hmmm..... now i've been asked to build a few networks, with a few dedicated render rigs. So far, i've only been asked to put on paper what would be needed. And i've yet to figure out what or how to do backups.
Orginally my plan was to simply build each rig with a raid aray, setting 2 hardrives with Mirror mode, i figured this would do plenty good enough for a client machine backup protection.
Then setup the dedicated servers that the client machine could selectively backup thier data they wish to make sure to keep safe to a drive. I thought this would keep the amount of hardrive space storage down to a minimum, keep things generally quite clean with say, every month going through it and weeding some of the crap out manually.
Then again, i'm not dealling with probably hundreds of clients

..... i think i'm dealing with tops, 15 clients with 4 Massive dedicated servers, 3 of which would be render "pigs"
