utiliser mysqlhotcopy

Bonjour à tous;


j'ai un probleme avec se script perl ;
le script est:

#!/bin/sh

#list of databases to be backed up separated by space
dblist="unicomm"

# Directory for backups
backupdir=/home/mysql/backup

# Number of versions to keep
numversions=4

# Full path for MySQL hotcopy command
hotcopycmd=/usr//local/mysql/bin/mysqlhotcopy

# MySQL Username and password
userpassword=" --user=root --password=123rr"

# 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



        # Hotcopy is complete. List the backup versions!
        ls -l ${backupdir}
        echo "MySQL Hotcopy is complete!"

exit 0
