Storage policies in Commvault play a crucial role in storage management by dictating how data is stored, retained, and accessed. These policies define storage-related rules and workflows, ensuring efficient data management and compliance with organizational requirements.

Backup job history benefits organizations by identifying areas of improvement in backup processes. By analyzing historical data, organizations can pinpoint inefficiencies, optimize workflows, reduce risks, and enhance overall data protection and security, leading to improved backup performance and operational efficiency.

In Commvault, the different types of backup scheduling available are Full, Differential, Incremental, and Synthetic Full. Full backup captures all data in the selected data set, Differential captures changes since the last Full, Incremental captures changes since the last backup, and Synthetic Full creates a new Full from previous Incremental or Differential backups.

Commvault offers integration with various cloud platforms, allowing organizations to manage their data seamlessly across different cloud environments. This integration ensures data accessibility, security, and efficient data management practices in hybrid and multi-cloud environments.

The assumptions of a multiple linear regression model can be validated by checking the residuals plot for randomness (i.e., no patterns), conducting a normality test on the residuals to check if they are normally distributed, and checking for homoscedasticity (i.e., constant variance of the residuals).

Interval estimation in inferential statistics is a method by which a range of values is provided that is likely to contain the population parameter. Instead of a single value, it provides an interval of estimates making it more flexible and informative than point estimation.

Non-parametric tests treat data points by analyzing their ranks rather than their actual values. This makes non-parametric tests less sensitive to extreme values and makes them a good choice when dealing with skewed data or data with many outliers.

The Central Limit Theorem is a fundamental theorem in statistics that states that the sampling distribution of the sample means approaches a normal distribution as the sample size gets larger, no matter what the shape of the population distribution. This outcome is significant because it enables us to make statistical inferences about the population mean based on the distribution of sample means.

Checking the assumptions of a multiple linear regression model (like linearity, independence, normality, and homoscedasticity) is crucial to ensure the validity of the model and its estimates. Violations of these assumptions can lead to biased or inefficient estimates, and inferences made from such models could be misleading.

Stepwise regression assumes a linear relationship between the predictors and the response. It might be problematic when the true model is non-linear, leading to incorrect inferences.
