Problem: I have two NAS servers, both running Debian, located on two different addresses. Each has an album of pictures, which are both several 100gb.
What i would like is to set up a secure backup function that backs up the pictures on one NAS to the other one, and vice versa.
I was wondering if anyone knows of a program which can do this out of the box which i can install and use without too much hassle.
Traffic must be encrypted
Must only back-up the file once pr change (Should remember or check which files are backed up)
It would also be nice if it could be started and stopped so it only runs during the night time.
If anyone knows of such a program, then i would very much like to know. I have stared myself blind googling for hours.
