Postgresus is a Free, open source and self-hosted solution for automated PostgreSQL backups. With multiple storage options and notifications. In this step by step guide I will show you how to install Postgresus on your Synology NAS using Docker and Portainer.

****

💡Note: This guide works perfectly with the latest Postgresus v1.27.2 release.

STEP 2

Install Portainer using my step by step guide. If you already have Portainer installed on your Synology NAS, skip this STEP. Attention: Make sure you have installed the latest Portainer version.

STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create two new folders and name the postgresus and postgresql. Follow the instructions in the image below. Note: Be careful to enter only lowercase, not uppercase letters.

STEP 4

Log into Portainer using your username and password. On the left sidebar in Portainer, click on Home then Live connect. Follow the instructions in the image below.

On the left sidebar in Portainer, click on Stacks then + Add stack. Follow the instructions in the image below.

STEP 5

In the Name field type in postgresus. Follow the instructions in the image below.

Note: Copy Paste the code below in the Portainer Stacks Web editor.

services:
db:
container_name: PostgreSQL
image: postgres
healthcheck:
test: ["CMD", "pg_isready", "-q", "-d", "marius_DB", "-U", "root"]
environment:
POSTGRES_USER: root
POSTGRES_PASSWORD: mariushostingroot
POSTGRES_DB: marius_DB
volumes:
- /volume1/docker/postgresql:/var/lib/postgresql:rw
ports:
- 2669:5432
restart: on-failure:5

postgresus:
image: rostislavdugin/postgresus:latest
container_name: Postgresus
healthcheck:
test: timeout 10s bash -c ':> /dev/tcp/127.0.0.1/4005' || exit 1
interval: 10s
timeout: 5s
retries: 3
start_period: 90s
ports:
- 4005:4005
volumes:
- /volume1/docker/postgresus:/postgresus-data:rw
restart: on-failure:5

Note: Before you paste the code above in the Web editor area below, change the value for POSTGRES_USER – root is an example for a username. You have to type in your own user. Note: Before you paste the code above in the Web editor area below, change the value for POSTGRES_PASSWORD – mariushostingroot is an example for a password. You have to type in your own password. Note: Before you paste the code above in the Web editor area below, change the value for POSGRES_DB and type in your own database name. marius_DB is an example for a database name. You have to type in your own database name.

STEP 6

Scroll down on the page until you see a button named Deploy the stack. Click on it. Follow the instructions in the image below. The installation process can take up to a few minutes. It will depend on your Internet speed connection.

STEP 7

If everything goes right, you will see the following message at the top right of your screen: “Success Stack successfully deployed“.

I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
