After completing a planned failover for VMs to the disaster recovery site, the typical actions available in Veeam Backup & Replication for a failover plan are:
Undo: This allows you to reverse the failover and return the VMs to the original location.
Start: This would be used to initiate the failover plan if it needs to be executed again.
Edit: This option permits modifications to the failover plan.
Delete: This allows the removal of the failover plan if it is no longer needed.
There are no options for Copy in the context of a failover plan, and the Cancel option is typically available before and during the failover process, not after completion.

Explanation
When performing a file-level restore, you need to specify a host on which the restored file system will be mounted. This host can be a separate machine or the same machine where Veeam Backup & Replication is installed. The restored files from the backup image will be mounted on this host, allowing you to browse and extract the specific files or directories you need.

To properly back up Microsoft Exchange databases in an environment using Veeam Agent for Microsoft Windows, you would need to configure "Exchange Processing." This option allows Veeam to interact with the Exchange server, ensuring that it quiesces the databases and transaction logs correctly to create consistent backups of the Exchange data. This is essential for the proper backup and recovery of Exchange databases, especially in environments with Database Availability Groups (DAGs) where data consistency is critical.
