Backup Capacity Calculator

Formula

The formula to calculate the Backup Capacity (BC) is:

\[ BC = \frac{D \times R}{1 - C} \]

Where:

Backup Capacity (BC): The additional storage space reserved for use in the event of a system failure or data loss.
Total Data Size (D): The total amount of data to be backed up.
Redundancy Factor (R): The number of copies of data to be stored.
Compression Ratio (C): The reduction in data size achieved through compression.
Significance: Backup capacity is crucial for data management and disaster recovery strategies, ensuring that important data can be recovered and restored in case of disruptions.

Let's say the total data size (D) is 500 GB, the redundancy factor (R) is 1.5, and the compression ratio (C) is 0.2. Using the formula:

\[ BC = \frac{500 \times 1.5}{1 - 0.2} = 937.5 \]

So, the Backup Capacity (BC) is 937.5 GB.
