Performing Backups and Restores on a Linux Host

The Linux command line provides several utilities for creating and restoring backups. The `tar` command can be used to create compressed archives of files and directories. The `dd` command can be used to copy and restore drives and partitions, and to create image files of drives and partitions that can be used for backups. Both archives and image files, as well as regular files and directories, can be remotely synced using the `rsync` command. In this lab, you will be tasked with using these utilities to back up important data on a Linux host and sync it to a backup server.

  1. Challenge

    Use the tar Command to Create Backups of Directories on the server01 Host

    • Create an archive called full_bkp.tgz in /home/cloud_user using gzip compression on the following directories: /home, /etc, /opt, /usr/local, /root, and /srv.
    • Create an archive called var_bkp.tbz in /home/cloud_user of the /var directory using bzip2 compression.

  2. Challenge

    Use the dd Command to Create and Restore Backups of Devices on the server01 Host

    • Use /home/cloud_user/xvdg.img to restore the /dev/xvdg device (use a byte size of 4MB).
    • Create an image file of /dev/xvdf in /home/cloud_user/, and call it xvdf.img.bz (it should be compressed with bzip2).
    • Once the xvdf.img.bz file has been created, wipe the /dev/xvdf device using the /dev/zero device.

  3. Challenge

    Synchronize Backups to server02 Using the rysnc Command on the server01 Host

    • Sync (with compression) var_bkp.tbz and full_bkp.tgz to /home/cloud_user/archive on server02. Permissions and timestamps should be preserved.
    • Sync xvdf.img.bz to /home/cloud_user/archive. Do not use archive mode or compression.
    • Sync (with compression) the following directories to /home/cloud_usr/sync on server02: /home, /etc, /opt, /usr/local, /var/lib, /var/log, /root, /srv. Permissions and timestamps should be preserved.

  4. Challenge

    Validate the Backup Files and Directories Were Successfully Copied on the server02 Host

    • List the contents of the /home/cloud_user/archive directory.
    • List the contents of the /home/cloud_user/sync directory.
