My last backup external drive quit.  It has been about a year or so.   I have changed some of the data on my Mac,  and deleted some too in that time.

 

Q.   Now I am ready to backup again with an external drive.   Will Time Machine revert back to the old data or will it begin with my iMac data that I have now?

I prefer for Time Machine to begin from today's data,  not what it was with the previous backup.   If this makes sense - is there something I need to do?

 

Thanks.

    If you are starting with a new external disk, TimeMachine will start from scratch.  First making a complete copy of your boot drive, then as you change files, it will update the backup with those changes (checking once an hour).

     

    You old backup is on the previous external drive you said quit, so that data is most likely lost.
