# Configure 1C database volume autoscaling

## How it works \{#principle-of-operation}

Autoscaling is available and enabled by default for Standard line configuration databases; if necessary, it can be [enabled](#enable-autoscaling) and [disabled](#disable-autoscaling) manually.

If the database volume reaches 80% capacity within 3 hours, a scaling task will be created to prevent downtime. The volume will be increased by 15% of its current size, but by at least 20 GB.

The scaling task will appear in the [Control panel](https://my.selectel.ru/ones/server): in the top menu, click **Products** → **1C Cloud** → **Databases** section → database page → **Maintenance** tab, and it will be performed during the next [maintenance window](/cloud-1c/cluster/maintenance-window.mdx). [Increasing the 1C database disk](/cloud-1c/database/resize-database.mdx) in the Control panel before scaling begins will cancel the task.

Autoscaling will disable automatically if the configuration is changed to the HighFreq line or upon reaching the maximum volume size of 1.23 To.

You cannot reduce the volume size after autoscaling, as this may compromise the integrity of the volume's file system and data — you can [create a new database](/cloud-1c/quickstart.mdx#choose-database-configuration) with a smaller volume.

## Enable autoscaling \{#enable-autoscaling}

1. In the [Control panel](https://my.selectel.ru/ones/server), on the top menu, click **Products** and select **Ready-made 1C Cloud**.
2. Go to the **Databases** section.
3. Open the database page → **Settings** tab.
4. In the **Disk autoscaling** row, click <EditIcon />.
5. Select the **Enable** checkbox.
6. Click <CheckIcon />.

## Disable autoscaling \{#disable-autoscaling}

1. In the [Control panel](https://my.selectel.ru/ones/server), in the top menu, click **Products** and select **1C Cloud**.
2. Go to the **Databases** section.
3. Open the database page → **Settings** tab.
