i've been using synk pro to backup my mac since...forever. all i want is an identical mirror of my mac at any given moment; i don't need time machine's endless versions of files, etc. i take responsibility for this, i just want my mac mirrored. i use synk pro to do the same thing for two external drives. this has all worked pretty well for years. but had a crisis with the app recently, and tech support has been sketchy about it. so...can CCC, or superduper (for example) do this for me? mirror my mac drive, and several external drives? or is there another app to recommend? thanx!
