Question: Copy Time Machine or Start New?
Looking to understand if I should copy the existing TM backup files, or start a fresh new backup on the new disk.
I'm replacing the external drive on my iMac that has been used for TM backups with a new and larger unit.
Would appreciate your thoughts on pros and cons of:
A) starting a fresh TM backup on new drive; holding the old drive for a period to ensure prior files not needed
B) copying over the TM backup files from the old disk drive
My TM backup archive is extremely large -- this is a mid-2010 iMac and the TM backups have consumed 995GB of a 1TB partition.
Full Disclosure: I followed Apples method to copy the old TM backup to new drive, and after 15 hours, Finder was in the "preparation" phase and had not started copying any files. I stopped the copy as this got me thinking if I really needed to retain this much "old archive". In the seven years I've used the Mac, I've never had reason to go back and grab a file from TM backup.
Comments greatly appreciated.
iMac, macOS Sierra (10.12.6)
