MysqlHotCopy backup script

[kontrabass]

I'm looking for a backup solution that will:

- shut down forums with a custom 'backup in progress' message

- execute mysqlhotcopy to backup specified DB's to specified dir

- roll over backups to keep only x number backups on file

- reopen forums

The following is a script posted by masalaman over at vb.com. It does everything except shut down / open the boards:

#!/bin/sh
 
# List of databases to be backed up separated by space
dblist="testdb"
 
# Directory for backups
backupdir=/home/mysql/backup
 
# Number of versions to keep
numversions=4
 
# Full path for MySQL hotcopy command
hotcopycmd=/usr/bin/mysqlhotcopy
 
# MySQL Username and password
userpassword=" --user=root --password=password"
 
# Create directory if needed
mkdir -p ${backupdir}
if [ ! -d ${backupdir} ] 
then
	echo "Invalid directory: ${backupdir}"
exit 1
fi
 
# Hotcopy begins here
echo "Hotcopying MySQL Databases..."
RC=0
for database in $dblist
do
	echo "Hotcopying $database ..."
	$hotcopycmd $userpassword $database ${backupdir}
	RC=$?
	if [ $RC -gt 0 ]
	then
		break;
	fi
 
	# Rollover the backup directories
	i=$numversions
	mv ${backupdir}/${database} ${backupdir}/${database}.0 2> /dev/null
	rm -fr ${backupdir}/${database}.$i 2> /dev/null
	while [ $i -gt 0 ]
	do
		 mv ${backupdir}/${database}.`expr $i - 1` ${backupdir}/${database}.$i 2> /dev/null
		 i=`expr $i - 1`
	done
done
 
if [ $RC -gt 0 ]
then
	echo "MySQL Hotcopy failed!"
	exit $RC 
else
	# Hotcopy is complete. List the backup versions!
	ls -l ${backupdir}
	echo "MySQL Hotcopy is complete!"
fi
exit 0

Can this be modified to shut down / open the forums? Thanks much!
