MongoDBS3Backup

This script is based on the s3cmd

Setup

1. Register for Amazon AWS

2. Install s3cmd (following commands are for debian/ubuntu, but you can find how-to for other Linux distributions on s3tools.org/repositories)

    wget -O- -q http://s3tools.org/repo/deb-all/stable/s3tools.key | sudo apt-key add -
    sudo wget -O/etc/apt/sources.list.d/s3tools.list http://s3tools.org/repo/deb-all/stable/s3tools.list
    sudo apt-get update && sudo apt-get install s3cmd
   

3. Get your key and secret key at this link

4. Configure s3cmd to work with your account

    s3cmd --configure
   

5. Make a bucket (must be an original name, s3cmd will tell you if it's already used)

    s3cmd mb s3://mybucket
   

Now we're set. You can use it manually:

sh /home/youruser/backup.sh -d mydb -b mybucket

But, we don't want to think about it until something breaks! So enter crontab -e and insert the following after editing the folders

# daily backup to S3
0 3 * * * sh /home/youruser/backup.sh -d mydb -b mybucket
# weekly backup to S3
0 3 * * 0 sh /home/youruser/backup.sh -d mydb -b mybucket
# monthly backup to S3
0 3 1 * * sh /home/youruser/backup.sh -d mydb -b mybucket

And you're set.
