Restoring a backup restores the state of the network at the time of the backup. In addition, the configurations maintained by NSX Manager or Global Manager appliances are also restored. For NSX Manager, any changes, such as adding or deleting nodes, that were made to the fabric since the backup was taken, are reconciled.
DNS entries (name servers and search domains) are not retained when you restore from a backup.
You must restore the backup to a new NSX Manager or Global Manager appliance.
If you had a cluster of the NSX Manager appliance when the backup was taken, the restore process restores one node first and then prompts you to add the other nodes. You can add the other nodes during the restore process or after the first node is restored.
If you had a cluster of Global Manager appliances, you can only restore one node using the restore process. You must create the cluster after the restore of the first node completes.
Prerequisites
- Verify that you have the login credentials for the backup file server.
- Verify that you have the SSH fingerprint of the backup file server. Only SHA256 hashed ECDSA (256 bit) host key is accepted as a fingerprint.
- Verify that you have the passphrase of the backup file.
- Identify which backup you want to restore by following the procedure in Listing Available Backups. Take note of the IP or FQDN of the NSX-T Data Center appliance that took the backup.
- If you had an NSX Intelligence appliance installed on the NSX Manager when the backup was taken, you must upload the OVA file of that same version of the NSX Intelligence appliance on the new NSX Manager before you restore the backup. See Installing and Upgrading VMware NSX Intelligence for the installation information.
