On an old 2008 iMac running 10.5.8, my colleague has a business that relies on her computer six days a week.  She has Time Machine outputting to a 500 GB external drive, yet her internal drive contains only 120 GB.  The Time Machine data base goes back to 2008 and occupies over 400 GB.


I would like to partition the external drive to hold a copy of her system (now on the internal drive), for use in case the internal drive fails.  However, the Time Machine data base is too big.  Is there a way to prune the data base to make it smaller?    She would like to keep some backups back to 2008 if that is practical.


I see that the data base is made up of dozens of dated files.  I'm tempted to simply delete a bunch of them, but I have read on these pages here that Time Machine gets fussy about that.  I'm afraid that deleting a bunch of files would ruin her backups back to 2008.


What would you suggest?
