To follow up on this... I found the --stats option and
here's what I'm getting:
Number of files: 36
Number of files transferred: 36
Total file size: 10200816 bytes
Total transferred file size: 10200816 bytes
Literal data: 10200816 bytes
Matched data: 0 bytes
File list size: 576
Total bytes written: 10203996
Total bytes read: 596
So, I don't know why no parts of the files are
matching. The files are the same save for 1 or 2
values changing every 5 minutes. I don't know if
anyone here is familiar with RRD files, but they're
database files commonly used for SNMP data collection.
All the fields are created initially so the file size
never changes -- the fields are populated as time goes
