Can someone pls give me some advice on best backup options for backing
up the songs on a Pro Tools 5.1 Apple G4 9.0

From the point of view of the studio would it be best to have some
sort of external hard disk storage system - that can be stored
elsewhere for security ??


Secondly for artists that would like a copy of their song data - would
a DVD burner be the best option??

Any advice or recommendations of equipment would be gratefully
recieved

Thanks

Rob
