To be able to restore Microsoft SQL Server VMs backup data, Veeam Mount Service – a component that is responsible for mount operations – creates an additional mount point on the original virtual machine, and, if necessary, on the staging Microsoft SQL Server.
Mount to the staging server is used when recovering to the specific transaction, or if Veeam Backup & Replication does not have information about databases. For example, if you initiate database recovery from the storage snapshots.
To create a mount point on Microsoft Windows machines, Veeam uses iSCSI protocol. The original virtual machine or the staging server acts as an iSCSI initiator. The mount server that is associated with the backup repository acts as an iSCSI target. The iSCSI mount point is non-persistent and exists during the recovery process only.
