Keeping old /var/log/messages

Hi,

Sometimes my laptop freezes, and I have to shutdown with the power button. I would like to investigate the problem,  but when I boot again the old /var/log/messages is replaced by the new one. Is there a way to keep old versions, just as it is for /var/log/boot.log?

Thanks.

edit: this is a harddisk install!

Previous messages file is saved as messages.0

Re: Keeping old /var/log/messages

You are right. But one level of backup is not enough, because /var/log/messages is flooded by those udev errors.

For example, today there remains only 19 lines of my previous session messages in messages.0 . The remaining 708 are from today (as well as all 700+ lines of /var/log/messages).

So I'd need either a means to keep more incremental backups, or a means to filter out udev errors before they reach the log. Or both!

Thanks in advance for any hint or solution.

sed -i 's/SYSLOGD_ROTATED_SIZE=.*/SYSLOGD_ROTATED_SIZE="4096 -b 50"/' /etc/rcS.conf

Thanks a lot! 50 might be too much though ;-)
