Theoretically, yes, but it also depends on the speed of the drive inside the router. It shouldn't be that much faster than backing up over N, but I'm not very well versed in router speeds and such. Interested to know myself actually!
) to get it to back up. Now the external is hooked to a AC time capsule. How I managed to fill 3TB is beyond me... I don't usually notice the time though. But I think (havn't thought about it in a long while, which is nice) it takes around 3 hours to backup all the changes I make to my 1TB drive daily.
I have a frankenstein setup here, used to be a standard Airport Extreme with an external drive attached and some weird terminal hacking on my end (googled it!
Depends on what I do... I think 3 hours was after I moved around 50gb of files around. Now that I think about it some more, I really don't know. I don't think I've timed it in a loooong while. I do remember it would go pretty fast (15-30min) for some backups, and 3 hours for others. Maybe it doesn't back up while closed (likely) and condenses 10 hours of backups into one.
Dang it man, now you've got me troubleshooting my system again!
