Problems arising from user account configuration and file permissions assignments are sometimes seen only over time. Backing up and restoring Linux hosts can solve these and many other problems. In this course, I will describe common user and file permissions problems in Linux and potential solutions, followed by troubleshooting user account and file permissions issues. I will then manage user-elevated permissions with sudo and the SUID file system bit. Next, I will configure file system quota limits for users and groups and revert cloud and on-premises Linux servers to previous states. Lastly, I will backup and restore a cloud-based Linux virtual machine. This course can be used to prepare for the Linux+ XK0-005 certification exam.
