cut-off time for rsync ?

It takes hours to traverse all these directories with loads of small
files on the backup server.  That is the limiting factor.  Not
even copying: just checking the timestamp and size of the old copies.

The source server is the actual live system, which has fast disks,
so I can afford to move the burden to the source side, using the find
utility to select homes that have been touched recently and using
rsync only on these.

But it would be nice if a clever invocation of rsync could remove the
extra burden entirely.
