To configure the NSX backups for the environment, you need to follow these steps:

• Verify that an SFTP server is available on the network and obtain SFTP fingerprint. You can use thesearch_web("SFTP server availability")tool to find some information on how to set up and check an SFTP server. You can also use thessh-keyscancommand to get the fingerprint of the SFTP server. For example,ssh-keyscan -t ecdsa sftp_serverwill return the ECDSA key of the sftp_server. You can compare this key with the one displayed on the NSX Manager UI when you configure the backup settings.
• Configure NSX Backups via NSX Appliance Backup. Log in to the NSX Manager UI with admin credentials. The default URL is https://. Select System > Lifecycle Management > Backup & Restore. Click Edit under the SFTP Server label to configure your SFTP server. Enter the FQDN or IP address of the backup file server, such as 10.10.10.100. The protocol text box is already filled in. SFTP is the only supported protocol. Change the default port if necessary. The default TCP port is 22. In the Directory Path text box, enter the absolute directory path where the backups will be stored, such as /data. The directory must already exist and cannot be the root directory (/). Avoid using path drive letters or spaces in directory names; they are not supported. In the Passphrase text box, enter a passphrase that will be used to encrypt and decrypt the backup files, such as VMware1!. Click Save to create the backup configuration.
• Configure Scheduling Criteria. On the Backup & Restore page, click Edit under the Schedule label to configure your backup schedule. Select Enabled from the drop-down menu to enable scheduled backups. Select Daily from the Frequency drop-down menu to run backups once every 24 hours. Select a time from the Time drop-down menu to specify when the backup will start, such as 12:00 AM. Select Enabled from the Additional Backup Trigger drop-down menu to run backups when there are changes published to the NSX environment. Click Save to create the backup schedule.
• Verify that a backup file has been created on the SFTP server. On the Backup & Restore page, click Start Backup to run a manual backup and verify that it completes successfully. You should see a message saying “Backup completed successfully”. You can also check the status and details of your backups on this page, such as backup size, duration, and timestamp.Alternatively, you can log in to your SFTP server and check if there is a backup file in your specified directory path, such as /data.
