A quick Google didn’t turn up anything or verifying MySQL database dumps, but that doesn’t mean it’s not possible…

Nice scripts.
I mostly use FrontBase, and it allows you to check it’s catalog file for the validity / integrity of the dump. so i basically make a backup of the db to a file in a directory nonverifiedbackups. then run a FBListContents on the file. if it is invalid an email is sent to the admin. if it isn’t it is moved to a directory verified backups.
i’m not sure how to make the code frame above, i’ll send the script on request.

Here is what I run on my servers:

#!/bin/sh
# mysqlback.sh -- do mysql database dumps -- t| ########################
PATH=/usr/local/bin:$PATH
BACKDIR=/usr/local/mysql/backups
DAYSBACK=7
export PATH BACKDIR DAYSBACK
########################
# clean up backups older
# than $DAYSBACK
########################
cd $BACKDIR
find . -mtime +$DAYSBACK -exec rm -f {} \;
#########################
# get a list of databases
#########################
cat < tmpsql$$
show databases;
EOF
/usr/local/mysql/bin/mysql -u root --password=******* < tmpsql$$ | sed '/Database/d' > dblist$$
#########################
# back each one up in turn;
# --opt locks tables during
# backup, so no need to shut
# down mysql; but access will
# be denied during backup
#
# we also pipe through gzip
#########################
for DB in `cat dblist$$`
do /usr/local/mysql/bin/mysqldump -u root --password=******** --opt --flush-logs $DB | gzip > $DB.`date '+%m.%d.%y'`.gz
done
###################
# empty the logfile
###################
rm /usr/local/mysql/logs/mysql.log.*
cat /dev/null > /usr/local/mysql/logs/mysql.log

#######
# email
#######
ls -l $BACKDIR | /usr/bin/mail -s "MySQL Backup Completed" user@domain
##########
# clean up
##########
rm dblist$$ tmpsql$$


Not sure how it compares.

On my Xserve I run this script along with a script to tar the WebServer directory. The script then tars the MySQL backup directory and sftps both tar files to a server which is backed up to a SAN. I think you discovered the sftp using key pairs in an earlier post. I’d known about that for a while. It was on O’Reilly a few years ago (well the key pair thing for SSHwas) and that is how I have secured SSH on my servers. I actually require a password to use the key when doing SSH so that no one could login even if they got my laptop (which is the only machine that can login to the server).

If there is anything else your trying to do let me know. I may have a few more tricks up my sleeve (mostly borrowed from scripts found by googling or on OS X Hints).
