Backup failed, resumption scheduled, site with HUGE uploads folder

Hi,

I’m attempting to use Updraftplus to back up a client site with an absolutely enormous uploads folder (mainly because they insist on having the capacity to upload their HD images in full resolution!) – the total site size is 3GB and almost all of that is the uploads folder. The initial backup last night failed at the uploads folder but I can’t make head or tail of the log file – it’s here https://gist.github.com/emmawinston/ef0b22e635ce1dd98613. Should I just let it resume?

Can anyone suggest anything?
