I found my repository grows up soon recently. After checking all possible case I found if I modify the large file (the installer file which size about 2.5GB) and commit change to svn server.My repository size grew up about 2.5GB. we can't save binary diff to server, what happened to me? need ur help.
ps.we have a daily schedule build installer job,now we stop the job to reduce the modify update installer job untill we can figure out the size of repository.
