  • Execute basic Linux commands

Exercise 2 - Best Practices

Data may get lost due to various reasons. Hence, it is necessary to follow certain practices which make the data recovery possible. A set of activities must be performed to ensure data availability is maintained all the time. This set includes:

  • Disk maintenance
  • Data backup
  • Update installation

Best practices are ways of performing these activities in the best possible manner from the data availability point of view.

Learning Outcomes

After completing this exercise, you will be able to:

  • Follow the best practices

Exercise 3 - Tools

Data could be lost. Human errors, malware attacks, and system failures are possible causes for loss of data and so data backed up regularly. When data is lost, the backup copy can be used to restore it back. This backup and recovery process can be categorized into three steps:

  • Creating a backup
  • Storing backup in a safe location
  • Using the backup data to retrieve the lost data

Various tools are available for performing backup and recovery. Tools make it easy to create a copy, provide the necessary functionality to store and deploy the required backup.

Learning Outcomes

After completing this exercise, you will be able to:

  • Use recovery tools
