The online university where I study is constantly experiencing data loss, including students’ files and literature, so I want to recommend them an effective solution.

  • @Alvar... maybe, let's see... Elizabet, what are your requirements? Is this just a personal solution or for a number of students?? How are the files stored??? Please elaborate... – Jason R. Mick Nov 4 '13 at 8:40

Supposing that you are using Linux in your system, in the scenario presented the best would be a userless solution. I would do it using a backup server (simple fileserver, nothing fancy), and rsync over ssh. The rsync would run from cron.

Steps: Set up ssh keys (to can use cron passwordless):

cd ~/.ssh  
ssh-keygen -t dsa
ssh-copy-id -i ~/.ssh/id_dsa.pub user@yourserver.com  

Test it with ssh user@yourserver.com. It sould not require a password anymore. Now you can use the rsync -atvz ~/local-directory/ user@youserver.com:remote-directory/ command in crontab.
