Mysqldump all databases and gzip

So, quick and simple MySQL backup in a CRON.

_hour=`date '+%H'`;
mysqldump -u $_user -p$_pass --all-databases --ignore-table=mysql.event | gzip > $_dest_$_hour.sql.gz

I’ve used this in an hourly CRON so that I always have 24 hours of backups.

Note: The ignore of mysql.event is to stop an annoying new feature of a later version of MySQL that seems to report a notice that its skipped this table. I don’t really need it so I am ignoring it.
