This module will begin in the terminal window by installing the software to synchronize the data. First type the code shown here and then press Enter. Once the program is installed, users will need to copy the files from usbhdd1 to usbhdd2 using the second code. This will open the nano editor, scroll down to the bottom of the document and enter the following lines of code 3 and 4. This command specifies that every day at 5:00AM (the 0 5 part), every single day (* * *, wild cards in the year, month, day spots), the user wants rsync to compare the two directories, copying everything from HDD1 to HDD2 and deleting anything in the backup directory that no longer matches something in the primary directory—i.e. if the user has a movie file on HDD1 it is deleted, that file will also be removed from the backup on the next synchronization.
