• 206.2 Backup Operations

Almost every seasoned system administrator, as well as many end users, has horror stories that revolve around lost data. Millions of dollars have been lost and heads have rolled because either no backup strategy was put in place or the backup strategy wasn’t followed.

Data is a serious business, and you don’t want to be the one, hat in hand, explaining why critical company data has been lost forever. You must create a solid backup strategy and make sure it is implemented correctly.

This chapter introduces some of the basics that you should know when creating your backup strategy. You learn to answer the questions of what should be backed up and what tools should be used. You also learn about some of the standard backup tools that come with Linux as well as some of the third-party tools that are available.
