape (mark as free > unmark as free) and I have been able to get the Database off tape, but how can I now mount this as a recovery database?
Our Sr. Admin is attempting to convert our Exchange 2010 pass-through disk to fixed VHD and found that our 2008 R2 Hyper-V clustered environment won't allow him to storage migrate a VM when it has any pass-through disk. He is formulating the next plan and since I'm responsible for DPM he is asking some questions. We see posts where people complained that after converting pass-through to VHD they couldn't backup with DPM because the disk signature was the same but DPM expects it to be a different/new disks. He is suggesting "having to create a new Exchange MB VM's using VHDs, add to the DAG, then add DB copies and remove the copies on the old VM with the pass-thrus and then remove the old VM. This option is actually not that bad and I suspect we'll end up going this route because its the most well udnerstood and trustable way to do it."
We wonder if we'll run into DPM not liking the Exchange DB being on a disk with a different signature? Will this cause, if it works, DPM to want to backup the entire DB. Its rather large.
Good day
We recently migrated from our Exchange server 2003 environment to a new 2007 exchange environment. After installing DPM 2010 on the exchange server i realized the i was not seeing the mail store, can anyone help with this issue?
Hi all;
I have an Exchange 2003 Server in our domain. Now I have replaced its functionality by another third-party software. So I have disconnected it temporary from the network and keep it active if someone needs its mailbox (so I can connect it to the network again).
I have DPM 2012 in my domain and so protected the Exchange Server with it. Now my question is that if I uninstall the Exchange Server from the server (to use the hardware for other services and applications), in the case of requiring some mails from the unisnatalled Exchange Server, can I install the Exchange Server again (in another hardware or maybe in virtualized environment) and recover the backed up data to it?
Thanks

I’ve been consolidating databases on our Exchange 2010 server by moving mailboxes from one store to another. So far I’ve moved around 200 GB of mailboxes and my problem is that DPM 2010 has been in the “Synchronizing” state on the "Protection" tab for the two stores involved for over 10 days now. I stopped moving mailboxes about a week ago in an attempt to let DPM “catch up” with all the moves, but it’s still synching. I can’t believe it’s taking this long to synchronize all the changes.
One weird thing is that if I go to the Monitoring tab and click on "Jobs" the Exchange server isn't in the list of servers currently synchronizing. The Exchange Server is in the list of jobs currently running under "Recovery Point". One of the databases has been running the "Recovery Point" for 60 hours and is up to 300 GB, thes other (the one I'm moving mailboxes from) is at 125 GB after 12 hours. So why does DPM say the databases are "Synchronizing" on the "Protection" tab, when they are actually creating a "Recovery Point"?
The bottom line is that my transaction logs are not getting flushed because DPM can’t back up until the synchronization (or recovery point?) is done.
Is it normal for this process to take this long? What if I run out of time before my transaction logs fill up? Can I just do a straight tape backup with DPM to get rid of the transaction logs? Or should I just start over on protecting these two databases?
Thanks!
I've got an Exchange 2007 SP3 CCR cluster that I was backing up with (originally) DPM 2007 and then 2010 with no issues. I built a new DPM2012 SP1 environment and am attempting to protect that same data. Client installation went fine, but when I try to protect the Exchange storage groups, I get the following error:
"One or more prerequisites for protecting this data source is missing.
Ensure that the following prerequisite software is installed on aewccrmbx01.AEWCCRCLUS01.AEW.COM and/or all nodes in the cluster:
Windows Server 2003 Service Pack 1 (SP1) with Knowledge Base article 940349 (http://go.microsoft.com/fwlink/?LinkId=99034)
- OR -
Windows Server 2008 (http://go.microsoft.com/fwlink/?LinkId=128812)
Update Rollup 4 for Exchange Server 2007 (http://go.microsoft.com/fwlink/?LinkId=99291) or later
ID: 31304"
Given how old that hotfix is, I'm fairly confident that I have it rolled up in a service pack - our Exchange environment is patched more or less up to date. Does anyone have any experience with this? Thanks!
Hi,
Im having trouble with one or two single databases where DPM admin console says there are replica issues. I have already tried complting a manual reseed but no luck.
Below is a quick screen shot. Any ideas?
Hi All,
i am seeing a strange issue with the Exchange 2003 restore. I am attempting to restore the entire mailbox store to a network location, however after a sucessfull restore i go to the folder and the edb is missing. i watch the restore and i can see the 99GB file up until the last few minutes and then it is gone.
Has anyone seen this before?
Thanks

I have a question regarding Exchange 2007 SP3 being backed up by MS System Center 2012 SP1.
Is such scenario supported because I've seen this technet post and got baffled.
In the first post it says that "All information in this section pertains to Microsoft Exchange 2003, Exchange 2007, Exchange 2010 and Exchange 2013 unless otherwise specified." and then exactly in the next step it says this "The minimum version of Exchange Server that System Center 2012– Data Protection Manager (DPM) can protect is Exchange Server 2010 with Rollup Update version 1 (RU1)."

Hi Guys,
I have one Exchange Node with 18 DB's protected under one Protection Group, we have 24 hours of disk backup synchronization with 5 days of retention and weekly tape backup setup. Now i have 2 questions.
1. All the backup jobs for these 18 DB's doesn't complete in 24 hours therefore recovery points for some DB are missed. How can i sort this?
2. I can see multiple jobs pending for the same DB for tape backup whereas it should only backup DB once. What could be the reason.
Some History:
We were protecting all the 18 DB's with 2 exchange nodes recently until we had problem with the second node. (Fyi, even though one exchange node was removed the disk/tape backups were still fine and we could see the recovery points to recover the required data).
We also had Sync frequency set to 4 hours which have now been changed to 24 hours, while it was on 4 hours sync the backup jobs were running fine and used to complete on time whereas now for past few days the sync doesnt complete although it has been set to 24 hours.
Consistency check is set to run if the replica becomes inconsistent, this is not changed at all.
The logs doesn't indicate anything unusual.
The storage is also more than 50% empty.
Your help will be much appreciated.
Thanks,
Sajeel
Hello,
I am using DPM 2012 server to protect exchange 2010 database on a tabe . now we need to restore a backuped exchange database on the different server according to our testing scenarios . we found only 1 recover option available and remaning recover options was dimmed as shown below :
1-Recover to original Exchange server location (Available).
2-Recover on different database on Exchange server (Dimmed).
3-Recover to a recovery database (Dimmed) .
4-Copy to a network folder (Dimmed).
5- Copy to a tape (Dimmed)
Hi,
From which Exchange Server am I commited to copy the ESEUTIL.exe and ESE.dll to the DPM Directory for protecting the whole Exchange databases from both products (2010 and 2013) ?
Thanks for replies.

I have setup DPM 2012 and am now backing up all my physical and virtual machines. I went to do a test restore of an Exchange mailbox today, only to find that it is NOT backing up the Exchange components. The Hyper-V node is backed up, but it is not recognizing it as an Exchange server. After researching this I copied the ese.dll and eseutil.exe files from the Exchange server to the DPM/bin folder and rebooted, but the protection group still doesn't see Exchange. I found information on-line that states DPM will only backup Exchange if it is in a DAG. Is this true?? Do I have to go buy another Exchange server license just to get DPM to backup Exchange??
