This video is the continuation of creating an RSYNC script. It familiarizes a user to the different options and syntax of RSYNC. Finally we run CRONTAB.
One more benefit of using an RSYNC is that ONCE you've got a COPY of ALL your files in your Backup Hard Disk, it will just look for DIFFERENCES in the Source, and once it doesn't find it in the Destination, it will just COPY, the Few Missing Files.
So you don't have to backup the WHOLE COMPUTER once again. It's also called Incremental Backing Up of your Files.
