Simple script to backup MongoDB to S3, without waste diskspace for temp files. And a way to restore from the latest snapshot.

backup-mongodb-to-s3.sh

#!/bin/sh
set -e
HOST=localhost
DB=test-entd-products
COL=asimproducts

S3PATH="s3://mongodb-backups-test1-entd/$DB/$COL/"
S3BACKUP=$S3PATH`date +"%Y%m%d_%H%M%S"`.dump.gz
S3LATEST=$S3PATH"latest".dump.gz
/usr/bin/aws s3 mb $S3PATH
/usr/bin/mongodump -h $HOST -d $DB -c $COL -o - | gzip -9 | aws s3 cp - $S3BACKUP
aws s3 cp $S3BACKUP $S3LATEST

# Restore
echo -n "Restore: "
echo -n "aws s3 cp $S3LATEST - |gzip -d  | mongorestore --host $HOST --db $DB -c $COL - "

Hi,
How to solve error like Invalid endpoint: https://s3.US East.amazonaws.com

backup and restore works great for me. I just have one question - I have many databases and was wondering if there is a way to backup all databases without defining a list of databases? or recommendation to backup separately for restore purposes? whats the best practice
use to backup 10-12 databases via one script?

@anilbhanushali thanks for your comment. Does it restore into the same db as exported or it creates it with a new name?

How the script works with very large (~60-100 GB) collections dumps?

@innokentiyt It works ;-)
