The most likely reason someone owns SDLT tape media is to backup their valuable data so that in case of an accident which damages the main database the business flow may still continue by using an older database. However due to environmental conditions, bumps and shocks (during shipping or moving the tape cartridges) and dust/grime your tape cartridges can still be damaged thereby causing you to lose your extremely valuable data. These SDLT cases although simple are an effective method of preventing such disasters from occurring as they can safeguard your SDLT tape media well against dust/grime and environmental conditions. They also provide a limited form of protection against shocks and bumps, especially during shipping.
