I therefore look at my planned approach and think " I benefit from redundancy, and because I use Time Machine I have multiple versions of each backup, so why can't or shouldn't I use RAID-1 for backup?". I say this because with RAID-1 I get desirable redundancy protection from drive failures (up to a point, naturally), and as I use Time Machine I inherently benefit from the ability to pick and choose from historical backups. In considering the above I've been researching opinions about RAID-1, and in doing this have seen a lot of opinions stating "RAID isn't backup", "never use RAID for backup" and "deleting files from your drive or being infected with a virus will replicate to the RAID with no roll-back", yet when I consider my strategy above - and bearing in mind for a moment that the RAID drive will only be used for Time Machine backup/restore - I feel like these comments don't apply to my planned configuration.

For the time being I have continued to use the external HDD for my iMac Time Machine backup, however as this drive is only 1TB it's no longer suitable as a backup target (or at least, the time will soon come where it is not suitable due to lack of space). Recently I purchased an iMac Pro with an internal 2TB SSD and restored my system from an external 1TB HDD Time Machine backup as originally created by my old MBP.
