It is highly impossible for all the storage devices to transfer their media to another device. If the hardware fails, the question here is how easy it will be to confiscate the physical media and pile it onto a replacement device? The worse situation is if the hardware supplier steps out of this business, how to transfer your backup to third party hardware?

How long does an industry or company regulation require data to be stored?

Permanence is a serious topic of concern. Systems that rely on magnetic media such as tape or hard discs are more prone to distortion due to electromagnetic interference as well as mechanical failure.

This means that they are forced to transfer the stored data to new systems during regular intervals. This involves two or three times of migration in a decade to maintain the integrity of data. On the other hand this will significantly add to the total cost. Optical media recommends a greater lifespan, with DVD and Blu-Ray certified to last for 50 years and with the advancement of new technology available there are hardly any chances of distortion.

Where will the hardware exist?

Server rooms are often found in basements that may be susceptible to flooding, or other storage areas where they are more prone to being knocked around. What may happen if the data storage unit is physically damaged - will the data survive? Server rooms commonly generate a lot of heat and if they are cooled individually, the risk of system failure is notably increased, so air conditioning systems is mandatory which involves expensive installation and running.
