Hi
We are setting up an EC2 access node in AWS to take backups from our Aurora Postgres estate. We use Amazon Linux 2 for all our EC2 deployments - but it seems for Aurora PostgreSQL its not supported.
Why is it OK for Aurora MySQL but not Aurora PostgreSQL??? It seems a bit odd that the linux OS offered by AWS wouldn’t be supported.
We would prefer to avoid RHEL as it would have cost / license implications (we use RHEL for on-prem deployments) and CentOS is a discontinued Linux distribution. Additionaly RHEL7 is a 10 years old OS that ends maintenance support in June 2024
We are extremely keen to avoid windows because:
(1) It stores Temp files on the access node will taking backup - (we are finding that failed jobs don’t clean up the temp files and eventually fill the temp space) - we want the data to just pass through the node - and not provision an expensive big EBS volume - we will be backing up multiple TB’s every night
(2) It involves extra annoying configuration from our end to join AD
