C.2 Sample restore script

As an alternative to using Settings→Actions→Restore from backup from the appliance UI, you can write and run a script to automatically restore the appliance from a backup file.

NOTE: Only a user with Infrastructure administrator privileges can restore an appliance.

Example 9 “Sample restore.ps1 script” provides a sample script that restores the appliance from a backup file or obtains progress about an ongoing restore process.

Sample script

If you do not pass parameters to the script, the script uploads and restores a backup file.

1.Calls query-user()to get the appliance host name, user name and password, and backup file path.

2.Calls login-appliance()to issue a REST request to get a session ID used to authorize restore REST calls.

3.Calls uploadTo-appliance()to upload the backup to the appliance.
