Yeah I use Linux and am comfortable with command line.
I am not looking for continuous backup though. I would occasionally add stuff to backup - like every few months or so. I also want the incremental backup part - not sure if encrypting backed up data using luks would allow incremental addition later on.
I will check rsync and luks. If you have any resources, please feel free to post here.
This would require me to have a ZFS partition first and transfer my data on it, right?
Right now I am not using ZFS, but for next OS reinstall, I might try it. Thank you.
