Fail-safety is a feature of computer systems and networks that characterizes failure-free and trouble-free continuous operation. In order to increase reliability, there are various techniques and procedures with which systems and transmission paths can be designed redundantly, supply voltages can be secured and data can be duplicated.

One factor for increasing reliability in computer systems is heat dissipation. Optimal heat dissipation and the reduction of the ambient temperature of the electronic components considerably increase reliability. Furthermore, server farms can be used in systems engineering, where if one server fails, another takes over its tasks. Network technology, on the other hand, uses fail-safe, redundant network structures and therefore plays a rather subordinate role in increasing fail-safety.

The situation is different for the supply voltage. UPS systems are used to ensure that the power supply is always available, and they come into operation when the supply voltage is affected by strong voltage fluctuations or fails completely.

As far as data duplication is concerned, there are various methods for creating backup copies, replicating data and storing it on different servers, mirroringhard disks or striping data blocks, which are implemented with RAID systems.
