Restore a single database in Azure SQL Database to an earlier point in time using the Azure CLI

Applies to: Azure SQL Database

This Azure CLI example restores a single database in Azure SQL Database to a specific 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 a single database in Azure SQL Database to an earlier point in time

# Use Bash rather than Cloud Shell due to its timeout at 20 minutes when no interactive activity 
# In Windows, run Bash in a Docker container to sync time zones between Azure and Bash.

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-sql-rg-$randomIdentifier"
tag="restore-database"
server="msdocs-azuresql-server-$randomIdentifier"
database="msdocsazuresqldb$randomIdentifier"
restoreServer="restoreServer-$randomIdentifier"
login="azureuser"
password="Pa$$w0rD-$randomIdentifier"

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

echo "Creating $resourceGroup in "$location"..."
az group create --name $resourceGroup --location "$location" --tags $tag

echo "Creating $server in $location..."
az sql server create --name $server --resource-group $resourceGroup --location "$location" --admin-user $login --admin-password $password

echo "Creating $database on $server..."
az sql db create --resource-group $resourceGroup --server $server --name $database --service-objective S0

# Sleeping commands to wait long enough for automatic backup to be created
echo "Sleeping..."
sleep 30m

# 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 to $restoreServer"
az sql db restore --dest-name $restoreServer --edition Standard --name $database --resource-group $resourceGroup --server $server --service-objective S0 --time $restorePoint

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

Sample reference

This script uses the following commands. Each command in the table links to command specific documentation.

Command Description
