Make sure you are not using meta characters in ways the hurt you.
Commonly \ is used to escape the next character.
In windowZ  the \ is used as a file separator.
Same is true of dots '.' which matches any single character.
Spaces are a bugger in file names too.

Now I wonder if you intended to build a directory tree:
with the format  messages_yy/mm/dd/_hour/minute

I have not tried this but I suspect your logrotate configuration file
could have a postrotate line that in addition to sending a signal to
the process did something like:

	mv logfile.1 logfile-ending-on-`date +"%Y-%m-%d_%R`

This will cause side effects.  You are no longer rotating the files.
If you only want 28/29/30/31 files a month then you need log.1 log.2
...log.31. type stuff.

i.e. Now you can run out of space which logrotate is to avoid.

Compressed files are good, make sure the compression suffix hint is
not lost.
