It really is that simple. Time Machine makes it easy for you to back up your Mac.
According to Apple , Time Machine will automatically make hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for all previous months. As your storage device becomes full, the oldest backups are deleted so newer backups can continue to use the device. The first time you create a backup using Time Machine it will probably take a long time as it is backing up all of the selected files from your Mac.

After the initial backup, only new or changed data is backed up, unless you force a full backup. This method of backing up, known as incremental backup, saves time and storage space by not making unnecessary duplicate copies of files. It does, however, save multiple copies of files that change, so you can go back to get previous versions as long as there is room on your backup storage device. For this reason, it is recommended that you obtain the largest storage device that you can so you can retain your old backup versions for a long period of time.
The second method of backing up your Mac also requires the use of an external storage device to hold a clone of your hard drive. The external drive needs to be at least as large as your primary disk in order to be sure that there will be enough room to store the cloned copy. A clone of your disk indicates that the disk is copied bit-by-bit to create an exact copy of your primary drive.

Clones can be used as your main backup method and can also be instrumental in data recovery efforts by minimizing disk usage on a damaged drive. The tool can use the clone to enact data recovery functions or you can simply use it as a backup that is an exact copy of your original disk.
It may take a while, but eventually the process will end and you will now have a large DMG file that contains the contents of your hard drive. This clone can be used for data recovery operations, or simply stored as a backup of your machine. Another tool that you can use to create disk image clones is SuperDuper!. Recently a new method of backing up your computer has become available to individual users.
Remotely backing up to the cloud offers the user some advantages over more traditional backup methods.

If the disk you selected isn't formatted as required by Time Machine, you're prompted to erase the disk first. Click Erase to proceed. This erases all information on the backup disk. After you select a backup disk, Time Machine immediately begins making periodic backups—automatically and without further action by you. Time Machine backs up only the files that changed since the previous backup, so future backups will be faster.

Go to Security Options and check that the drive is set to overwrite past data at least three times. Time Machine will begin performing automatic backups, allowing you to retrieve any data from the moment the process started. Cloning lets you create a bootable copy of your hard drive for an extra layer of protection that you can fall back on if ever your Mac is out of action.
Local backups are quick and easy but, like your Mac, physical hard drives are susceptible to failure and catastrophes like flood, fire, or burglary.
