You could find these files using find. Then, copy these to another

If you were cleaver you could hard link the files to save space before the
sync. But maybe someone on this list will know how to do this with just
rsync.
This is just one possiblity. Maybe somone has already written a tool to do
the first step.
This is rather similar to what I'm currently doing via a (shell)
script which uses rsync. I have several servers that get backed up
every night, using a combination of hard links and multi-day retention.
Basically, let's say I want to keep a 7 day backup on a server, the
nightly process runs as follows:
1. delete the oldest backup (.7)
2. Increment all the other backups +1
(.6 -> .7, .5 -> .6, .4 -> .5, .3 -> .4, and .2 -> .3)
3. Create a hard link between .1 -> .2
4. Run rsync from the source into .1
So if a file disappears from the source, it still exists in backup
for another 6 days after that night's backup. After that, it gets deleted.
This process allows me to backup 15 different servers to one single
terabyte drive and keep 4 weeks worth of backup for each. (NOTE: I'm
not backing up 100% of each server's content, just things like /etc,
/home, /var/www, /var/mail and the like.)
