Example: Restoring Teradata QueryGrid

To restore the system, run:

/opt/teradata/tdqgm/bin/restore.sh <backup_file>
Enter public address for this manager instance [<public_address>]:

where <backup_file> is the path name of the backup ZIP file, similar to ~/tdqgm-backup-2016-06-16.zip and <public_address> is the hostname or IP address of the Teradata QueryGrid Manager system; for example: test.mydomain.com or 198.51.100.20.

Result (note, enter y at the prompt):

A restore from backup removes all data previously saved on this manager instance and 
all local manager services are restarted.  This manager instance becomes a standalone cluster. 
Other managers can join this instance using the join-cluster command.  

Do you wish to continue? [y/n]:   y
