I've setup a new mirror (almost finished) but I have a few questions.

I am running the first sync as a single command right now, sync'ed weekly until I get a few questions answered.

Currently, my command is:

rsync -aqzH --delete --delay-updates us-msync.centos.org::CentOS /var/www/centos

I plan on just allowing http for now, and I'm connected via multi-homed DS3's so bandwidth is not a HUGE problem. I am not limited but might have to if the link becomes very heavily used.

My questions are:

If I am to sync 2-4 times a day, how do I setup lock files in a script?

Right now i'm just using a single command (listed above). I assume you will most likely tell me to connect to a Tier 1 server to sync from instead of a master server right?

Secondly, if I were to say drop down to only version 5, what is the best way to do that as well?

Thanks,

Josh
