You get a banner and an alert.\n- ### Backup protection at a glance\n\nEach guest shows its newest backup and whether it is protected, stale or has none.\n- ### Checked before it runs\n\nTarget node, VMID, storage and network are checked per guest before the restore starts.\n- ### IPs and port forwards\n\nKeep the IP or take a new one on the target, and port forwards move along.\n- ### No double guests\n\nWhen the failed node returns, its old copies are stopped and you are asked to clean them up.\n- ### Never automatic\n\nFailover starts only when you click it, so a short network blip never restores anything."},{"heading":"How to use it","content":"Up and running in 4 steps, all in the panel.\n\n1.
