If you want to know the Quorum type then need to run the below command

Command Input : Get-ClusterQuorum -Cluster “DAGName” | fl

Output :

Cluster DAG1
QuorumResource File Share Witness (\ mb3.netsaints.comDAG1.netsaints.com)
QuorumType Based on Nodes

 

This below command will give the Information about LastFullBackup

 Get-MailboxDatabase -Status | ft name, last*

 

MDBBKP

 

Here you can use the Switches “-Auto or -Wrap” to get the information with breaks……

 

This Command will give the information about all the list of the backup status of all Mailbox Databases Specific Server in your Organization

E.g.: Get-MailboxDatabase -Server EXCH2K10 -Status | Format-Table Name, *Backup*

 

This Command will give the information about all the the list of the backup status of all Mailbox Databases in your organization

Get-MailboxDatabase -Status | Format-Table Name, Server, *Backup* -wrap

 

To get the output in CSV file the below Type the below Command

Get-MailboxDatabase -Status | Format-Table Name, Server, *Backup* -wrap >C:\Backup.txt

 

If you have another Site (DR) and if you want to enable DAC mode below is the command

DAC MODE :

Set-DatabaseAvailabilityGroup -Identity DAG2 -DatacenterActivationMode DagOnly
