I've been successfully using rsync's whole-file option to shuffle around
many rrd files for years with no issues. Same kind of scenario but with
Cricket. 5 data collection machines poll the data and update the files.
Every 30 minutes I the rsync the files to a central server for further
processing and aggregate display through the web GUI. Currently 32819
files and about 17Gb of data and have never seen an issue. I haven't
tested rsync's delta support with binary files but it makes me nervous
(probably unjustly).
