Backing up NSX Manager data fails in JP locale (2150844)

  • 0 Ratings


  • NSX Manager backup fails.
  • You see the error:

    File upload action aborted due to insufficient storage or invalid file name.( 550 The filename, directory name, or volume label syntax is incorrect. )

  • NSX Manager Locale configuration is set to JP (ja-JP). To see current locale settings, log in to the NSX Manager virtual appliance and navigate to Manage Appliance Settings > Locale.
  • An error is logged in FTP server side logs with filename containing special character ? as short name of the day.


This issue occurs because some FTP servers do not accept backup filename with specific multi bytes characters.


This is a known issue affecting VMware NSX for vSphere 6.2.x and 6.3.x.

Currently, there is no resolution.

To work around this issue, set the locale to en-US.
