   So.
   I need help from bash wizards.
   I need a command that I can use to backup shit.
   What I want it to do:
   Check content of target folder1 recursively and compare it with the content of a target folder2, again recursively.
   
   If the target folder2 has a file that doesn't exists in the folder1 the file is removed.
   If folder1 has a file that folder2 doesn't have, it gets created, this includes folders
   If folder2 and folder1 have a file with the same name but the file is not the same (difference in size or whatever) then the file in folder 2 is replaced by a copy of what is in folder1
   
   I would like the process to be possible to interrupt at any moment and to start it again whenever without fucking it up.
   
   What can I do to achieve this?

     I'd recommend rsync for that usecase too, it's simpler.

     @raccoon rsync, then. That's what I usually use for that type of operation. However, rclone sync will do pretty much the same thing. It works on a local backup scheme, too, if you set up the endpoint correctly...

     Thanks Brian, I looked it up, neat project and I actually may have uses for it, but not for the specific thing I have in mind now.
     The main use for this would be keeping a backup of a 4TB drive to another 4TB drive in case on of the two failed :P

     @raccoon rclone is one option.

     If you want it done in the background, read the manual so you know what command you wanna use then just setup a cron/anacron job that runs it every day or however often you want. I do it like that for some of my own stuff.

     @dushman @raccoon Yeah, I do that with rclone and AWS. Although, I think I'm going to switch to restic with a rclone backend...
