EnableScaleOutExtentMaintenanceMode

WHAT IT DOES

What EnableScaleOutExtentMaintenanceMode does on Veeam VBR v13 MCP Server

AI agents invoke EnableScaleOutExtentMaintenanceMode to trigger actions in Veeam VBR v13 MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why EnableScaleOutExtentMaintenanceMode needs a policy

Enabling maintenance mode on a Scale-Out Backup Repository (SOBR) extent triggers an external operational state change on backup infrastructure. This is not a simple data read or write — it actively changes the operational mode of a storage extent, potentially causing Veeam to evacuate data, stop using that extent, and affect ongoing backup/restore jobs.

EnableScaleOutExtentMaintenanceMode Rate-limited

EnableScaleOutExtentMaintenanceMode stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
