Backing up log file

I am trying to have rclone back up its log file on Windows Server 2008.

This is my command:
c:\scripts\rclone\rclone.exe sync I:\ corp:bloomsburg --config=C:\Users\Administrator.config\rclone\rclone.conf --log-file=i:\sshlog.txt --log-level INFO --exclude “/System Volume Information/**”

This is the log file:

Unfortunately the log file changes size while rclone is running so rclone can’t back it up. You will have to exclude it from the sync I think.
