Case Project 4-1: Dealing With A Disk Crash

Case Project 4-1: Dealing with a Disk Crash These case projects use the information found in the lesson chapters. You should take care to

Last week, a disk containing CSM Tech Publishing's current project manuscripts crashed. Fortunately, there was a backup, but all files that had been added or changed that day were lost. A new disk had to be purchased for overnight delivery, and the data had to be restored. Several days of work time were lost. The owner of CSM Tech wants to know what can be done to prevent the loss of data and time if a disk crashes in the future. The server currently has two disks installed: one for the Windows boot and system volumes and one for manuscript files.

The disk used for manuscript files is about one-third full. There's enough money in the budget to purchase up to two new drives if needed. What solution do you recommend, and why?

To mitigate the risks associated with disk crashes and to prevent significant data loss and operational downtime in the future, implementing a comprehensive data protection and disk management strategy is essential. Given the current setup, where the server has two disks—one for the operating system and one for manuscript files—and considering the capacity of the manuscript drive being only one-third full, a suitable solution involves adding redundancy and improving data recovery processes.

The most effective approach is to implement RAID (Redundant Array of Independent Disks) technology, specifically RAID 1 (mirroring) or RAID 5, depending on the available hardware support and budget constraints. RAID 1 involves mirroring data across two disks, ensuring that if one disk fails, the other contains an exact copy, allowing continuous operation with minimal data loss. Since the office has the budget for two additional drives, a RAID 1 setup can be easily implemented by installing two new drives and configuring them as mirrored disks for the manuscript storage. This setup provides real-time redundancy, minimizing the risk of data loss due to disk failure.

Implementing RAID 1 will also streamline recovery processes, as data can be quickly restored from the mirrored disk without the need for lengthy restoration procedures from backups. Additionally, it enhances uptime, crucial for productivity in a publishing environment where delays can be costly. To further safeguard data, regular backup schedules should be maintained, including off-site backups to protect against physical disasters such as fire or theft.

Another recommended solution is to consider upgrading to automated backup and snapshot systems, such as implementing software that periodically creates system restore points or snapshots of critical data. This approach complements RAID by providing version history and quick recovery options if a malicious attack or accidental deletion occurs. Furthermore, conducting routine disk health monitoring allows early detection of potential disk failures, enabling preemptive replacement before catastrophic failure occurs.

In conclusion, incorporating RAID 1 for the manuscript drives is the most cost-effective and reliable solution given the existing budget and hardware setup. Coupling RAID with a robust backup and monitoring strategy will significantly reduce data loss risk, improve recovery times, and ensure continuous access to critical project files, thereby safeguarding the operational continuity of CSM Tech Publishing.
