This wasn't my intension, i am sorry!
The longest wait i had for a filetransfer to end, was when i backed up my music collection (1,4TB at that time), to my personal cloud.
Since Germany still hasn't the best internet infrastructure compared to other countrys (thanks, civil engineering law), i had a 50/10Mbit VDSL connection at that time.
I could not saturate the 10Mbit upstream, else the bufferbload would kill the internet.
It took me 2 weeks to finish the upload, only to get even more music, but fortunately i have a 100/40Mbit VDSL connection now.
