Backing up your files

Have you?  Think of it like a tetanus shot.  If you can’t remember the last time then you’re due.  Doing a single data backup from the servers for 3000 people takes almost ninety contiguous hours and obviously things change in that amount of time.  Play it safe.

Storage on the school network is a tool of convenience.  Keep a backup copy of all important data in al least two different locations.  Only you are responsible for your data.
