I have just moved the backup from a small NAS drive with a samba server to an ubuntu box with openssh and the slow backup problem seems to be solved. I can now backup at about 1MB/sec over wifi and one of the two cores tops at 100% usage.
This suggests that the problems is due to backing up on a samba share.
