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.

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

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

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