When you copy a database from an Exchange Server and place it on a different Exchange Server, then you may call the process ‘Seeding.’ Thus, it becomes a replica of your database where the entire data is present. Seeding is performed using the ‘Update-MailboxDatabaseCopy’ cmdlet.
Here are some points which you should understand before running the cmdlet –
Here is the syntax of the cmdlet –
The cmdlet will seed the copy of the DB322312 on Server NDR32 using NDR53 as the Source Server.
If the cmdlet did not run correctly, then it will not create a copy at the destination server, and there will be an error at the event log.
MSExchangeRepl Event ID: 4113
Database redundancy health check failed. Database copy: DB322312 Redundancy count:1
Error: Passive copy ‘DB322312\NDR32’ is not in a good state. Status: FailedAndSuspended
You can also check the copy status using the Exchange Management Shell with a cmdlet.
To fix the error, you need to update the mailbox database copy running the cmdlet:
For a longer reseeds, if you want to keep the PowerShell closed, then use the below cmdlet:
The DeleteExistingFiles cmdlet deletes the existing log files to avoid any error messages:
Before running the reseeding cmdlet, the Exchange Administrator should check multiple points which are necessary for copying the database.
You can also use the Exchange Admin Center to reseed the copy process.
So, this is the whole process of handling a ‘mailbox database copy failed and suspended’ situation. Thus, you can handle the situation using various PowerShell cmdlets and Exchange Admin Center.
But, if the database faces any corruption, sometimes the copy process will not be fruitful. In that case, try a professional Exchange recovery tool. Which makes Exchange server working more easy and secure.
Kernel for Exchange Server recovery tool is a powerful Exchange database corruption remover which can access the entire database and remove the corruption in the least time. After recovering the database, you can directly save the data to the destination Exchange Server.
