Dell EMC Metro node 7.0.1 Product Guide

Backup metadata volumes

Backup metadata volumes are point-in-time snapshots of the current metadata, and provide extra protection before major configuration changes, refreshes, or migrations.

Backup creates a point-in-time copy of the current in-memory metadata without activating it. You must create a backup metadata volume in any of these conditions:

  • As part of an overall system health check before a major migration or update.
  • If metro node permanently loses access to active meta-volumes.
  • After any major migration or update.
