This page shows how to restore an admin workstation from a backup.
Restore the admin workstation from backup
When you upgrade an admin workstation, then by default the gkeadm upgrade command also saves a backup file. Later, if you no longer have an admin workstation, or if you have lost some of the files that were on your upgraded admin workstation, you can use this backup file to create an admin workstation that is restored to what was in place immediately after the upgrade.
To create an admin workstation from a backup file, run this command:
gkeadm create admin-workstation --restore-from-backup ADMIN_WORKSTATION_NAME-backup.tar.gz
Replace ADMIN_WORKSTATION_NAME with the name of the admin workstation.
