As I get ready to make the switch, my concern has been that with about 200 people working on the site and some parts of the site updated several times a day, I am concerned about the issues of keeping a mirrored copy current while the domain name change gets routed through all the nameservers. There is about 250MB / 20,000 files on this site getting about 4,000 visitors / day. In addition to the regular html pages getting updated, there are a number of CGI and C programs writing data that needs to be kept current as well (ie, voting polls, counters, ad banner logs and stats, etc..). I have recently run across rsync when searching for a solution to this problem and was wondering if anyone has been using it in this type of fashion to keep the data consistent across the two machines and what your comments are on it's performance for doing mirroring? Ideally, I would like to have it run about every 30 minutes since it appears to only update the changed data. Any ideas on what kind of a load this would put on the server? I only expect to use rsync for about two weeks for the mirroring job. Afterwards, however, I can see how this can be an extemely useful tool for maintaining an additional backup copy of the entire site (and I assume the entire hard drive).
