Files Back-up

Lately, I have been noticing some malfunctions in my laptop. There is always an error, most of the time it hangs and it no longer shuts down properly. With these, I think I need to perform back-up of files either through cd and cd duplication to make the files personally available. I can also ask one of our IT personnel to do the same thing saving my data in a designated server.It is better to have options than being so regretful of losing working files. It would create a personal chaos and will even consume much time to make some rework on the reports.
