Chapter 7. Performing System Backups and Restorations

Objectives

The following test objectives for Exam CX-310-200 are covered in this chapter:

Given a backup requirement, develop a backup strategy that includes scheduled backups, number of tapes required, naming conventions, command protocols, and backup frequency/levels.

• Solaris 10 provides several utilities for copying data between disks, tapes, and other types of media. You need to understand the capabilities of each utility and determine which is best for a particular circumstance. This chapter describes all the utilities and commands used to back up and restore data on a Solaris system. When you're finished with this chapter, you should be able to develop a scheduled backup strategy and determine the number of tapes required, command protocols, and backup frequency/levels for any given scenario.

Back up a mounted file system by creating a UFS snapshot and performing a backup of the snapshot file.

• You need to understand how to create a read-only image of a mounted file system using the fssnap command. You also need to know how to backup the UFS snapshot to tape.

Restore data from a UFS snapshot and delete the UFS snapshot.

• You need to understand the methods of restoring an entire file system from a snapshot and removing a snapshot when it is no longer needed.

Explain how to perform UFS restores and special case recoveries.

• You need to understand all the steps required to restore a file or file system from tape for each of the various Solaris backup utilities.
