I'm looking into setting up a portable external drive that will contain a backup of my documents and images. I plan on backing it up daily/weekly. I see I can use rsync to copy the images over but I stumbled upon chronosync which has more flexibility and power at least in terms of having everything upfront easier to use. Any opinions on one or the other? The goal is to use this small hard drive as an offline backup that I'll keep at my office so that if anything happens to my home setup, my data will still be safe.
