Unless they want to risk data loss, cloud admins need to invest some time in a solid backup plan. Cloud-based backups, in general, ensure that data is copied and stored to a secondary location, such as an archival service. If the source data is compromised, enterprises can retrieve the backup data and restore to a state before the compromising event.

If there is a provider outage or security breach, the whole system could fail.
