Backup you on-prem/local #PostgreSQL database to cloud #AWS #RDS snapshot

backup for $0.026 + $0.125 per GB-month

Total costs of the backup operation: $0.026 + $0.125 per GB-month

Script below will do the following steps:

  1. create PostgresSQL AWS RDS t1.micro instance
  2. wait till instance started by using aws rds describe-db-instances
  3. get AWS RDS instance address
  4. copy database
  5. create AWS RDS instance snapshot and terminate instance by using aws rds delete-db-instance
  6. send notification by using AWS SNS service


_now=$(date +"%d%m%Y")

# create RDS instance
aws rds create-db-instance --db-instance-identifier $RDSINSTANCE --allocated-storage 5 --db-instance-class db.t1.micro --no-multi-az --engine postgres --master-username $DBADMIN --master-user-password $PGPASSWORD --db-name $DATABASE --backup-retention-period 0

# wait till instance started
while [ `aws rds describe-db-instances --db-instance-identifier $RDSINSTANCE | python -c 'import json,sys;obj=json.load(sys.stdin);print obj["DBInstances"][0]["DBInstanceStatus"]'` != "available" ]; do sleep 10; done

# get instance address
AWSHOST=`aws rds describe-db-instances --db-instance-identifier $RDSINSTANCE | python -c 'import json,sys;obj=json.load(sys.stdin);print obj["DBInstances"][0]["Endpoint"]["Address"]'`

# copy database
pg_dump -U postgres dbname=$DATABASE | psql --host=$AWSHOST --username=$DBADMIN --dbname=$DATABASE

# terminate instance and create snapshot
aws rds delete-db-instance --db-instance-identifier $RDSINSTANCE --final-db-snapshot-identifier $BACKUPNAME

# send notification
aws sns publish --topic-arn $SNSTOPIC --subject 'AWS RDS BACKUP' --message 'Done'

Cloud adds new statement to Manifesto for Agile Software Development

The cloud is not only a new way to more easily and cheaply get the computing power needed to do what companies and individuals are doing today…
This may be the most important benefit of the cloud—it enables companies of all sizes and in all sectors, as well as governments, non-profits, and individuals, to more quickly build new applications and services –

Cloud is agility and efficiency of computing. Agile team should be in the cloud.

It means that you should do your job completely in the cloud whenever possible. Developing, Testing, Presenting, e.t.c.
