Veeam Explorer for Microsoft Exchange allows recovery of items that are under litigation hold or in-place hold. This feature is essential for compliance and legal discovery processes where emails and other items need to be preserved and may be subject to eDiscovery requests. It is not used for restoring databases from backups created with Veeam RMAN plug-in, exporting to BAK files, or restoring original passwords for account objects.References:

Veeam Plug-ins for Enterprise Applications provide a transactionally consistent backup of databases and their database logs. This ensures that the backup is not only complete but also consistent at a transactional level, capturing all transactions up to the point of the backup. This is crucial for databases to ensure data integrity and consistency when restored.

For deploying the Veeam Agent on Amazon EC2 instances running Windows and Linux operating systems without direct network access from the Veeam Distribution Server, the appropriate type of Protection Group to use is D: Cloud machines. The "Cloud machines" protection group type in Veeam Backup & Replication is specifically designed for protecting cloud-based workloads, including instances in public cloud environments like Amazon EC2. This protection group type allows the Veeam Agent to be deployed and managed remotely, even when the Veeam Distribution Server cannot directly access the instances over the network. It facilitates centralized management of backup tasks for cloud instances, ensuring that the EC2 instances are adequately protected as per management's request, despite the network accessibility constraints.
