Script to restore all collections from mongodump

Feed this script the path to the dump directory created from mongodump to restore all collections. Handy to copy all mongo data to a new server.

#!/bin/bash

DUMPPATH=$1

if [ $# -ne 1 ] then
  echo "$0 "
  exit 1
fi

if [ ! -d $DUMPPATH ] then
  echo "$DUMPPATH is not a valid directory"
  exit 2
fi

# Preflight confirm
echo "************************************************************************************"
echo
echo "WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING"
echo
echo "This script will destroy ALL mongo data and refresh from the bson dump in $DUMPPATH"
echo
echo "Server: `hostname`"
echo "************************************************************************************"
echo

read -p "Are you sure you want to continue? (y/n)"

[ "$REPLY" == "y" ] || exit 0

# Iterate databases
for DBNAME in `ls "$DUMPPATH"`
do
  if [ -d "$DUMPPATH/$DBNAME" ]; then

    # Now iterate collections. We are only interested in .bson files
    echo "Restoring collections from $DBNAME db..."

    for FILENAME in `ls "$DUMPPATH/$DBNAME"`
    do
      EXT="${FILENAME##*.}"

      if [ $EXT == "bson" ]; then

        COLLECTION="${FILENAME%.*}"
        echo "Restoring ${COLLECTION}..."

        mongorestore --drop --db $DBNAME --collection $COLLECTION ${DUMPPATH}/${DBNAME}/${FILENAME}

      fi
    done

done

echo
echo "Restore complete"

exit
