OK /prog/ what do you use for backing up your systems? like, entire systems that you can easily restore from?

I use this, but im think surely there is a better way :s

if [ -d "$1" ];
then
sudo rsync -aAXv --progress --exclude={"/files/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found","/home/*/.cache/*","/home/*/Sync/*","/home/*/.mozilla/*"} / "$1";
else
echo $'usage:\n'$0' </path/to/target/directory>';
echo $'\nError: invalid target directory, cancelling backup..';
fi

An hard drive.

I drag the directories I want to keep onto an external drive. Much easier than messing around in the command line.

I use a 128gb usb stick.

I just store my stuff on the cloud.
