Where do I go to back up my files in Linux?
The cd command puts us in the / directory (or root). This is the home to all files on your Linux installation. After that just run the backup command and sit back. Once the command above has finished its run, look for the backup.tar.gz file inside the / folder and save it to an external file system.
How often should I backup my Linux system?
Do a full system backup once a week, and an incremental backup daily. If you need more frequent backups, you should be running twin or triplet systems, and be able to switch from one to the other on demand. Other than backup frequency and backup device, there are (or should be) no difference in the backup requirements of any users.
