Does your computer need to restart after your computer is been backup?
In most cases, no you would not have to restart your computer
after backing it up. A backup is just an extra copy of your data
that your computer stores in another location. That way, if your
computer has problems or your data is deleted you can restore the
backup to retrieve your data. Creating a backup file does not
require you to restart your computer, since all the computer is
doing is copying your data to another location.
