This morning I tried redo just as a project against macrium which I use on all my machines.
Redo is a linux based live cd, so it cannot be used within windows, it needs to be booted from your ODD.
redo took some time to load but every option for backup was available.
I successfully backed up my C partition (200gb), but it took 98 minutes to do this. Because you are doing this 'offline' this is 98 minutes of downtime so for everyday use is extremely time consuming, whereas macrium from within windows takes 20 mins on my 200gb partition and you can continue to work.
So Macrium gets many more stars and using whs's PE recovery link, a restore is so easy.
Basically Macrium beats redo for everyday use because you can invoke from the desktop at any time.
One area where redo may be an advantage is where you 'clean' a new pc of the crapware, install what you want for starters, security, minimal apps, no data stored etc.
Pretty useful for resale in the future perhaps with a default system.
