It can hardly be considered a backup if it's easily compromised from your every day computer. In a good backup configuration your computer only have read and "append only" privilages for the backup so past snapshots are safe.

Having said that not many people have this kind of config (including me).

Not sure why you're being downvoted, you make a very valid point.

I guess it's because this kind of backup doesn't mitigate an ongoing compromise of your machine (much like what the GP talked about). I don't think any backup can protect for that. However a good backup limits the damage to the timeframe of the machine being compromised (if your machine is compromised for 1 day you might only lose that day's new data).
