@MaxJamakovic , I might be missing a concern, though the Multi Node method does factor for nodes being down since you can add multiple data access nodes:
- You can configure the data access nodes as backup nodes for the network share subclient. The backup operation runs on the selected nodes. You can set data access nodes at the agent level or at the subclient level. The nodes set at the subclient level take precedence.
- On the Data Access Nodes tab, under Available Data Access Nodes, select the data access nodes that will participate in the backup operation, and then click Add.
The backup will run from the initial subclient server by default, though you can configure multiple nodes.
Let me know if there’s anything this method does not provide:
