APPLIES TO: Azure Database for PostgreSQL - Single Server Azure Database for PostgreSQL - Flexible Server

This sample CLI script restores a single Azure Database for PostgreSQL server to a previous point in time.

If you don't have an Azure subscription, create an Azure free account before you begin.

Prerequisites

Sample script

For this script, use Azure CLI locally as it takes too long to run in Cloud Shell.

Sign in to Azure

Use the following script to sign in using a specific subscription.

subscription="<subscriptionId>" # add subscription here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in interactively

Run the script

# Restore an Azure Database for PostgreSQL server

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-postgresql-rg-$randomIdentifier"
tag="backup-restore-postgresql"
server="msdocs-postgresql-server-$randomIdentifier"
sku="GP_Gen5_2"
restoreServer="restore-server$randomIdentifier"
login="azureuser"
password="Pa$$w0rD-$randomIdentifier"

echo "Using resource group $resourceGroup with login: $login, password: $password..."

# Create a resource group
echo "Creating $resourceGroup in $location..."
az group create --name $resourceGroup --location "$location" --tags $tag

# Create a PostgreSQL server in the resource group
# Name of a server maps to DNS name and is thus required to be globally unique in Azure.
echo "Creating $server in $location..."
az postgres server create --name $server --resource-group $resourceGroup --location "$location" --admin-user $login --admin-password $password --sku-name $sku

# Sleeping commands to wait long enough for automatic backup to be created
echo "Sleeping..."
sleep 10m

# Restore a server from backup to a new server
# To specify a specific point-in-time (in UTC) to restore from, use the ISO8601 format:
# restorePoint=“2021-07-09T13:10:00Z”
restorePoint=$(date +%s)
restorePoint=$(expr $restorePoint - 60)
restorePoint=$(date -d @$restorePoint +"%Y-%m-%dT%T")
echo $restorePoint

echo "Restoring $restoreServer"
az postgres server restore --name $restoreServer --resource-group $resourceGroup --restore-point-in-time $restorePoint --source-server $server

Clean up deployment

Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.

az group delete --name $resourceGroup

Sample reference

This script uses the commands outlined in the following table:

Command Notes
az group create Creates a resource group in which all resources are stored.
az postgresql server create Creates a PostgreSQL server that hosts the databases.
az postgresql server restore Restore a server from backup.
