[rdiff-backup-users] Local backup exception every other backup

[Jools Smyth]

I have a backup job which runs every day. However, it only succeeds every 
other day. After a successful run the following is output

Warning: Exception '[Errno 17] File 
exists: '/media/store2/aero-important-data/rdiff-backup-data/increments''
