I am helping a group of people open up a new elementary charter school here in NH and we will be Mac based. I will have: 15 macbooks- five with DVD superdrives 1 airport extreme base HP all in one printer/fax/scanner The teachers will be taking digital video on a JVC HD video camera, taking plenty of digital pics, etc so I will want to devise a simple solution to back up all the video data not to mention all the word/powerpoint/excel files that will be created by students, teachers, and administration. I am the volunteer tech person and am fine setting up everything for the wireless through aiport and maintaining the macs. How can I easily back up data from all 15 macbooks automatically. I don't want to have to manually back them up as I won't be working at the school except to do basic maintenance. What are my options. Please recommend different options of varrying costs please. However, I have quite a bit of grant funding if necessary to pay for a system that will automatically backup all those computers easily.
