How to do a New Full Backup with Time Machine
Hi All,
I'm using Time Machine with it since 3 years but I strongly suspect that I've compromised my backups integrity since I've deleted some of these manually in the past, so now I cannot trust more these backups.
As far as I know, Time Machine works with incremental backup so what I would like to know is how I can redo a new entire backup from scratch of my MacBook pro?
I'm on Mac OS Sierra 10.12.6 right now and I would like to update to Catalina (I can't update to latest OS version due to HW compatibility issue with some devices I have) and before do that I would like to have a full complete reliable backup of my machine, also in case in the future I'll need to downgrade the OS back from Catalina to Sierra.
Any help we'll be really appreciated.
Many thanks!
MacBook Pro 13″, macOS 10.12
