Little-known indeed--I didn't know rsync could do that.. that's really cool.
So for a little more explanation, say you have a directory tree /database,
and you want to sync only the files that were changed in the last ten days.
You should be able to do something like the following:
rsync -av REMOTEHOST:'$(find /database -ctime -10)' /local/database/mirror
which would be about the same as
rsync -av REMOTEHOST:'$(find /database -not -ctime +10)'
/local/database/mirror
The difference between using find's ctime and mtime options: mtime will only
change if the actual file data has changed, whereas ctime includes both file
data and metadata--permissions, ownership info, file name, etc.
Hope that helps!
