Linux Lite 4.0 Suggestions welcomed

Users replace "username" with their user name.

Code:

tar -cvf backup.tar /home/username

This creates a tar file named backup.tar that will backup all the contents of home/username folder and the sub directories.
It gives the verbose output to terminal during the process from the v option.
I seen it last week a few pages back, in the book "Linux Bible".

It has some potential for tweaks, like no verbose but output to log file that.
If gui that has a button reading eg; "backup-now" attached to this command, clicking that button so  would make a Lite, fast, and efficient backup.
Somewhere (maybe online) I cannot find it at the moment, I seen a command to output to USB results of commands. Attaching that to the export to usb button in GUi.

The other backup areas such as full OS, then maybe like machine type freeze/shot as an iso I am not sure this yet. Similar as can be done with Python apps for distribution, where it each machine state downloads "its" specific requirement, this can be where drivers differ and dependencies.<< makes the backup size lightweight/smaller and faster/more efficient.
Executing this is like the button to use the system rollback/restore.

I think the idea of it has potential of a seed to become "Lite backup" of future.
