This is not the same as a full Time Machine Backup, but a super awesome feature of the Time Machine Backup Utility that allows a restore with ease. This does not require you to have an external drive for a Time Machine Backup.
We will perform the following:
Create LocalSnapshot (This does not require a lot of space as it is not a backup of your files)
Restore from the Time Machine Backup LocalSnapshot
Automate our Time Machine LocalSnapshots, so we have one done in the morning and at night.
This works on:
Mac OS Catalina
Mac OS Mojave
Mac OS High Sierra
Can be used to save your butt when:
Mac OS Updates Fail.
To uninstall an app you just installed and decide you don't want.
You accidentally deleted files and need them back.
You made some unnecessary changes to a file and want to revert.
