Rsnapshot: folder ownership permissions to 'backups' group instead of root

I am using rsnapshot to make daily backups of a MYSQL database on a server. Everything works perfectly except the ownership of the directory is root:root. I would like it to be root:backups to enable me to easily download these backups to a local computer over an ssh connection. (My ssh user has sudo permissions but I don't want to have to type in the password every time I make a local copy of the backups. This user is part of the *backups* group.) In /etc/rsnapshot.conf I have this line: backup_script /usr/local/bin/backup_mysql.sh mysql/ And in the file /usr/local/bin/backup_mysql.sh I have:

umask 0077
# backup the database
date=date +"%y%m%d-%h%m%s"                                                                                             
destination=$date'-data.sql.gz'
/usr/bin/mysqldump --defaults-extra-file=/root/.my.cnf --single-transaction --quick --lock-tables=false --routines data | gzip -c > $destination
/bin/chmod 660 $destination
/bin/chown root:backups $destination

The file structure that results is:

/backups/
├── [drwxrwx---]  daily.0
│   └── [drwxrwx---]  mysql [error opening dir]
├── [drwxrwx---]  daily.1
│   └── [drwxrwx---]  mysql [error opening dir]

The ownership of the backup data file itself is correct, as root:backups, but I cannot access that file because the folder it is in, mysql, belongs to root:root.
