Rsync-incr has been updated to version 1.6. New in this version:
old backup removal was not working if the destination was on NFS, fixed. Note that backuping to NFS is not a good idea as it is quite slower than local disks, this was why it was an untested case up to now.
new --no option to only clean old backups to make room for the new ones, but not actually performing the backups
