[XCSSA] Rsync usage

[X-otic Computer Systems of San Antonio]

Hi everyone,

I know some people on this list are familiar with rsync, and I'm
searching for some information.

I'm using rsync to sync directories on two different servers.  The files
in the directories currently total about 1.8Gig of space.  And I'd like
to keep about seven days of incremental backups on the backup server.

But on the second (backup) server, I'm trying to conserve disk space. 
Right now, I have a script duplicate Monday's backups to Tuesday and
then rsync runs against Tuesday's copy.  Of course, it duplicates
anything changed on the main server to the backup server.  But that
means that a lot of files not changed on the main server are also in the
new day's directory on the backup server.  And that's where the disk
space is being eaten up!

I'd like to find a way to get rsync to compare directories and copy the
changed files to a different  subdirectory on the backup server.  Does
anyone know how to do this with rsync?  Or am I stuck with a secondary
script deleting any unchanged file in the new day's backup folder???



Chuck
