Save the script and run it as a cron job:
@daily /path/to/yourmysql.sh
This is a really nice script although I did some changes for it, nothing major:
– Commented the CHOWN. For some reason is was doing a root wide CHOWN, being that I am not running the backups as root, I do not need to CHOWN the files anyway, they’ll be owned by the administrative account.
– I had to add the list of databases that I wanted not to back up, I though that just adding the ones that I wanted would exclude the ones that I did not wanted to.
But, it is a very handy script and I appreciate you posting it. Thanks.
