I've set up my laptop to do a mirror backup wirelessly to a network drive. The initial backup took a number of days to finish. Following backups are quick enough.
I'm wanting to do the same thing on my wife's laptop, but don't really want to have it taking days for that initial backup.
If I was to run the initial backup with the drive plugged directly into the laptop via USB, do you think any subsequent backups would recognise that it's the same backup, and just mirror? Or would it think it's a whole new backup and start again?
