I have an old rig that I am trying to 1) learn linux and terminal/bash 2) make it into a simple fileserver so that I can mirror my documents through LAN. More specifically I will be using it in an office environment so I can not use Dropbox for example since it goes through their servers (my files are very confidential).
So I would like dropbox like functionality where a file change on my business machine (windows 8) is mirrored to an ubuntu box. Actually I am okay with periodic backup also rather then as soon as I hit "ctrl s" it starts a backup - this actually might not be a good idea considering the harddrives are slow and old and running them a lot is just asking for problems and failure.
Please let me know the easiest root with possible instructions.
EDIT: I think what I am looking for is Samba. After I install samba it will give me a readable/writable folder on my linux machine. I will be able to access this location through explorer in windows.
My next question is: does there exist a backup software that I can manually type in the folder location?
EDIT 2: I believe that syncing to the cloud is also possible as long as the files are being encrypted before they are sent. Any way to incorporate this ? Thanks
