If an NSX Manager or a Global Manager appliance becomes inoperable, or if you want to restore your environment to a previous state, you can restore from a backup. While the appliance is inoperable, the data plane is not affected, but you cannot make configuration changes.
You can restore an NSX-T Data Center configuration back to the state that is captured in any of the backups.
- You must restore to new appliances running the same version of NSX-T Data Center as the appliances that were backed up.
- If you are using an NSX Manager or Global Manager IP address to restore, you must use the same IP address as in the backup.
- If you are using an NSX Manager or Global Manager FQDN to restore, you must use the same FQDN as in the backup. Note that only lowercase FQDN is supported for backup and restore.
