A basic script to integrate `mongodump` and `mongorestore`.

mongo-dump_and_restore.rb

#!/usr/bin/env ruby

require 'date'
require 'fileutils'

app_key = ''

DUMP_HOST = 'localhost'
DUMP_PORT = '27017'

RESTORE_HOST = 'localhost'
RESTORE_PORT = '27017'

FileUtils.remove_dir("./dump", true)

ms = `date -j -f "%Y-%m-%d %H:%M:%S" "#{Date.today.to_s} 00:00:00"  "+%s"`.strip + '000'

puts "--> Date: #{Date.today}"
puts "\n--> mongodump start"

str = %Q(mongodump --host #{DUMP_HOST}:#{DUMP_PORT} --db error_type --collection error_types --query '{app_id: ObjectId("#{app_key}"), updated_at: { $gte: Date(#{ms}) } }')

system(str)

puts "\n--> mongorestore start"

`mongorestore --host #{RESTORE_HOST}:#{RESTORE_PORT} --db error_type --collection error_types ./dump/error_type/error_types.bson`
