The source drive currently has about 250 GB of data on it.
I want to mirror it using the WD - supplied drive backup software Acronis true Image.
I know this will be a rubbery figure, but is it 1 hour to mirror to a second drive or 10 hours?
Also, what happens if , for instance, I have a TV recording scheduled for within the backup time? Will it interfere/be interfered with by the back up proces?
Thanks for any help
