How to backup SQL Database [Simple ready to use script]

These are ready to use, simplest steps to start doing backups of SQL Database Server right now in the extra-cheap magnetic cloud storagešŸ“¼. Just set it up and test that backups are there.

Scheduler already inside, you don't need to setup cron jobs.

For best compatibility, we made our backup inside of docker container (source is hosted on github), so this guide also covers simple steps to setup docker if you don't have it yet.

To store backups we will use AWS S3 Glacier:

According to Glacier pricing it costs only $0.004 per GB / Month in US regions. If your gzipped database takes 100Mb you can create a backup every week, and after a year you will collect ~5.2Gb of data so it will cost you only $0.02 per month after a year.

With this price you will never want to delete backups - it is cheaper just leave them there forever. Glacier provides 99.999999999% durability of data which means you can always be calm - your data will be there. Glacier uses extra-cheap storages like magnetic tapes/compact disks, which are served by some robot and stored in special storerooms, that's why data retrieval time may take up to several hours.

      AWS_ACCESS_KEY_ID: "<access_key>"
      AWS_SECRET_ACCESS_KEY: "<secret_key>"

To get GLACIER_VAULT_NAME and AWS params see below.

Setup an AWS account and a Glacier bucket

1. Go to https://portal.aws.amazon.com/billing/signup#/start and create an account
2. Go to IAM Users and add a new user:

3. Type username and set api access:

4. Add GlacierFullAccess:


5. Next, Next, Create User
6. Show API Key ID and Secret and use them in docker-compose.yml file


7. Last thing, create a Glacier Vault. Go here and create a new one with Create Vault button. Remember vault name which you will enter to use it in docker-compose.yml. Also, we recommend creating a vault in US East (N. Virginia) regionšŸŒŽ.
