NSX backup history is empty while NSX backup is successful

Products

• VMware NSX

Issue/Introduction

NSX is configured to use auto backup.

You may have seen a notification in NSX UI indicating that the NSX backup is not detected.

Under "Systems", "Backup & Restore" setting, the backup history is empty while the last backup jobs were completed successfully.

Environment

VMware NSX

Cause

The SFTP user configured for NSX backup does not have all the permission needed. Likely "read" permission is missing such as "-wx" or "3" for the user or group permission. 

In a cloud environment, the user permission may be limited to read, write, but without list for the storage container. 

Essentially, the backup folder becomes a blind dropbox. 

Resolution

Workaround: Add the required permission to the NSX backup user from the SFTP server.

Example: chmod u+r backup_folder_name
