Hello. I am backing up my external drives using Time Machine on my Imac 10.7.5. Now I need to restore backups of my my 2 external USB harddrives (each one has 1TB) onto a brand new 3TB USB drive. I cannot just copy from the original drives, because some files have been accidentally deleted in the past few months. I need to do a full restore of backups made 6 months ago. Do not feel like spending hours trying to figure out which files are missing. It seems easier just to do a full restore. Is there an option in the restore process that allows you to restore to a different drive than the original drive and to merge the contents of 2 backed up drives onto a larger new one? Also: how long does it take to restore 1TB of data? Is it hours or days perhaps? I would like to know this before i even start. Thanks in advance for any info.
