here is mine. runs through a cron job.
It creates SEVERAL backups, because often there is a corruption and it already is in 1-2 backups before I discover it. I back up every 12 hours
[root@a3p mario]# crontab -l
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.7136 installed on Sun Jul 7 09:50:34 2002)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
28 */12 * * * /root/cron/cron_mysqlbackup
[root@a3p mario]#
If you have passwords, of course, add the passwords
Note the NICE!!
Question:
what happens to writes during backup? mysql can back up for half an hour during writes? If it blocks the database, I might as well remove the nice..
