• A strategy in which data is copied from one Server to another. This ensures that an exact replica of the data is maintained on different servers
  • rsync is a common tool used for server mirroring


If one server is down, the other server can still serve the data.


We can have servers in different geographical locations, users can access data from servers that are closer to them. Thus, better performance.

Package Mirror


For Pacman, the default package mirror can be very slow. You can run sudo pacman-mirrors --fasttrack which update the mirror list with the best package mirrors based on their synchronization status and connection speed. The mirror list can be accessed via cat /etc/pacman.d/mirrorlist.

It is recommended to run sudo pacman -Syuu to update and upgrade the system after updating the mirror list.
