Recomended config for iMac, Time Machine and time Capsule
 

Subject just about sums it up - I'd like some recommendations for the best config for this.

Best config? Not really sure what you mean...

Sorry, missed your reply and didn't have thread subscription on :(
I'm using TM and TC - I thought I'd read something about how best to use SD in this scenario? From your reply I guess you'll say - just backup as usual, but I don't really need SD to backup all my files now. But I would like some form of bootable backup.

You really need to use "Backup - all files" to get an effective bootable backup. Time Machine & SD! are covered in the FAQ forum...

thank you, i've read that.
