Time Machine advice - thanks
Friends, from time to time (like this morning), I find that Time Machine on various Macs around the house seems to "start at the beginning" or do what would be a major backup as opposed to just an incremental on what changed. For example, this morning, my wife's new MBP (month old) started TM on a 12GB backup, basically the entire disk.
TM has been working (successfully it would appear) on this machine since day 1. Does anyone know why TM would do this and is this normal?
thanks much, Paul
