Businesses should always take care to secure their data at regular intervals. Short backup intervals are therefore reasonable. The time intervals between the backups should be limited to only a few days. Having access to a backup, the victims of the cryptolocker ransomware would have been able to access their backups and restore their data without major losses. However, it should be noted that during this process the backups should be saved to a physically independent drive and ideally with a versioning feature. For example, a USB hard disk would not have been sufficient.
