CentOS - Jan 2006 - date in logrotate

Quick logrotate question for the group. To comply with a PHB mandate,
I need to keep our apache logs for a minimum of 2 years, and will be
periodically required to hand over chunks of the logs from specific
dates/times. While extending the timeframe of logrotate is easy, I've
found that there's no elegant solution in the RH/CentOS logrotate for
appending dates to the filename. I'm curious to know what others with
similar requirements are doing for this. I'd like to stay within the
default system framework (no 3rd party apps as they have to be
"approved"), so mostly I'm looking for suggestions for a more
elegant
postrotate script.

Thanks

One approach is to use the /usr/sbin/rotatelogs program that is
supplied as part of apache.  You specify the logfile(s) as pipes
to rotatelogs in the httpd.conf file with parameters to specify
the base filename and interval to create new ones.  The files
are created with the timestamp as part of the filename - as opposed
to renaming them when rotating so it works well if you copy
with rsync but other handling might need changes.

I rotate logs daily using logrotate, gzip'd them and push
them to an independent collection system.  After 30 days, I
delete the local copies for local storage consideration.

That independent system puts them to two (2) DVD-R weekly.  I
also do any daily, weekly, monthly, day of week, day of
month, etc... log analysis on the independent system.

I use `date +%Y%m%d_%H%M%S` to add a date/timestamp to the
files.  You can do this directly in logrotate, or you can use
an independent program to do such.

It's very easy to setup such log rotation scripts.  My
centralized log collection system is typically also my main
backup server too.
