Amazon provides multiple options of database engine to use RDS. What makes it different from traditional databases is that it is very simple to set up, manage, and most importantly, it is scalable and provides high availability. Through this quick start gem, we can see how the AWS infrastructure can be leveraged with the advanced backup and restore features of EDB BART to simplify Postgres administrations tasks.Amazon RDS is a relational database and a web-based service. Run the SHOW-BACKUPS command to see information about for the backup: INFO: creating backup for server 'ip-172-31-62-18' Take a backup of the cluster using the BART BACKUP command: Verify WAL files are being archived the BART directory on EFS: INFO: setting archive_command for server 'ip-172-31-62-18' On EC2 instance 2, verify you can see the backups from instance 1 in a different availability zone: Verify WAL files are being archived to the BART directory on EFS $ psql -c "show archive_command" edb enterprisedb $ /usr/edb/as9.6/bin/pg_ctl reload -D $PGDATA Since archive_mode was previously on, the Postgres service just needs to be reloaded for the new archive_command to take effect: INFO: setting archive_command for server 'ip-172-31-25-184' Initialize the BART backup on EC2 instance ~]# su - enterprisedb

Install EDB BART and Mount the file system on your EC2 instances: Note: Later the BART INIT subcommand is used to modify the archive_command. Go to the EFS section of the AWS console to create a new file system:īe sure that the EC2 instances are in the same security group as the EFS mount point:īoth Postgres servers in this example are running with the basic configurations outlined in the EDB BART documentation.

Installation and Configuration Create an Elastic File Systemįrom the AWS console, this example has two running EC2 instances, each in a different availability zone in the us-east-1 region. If you are not already running BART, the documentation for version 2.0 is located here. However, EFS has several advantages over those solutions, the biggest being that the capacity grows and shrinks automatically as you add and delete files, and you only pay for the storage you are using. Operationally, Amazon EFS will remind you of file share solutions commonly found on-premise. If your organization uses EDB Postgres in Amazon Web Services and you want to leverage advanced EDB Backup and Recovery Tool (BART) features such as incremental backup, one way to accomplish this is with Amazon Elastic File System (EFS).
