Restore an Azure Database for MariaDB server using Azure CLI

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

If you don't have an Azure trail subscription, create a trial subscription before you begin.

Prerequisites

If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.

• If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.

• When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.

• Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.

Sample script

Sign in to Azure

Use the following script to sign in using a specific subscription. If you don't have an Azure trail subscription, create a trial subscription before you begin.

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 a server from backup to a new server

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="China East 2"
resourceGroup="msdocs-mariadb-rg-$randomIdentifier"
tag="backup-restore-mariadb"
server="msdocs-mariadb-server-$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 MariaDB 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 mariadb 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 mariadb server restore --name $restoreServer --resource-group $resourceGroup --restore-point-in-time $restorePoint --source-server $server

Clean up resources

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
