 **rsync** //(or **remote sync**)// is a [[tools:bash|command line]] utility for transferring and synchronizing files between any given //"source"// and //"destination"// pair. It is extremely popular for use in backup utilities, at it can synchronize backups between not only local filesystems, but also over the internet via [[tools:ssh|SSH]]. **rsync** //(or **remote sync**)// is a [[tools:bash|command line]] utility for transferring and synchronizing files between any given //"source"// and //"destination"// pair.

-While you can technically use the ''cp -R'' command to make quick and dirty backups, ''rsync'' offers far more flexibility for common real-world scenarios.+While you can technically use the ''cp -R'' command to make quick and dirty backups, ''rsync'' offers far more flexibility for many common real-world scenarios.
  
 If you are already familiar with using [[tools:wget|Wget]] to make mirrors of entire websites, then use of ''rsync'' should come to you pretty naturally - it just operates over local filesystems & SSH instead of HTTP/HTTPS/FTP. If you are already familiar with using [[tools:wget|Wget]] to make mirrors of entire websites, then use of ''rsync'' should come to you pretty naturally - it just operates over local filesystems & SSH instead of HTTP/HTTPS/FTP.

 In the case of both of these commands, //"local shell"// just means whatever terminal you are running ''rsync'' from.

And no, you cannot use ''rsync'' between a remote source and remote destination at the same time:
  
-  $ rsync -avz -e ssh user@remote:/source/directory/ user@remote:/destination/directory/+  $ rsync -avz -e ssh user@remote1:/source/directory/ user@remote2:/destination/directory/
   The source and destination cannot both be remote.   The source and destination cannot both be remote.

-One more clarification: If you are running this from a remote machine, that machine is the "local shell" in this equation, and whatever machine it is SSH'ing into is the "remote shell." Make sense? Good, because there's a few more things you have to grasp with this command, or you're going to make an absolute mess of your files.+So if you want to sync between two remote machines, you will have to first SSH into one of them and run ''rsync'' from there "locally" with the other machine as the remote.
