This article provides step-by-step procedure to perform point-in-time recoveries in Azure Database for MySQL flexible server using backups.

Prerequisites

An Azure account with an active subscription.

If you don't have an Azure subscription, create an Azure free account before you begin. Currently, with an Azure free account, you can try Azure Database for MySQL - Flexible Server free for 12 months. For more information, see Try Azure Database for MySQL - Flexible Server for free.
Install or upgrade Azure CLI to the latest version. See Install Azure CLI.
Login to Azure account using az login command. Note the id property, which refers to Subscription ID for your Azure account.
```
az login
```
If you have multiple subscriptions, choose the appropriate subscription in which you want to create the server using the az account set command. `
```
az account set --subscription <subscription id>
```
Create an Azure Database for MySQL flexible server instance if you haven't already created one by using the az mysql flexible-server create command.
```
az mysql flexible-server create --resource-group myresourcegroup --name myservername
```

Restore a server from backup to a new server

You can run the following command to restore a server to an earliest existing backup.

Usage

az mysql flexible-server restore --restore-time
                                 --source-server
                                 [--ids]
                                 [--location]
                                 [--name]
                                 [--no-wait]
                                 [--resource-group]
                                 [--subscription]

Example: Restore a server from this 2021-03-03T13:10:00Z backup snapshot.

az mysql flexible-server restore \
--name mydemoserver-restored \
--resource-group myresourcegroup \
--restore-time "2021-03-03T13:10:00Z" \
--source-server mydemoserver

Time taken to restore will depend on the size of the data stored in the server.

Geo-Restore a server from geo-backup to a new server

You can run the following command to geo-restore a server to the most recent backup available.

Usage

az mysql flexible-server geo-restore --source-server
                                 --location
                                 [--name]
                                 [--no-wait]
                                 [--resource-group]
                                 [--subscription]

Example: Geo-restore 'mydemoserver' in region East US to a new server 'mydemoserver-restored' in its geo-paired location West US with the same network setting.

az mysql flexible-server geo-restore \
--name mydemoserver-restored \
--resource-group myresourcegroup \
--location "West US" \
--source-server mydemoserver

Perform post-restore tasks

After the restore is completed, you should perform the following tasks to get your users and applications back up and running:

If the new server is meant to replace the original server, redirect clients and client applications to the new server.
Ensure appropriate VNet rules are in place for users to connect. These rules are not copied over from the original server.
Ensure appropriate logins and database level permissions are in place.
Configure alerts as appropriate for the newly restore server.
