Rsync is a command-line tool usually used for synchronization between two systems but it can also become an interesting backup solution. It is a replacement for RCP (and SCP) with many other features. It uses the “rsync algorithm” providing a very fast method to synchronize remote files, which will allow, among other things, to make an efficient “mirror” of a file system. It does this by just sending file differences, without requiring the two sets of files to be present before at one end. This tool is relatively simple to use for anyone wishing to make backups of its system.

Key Features

  • On first use, rsync copied all the contents of the directories from the source to the destination.
  • rsync only transfers the modified blocks or bytes to the destination location, which has the consequence of making the transfer very fast.
  • During the transfer, rsync allows data encryption using the SSH protocol.
  • rsync compresses and decompresses (send/receive) data block by block.
  • It must be mentioned that there is no need for special privileges to install and run rsync.
