1. You are considering the purchase of a tape backup system to protect data stored on servers in your organisation. Given the information below, calculate the total cost of ownership of the tape backup system over 5 years.

The SafeStore 500 backup drive is available for purchase at $4,850. Media (tapes) cost $100 each and you estimate that you need 15 to meet your weekly backup requirements. Although the stored data is guaranteed safe for up to 50 years, the manufacturer recommends that tapes not be kept in constant use (weekly) for more than 6 months before being retired or used for long time archiving.

You decide to invest in the AutoStore-Pro software that takes care of scheduling backups. The software is licensed on an annual basis for $250 PA. You also attend a half day training session, "Disaster Recovery using AutoStore products", at a cost of $150.
