When you upgrade NSX Manager to NSX 6.4.1 or later, a backup is taken and saved locally as part of the upgrade process. You must contact VMware customer support to restore this backup. This automatic backup is intended as a failsafe in case the regular backup fails.

After NSX Manager is successfully upgraded, new commands are available in privileged (enable) mode to allow you to manage the backup files. You can use these commands to list, copy, or delete the backup files.

If you don't delete them, the backup files remain in place until the next upgrade. When the next upgrade is started, the backup files are deleted, and a new backup is taken.
