backup.sh how to use?

When i am changing location of scratch in esxi configuration, after reboot, it returns to default value. On the forum, i read that i must use backup.sh to save current configuration via putty.

I am trying to use backup.sh but cannot understand or find in google, how to do it

[root@localhost:~] /bin/backup.sh

Usage: /bin/backup.sh IsShutdown [PATH_NAME]

[root@localhost:~] /bin/backup.sh /etc/vmware/locker.conf

Invalid parameter for is_shutdown: /etc/vmware/locker.conf

[root@localhost:~] /bin/backup.sh true

Invalid parameter for is_shutdown: true

Is there any special syntaxis?
