I have a MacBook Pro with 3TB of files/apps/data.
I want to do the 3-2-1 backup. 3x backups, 2x onsite and 1x offsite.
I have a local 4TB external hard drive and a ‘NAS’ “4TB WD MyCloud” as my onsite backups (using TimeMachine) and want to sync/copy the onsite NAS “WD MyCloud” to an off-site cloud service (ie iDrive).
Where can I find out how to do this please.
