[CentOS] Backups on external USB HDD

[Alain Spineux]

This is autofs package

       The  automount  program is used to configure a mount point for autofs,
       the inlined Linux automounter.   automount  works  by  taking  a  base
       mount-point  and  map  file,  and  using  these  (combined  with other
       options) to automatically mount filesystems  within  the  base  mount-
       point  when  they  are  accessed in any way.  The filesystems are then
       autounmounted after a period of inactivity.
