How to exclude certain collections when creating a database dump?

Question

MongoDB

There is an old script found on the internet that backs up the mongodb database

#!/bin/bash
 
MONGO_DATABASE="collection"
APP_NAME="Name"

MONGO_HOST="127.0.0.1"
MONGO_PORT="27017"
TIMESTAMP=`date +%F-%H%M`
MONGODUMP_PATH="/usr/bin/mongodump"
BACKUPS_DIR="/var/www/backups/$APP_NAME"
BACKUP_NAME="$APP_NAME-$TIMESTAMP"
 
# mongo admin --eval "printjson(db.fsyncLock())"
# $MONGODUMP_PATH -h $MONGO_HOST:$MONGO_PORT -d $MONGO_DATABASE
$MONGODUMP_PATH -d $MONGO_DATABASE
# mongo admin --eval "printjson(db.fsyncUnlock())"
 
mkdir -p $BACKUPS_DIR
mv dump $BACKUP_NAME
tar -zcvf $BACKUPS_DIR/$BACKUP_NAME.tgz $BACKUP_NAME
rm -rf $BACKUP_NAME

find $BACKUPS_DIR -name "*.tgz" -mtime +7 -type f -delete

The problem is that I have resource-intensive collections in which some statistics are collected and I do not need to dump them, just like a collection with sessions, how can I ignore these collections when creating a dump?

sessions
analytics
counts

Or maybe there are some more flexible dump scripts?

--excludeCollection <name>
You can list more than one.
