I hit ctrl-C and tried to launch it again and got these errors about locks.  Because I was using a remote repository, I found that I had to issue the break-lock command on both computers before I could run my backup again.

My advice would be to not back up 2TB at one time, especially for the 
first backup. I would use:

http://borgbackup.readthedocs.io/en/stable/usage.html#borg-create

PATH                  paths to archive

to feed it smaller portions at a time. In fact if it where me and 
depending on what you are backing up I would probably break the backup 
into smaller repos.
