Redundancy ensures more security. Therefore, server hard drives work in a RAID array, so that all data is automatically stored two or more times. The most common method is RAID1, where the data is mirrored on two disks. Depending on the offer, it is a hardware or software RAID.
In the case of hardware RAID, hardware controls the hard disk connection: the controller. Software RAID does not use its own control software; instead, the server processor has command of the hard disks. This can, but does not have to, lead to performance losses for the server. And in terms of security, a hardware RAID can even cause more problems than software RAID, namely when the controller fails.
Updates for system and software
Important for product safety are regular updates of the operating system and the software. Critical security updates should be made immediately to prevent cyber attacks of all kinds. With shared hosting, the customer must rely on the hosting provider to maintain the systems.
On the other hand, anyone who rents a dedicated root server is responsible for updates to the operating system and the software itself. The administration requires expertise and costs time, which is why many users prefer to use a managed server, where the hosting provider takes care of the system maintenance. But beware: Which services belong to the server management and which not, regulates each hoster differently. Therefore, you should be informed before deciding on a specific offer.
Server monitoring around the clock
Despite regularly maintained systems and redundant hardware, any hosting solution can fail. Network, hardware or software problems can be the reason. Solving the problems as quickly as possible is the essential task; to recognize the causes, the more difficult ones.
Monitoring systems help. They monitor server systems, ideally around the clock, and report abnormalities to the customer. Depending on the provider, the customer will be notified by e-mail and / or SMS. Rarely is the notification via messenger, Twitter or even possible by phone. In any case, the customer can respond to the problems himself or consult the host. Customers of a managed server have advantages over root server users.
