Lost files

I am surprised to find out that the University as a big organisation with important student information does not have a backup. My files went missing from my u-drive and then when I asked for help I was told that there is no back to retireve my files.
Please find a way that can be helpful to students.
The company running the IT facilities for this Uni must have a data back up system


Thank you for your comments. Looking at your circumstances I have to tell you that the files you "lost" were never saved in the first place. Your network space was full when to you tried to save the files and therefore the items are lost and irretrievable. Data back up would not help you in these circumstances.
Every student has a 100 mgb allowance on the University's network. As your network space was full you should have deleted some files/folders or archived some older material on a USB at the time. As a Computer Networking student I am sure you are aware that although you may have created space after you tried to save the files they do not get stored in a strange "cache" in case of this eventuality.
Please may I encourage you to carry out regular house keeping on your network space to avoid this happening again.
