Execute backup policies on demand
For a quick way of verifying or testing the correct resources are applied to your backup policy is to select one or more policies by selecting the corresponding checkbox and clicking the Execute Now button to fire a backup policy straight away.
The subsequent backups that are generated can be reviewed in the Backups page from your account dashboard. You can also see the details of the policy execution as it happens on the Jobs page.
The Execute Now option is also useful if you want to run a backup policy outside of your regular schedule.
