have not yet played with time machine, and i cannot quite find the answer to this: can i use time machine on my mac pro to backup 2 separate drives at once? by this i mean i have 3 drives: drive1: boot disk, with library, emails, iCal calendars, applications, itunes music, etc. (320GB) drive2: documents and archive of work (750GB) drive3: intended to be used as time machine drive (750GB) so how can i back up BOTH drive2 with all the documents, and drive1 with all my emails, calendar items, etc. with time machine? i assume TM will not allow me to do both drives at once, so would i need to make drive3 into 2 partitions, one for drive2 backup and one for drive3 backup? can i make TM do two backups like that? any ideas? thanks!
