Hello Friends, Today I will show you how you can
create a Recovery database in Exchange 2016. Recovery database can be very
useful if you want to restore few emails of a user mailbox or want to restore
the whole mailbox. Recovery database is a feature in Exchange 2016 which helps
us to restore a mailbox from a back up copy of mailbox database. Recovery
database allows us to merge the emails of a mailbox from a back up copy of a
mailbox database with a mailbox which is currently residing on a mounted copy of
mailbox database.
I have an user MSFT , The user had an important email on his mailbox however the
user accidentally deleted all the email on his mailbox now the user wants those
emails back.
I have restored a copy of the mailbox database
from my back up utility, The name of the mailbox database is mailbox database
is "Mailbox Database 1978255080.edb".
I will use the restored mailbox database to restore the deleted emails for the
MSFT mailbox.
Run the below command from Exchange Powershell to
create a Recovery database.
New-MailboxDatabase -Recovery -Name
<RDBName> -Server <ServerName> -EdbFilePath
<RDBPathandFileName>
Once the Recovery database is created then
restart the Microsoft Exchange Information store service. Run the below command
from Exchange Powershell.
Restart-Service MSExchangeIS
We will have to mount the recovery database now
however before mounting the Recovery database we will have to bring the
Recovery database in to clean shutdown
so that the Recovery database can be mounted.
Run the below command to repair the Recovery
database.
eseutil /p "C:\Recovery\Mailbox Database
1978255080.edb"
Note:- My database couldn't be repaired using soft
recovery so I have used hard repair switch to repair the mailbox database. You
can also use the soft recovery switch to repair the mailbox database.
Recovery database is in clean shutdown, We can
check by running the below command.
eseutil /mh "C:\Recovery\Mailbox Database
1978255080.edb"
Run the below command to mount the Recovery
database.
Mount-database <Recovery database>
Run the Below command to find out the mailboxes
that resides in the Recovery database.
Get-MailboxStatistics -Database <Recovery
database>
The mailbox that needs to be restored should show
up. We can see that MSFT mailbox is in the Recovery database.
Run the below command to restore the mailbox with
name "MSFT" from Recovery database to the user mailbox that has the
email address msft@shubh.com.
New-MaiboxRestoreRequest -SourceDatabase Rec_db
-SourceStoreMailbox "MSFT" -TargetMailbox msft@shubh.com
Once the command is run, The Restore process will
be initiated. We can see here the restore process is in Queued state. We can
check the status of the restore process by running the below command.
Get-MailboxRestoreRequest
Now the MSFT mailbox is restored. The accidentally
deleted important email is back in the mailbox.
Run the below command to Remove the restore
request, This can be achieved using Remove-MailboxRestoreRequest command.
Get-MailboxRestoreRequest -Status Completed |
Remove-MailboxRestoreRequest
Note:- A mailbox restore can be done using
different attributes, Below is another example to restore a mailbox using
different attributes.
You can find out the mailbox GUID using the below
command.
Get-MailboxStatistics -Database rec_db |fl
DisplayName,*GUID*
and then use the below command to restore the
mailbox that has the MailboxGUID 44b7f929-786f-4fd1-a001-db903279b9f3 on
mailbox database Rec_db to the target mailbox with the alias MSFT.
New-MailboxRestoreRequest -SourceDatabase Rec_db
-SourceStoreMailbox 44b7f929-786f-4fd1-a001-db903279b9f3 -TargetMailbox msft
