We have an rsync job that copies thousands of tiny little files to a server. After the files are on that server, we use retrospect to back them up to tape. Retrospect is starting to choke due to the large number of little files. I'm looking for a way to archive the files after the rsync so retrospect only has to dump one file to tape. I don't want to tar all the files everyday as that just adds to much stress to the disk and we may miss our backup window. After the backup is done, rsync will need to run again, but I don't want it to copy every file back, so it will need to be able to view all the files before update.
