The purpose of this article is to explain how Datto stores data in the cloud for both legacy and current products, as well as to clarify the important differences between the two methods.
The legacy G-Series devices offered a file based backup solution. A G-Series device simply stores a mirror image of its data in the cloud. Datto's current products, including the SIRIS, ALTO, and Datto NAS, use proprietary Inverse Chain Technology to take snapshot backups and retain archival data. The length of time that these archival backups are retained depends on the device's Cloud Billing Policy agreement. If you have questions in regards to your current cloud billing methods for any of your devices, those plans can be discussed with your Account Manager.
3. Cloud Storage Details
3.1. Cloud Storage with Current Datto Devices
The SIRIS, ALTO, and Datto NAS devices all provide archival storage of data in the cloud. This is extra insurance against data loss: Even if data is deleted from a SIRIS device, the data may still exist in the cloud, for a period of time determined by the device's Cloud Billing Policy.
3.1.1. Cloud Retention Settings
The cloud retention options for a device are set during deployment. To change these settings afterwards, connect to the Datto from the web interface. Click on an agent, and go to the Offsite Retention section, as shown in Figure 1. Once there, select the Offsite Retention section from the list on the left, as shown in Figure 1. To save these settings to the agent you selected, click the Apply button. To save the settings to all of the agents, click the Apply To All button.

3.1.2. Data Pruning
You may want to prune your cloud data for any of these reasons:
- Decommission a device or agent
- Re-purpose a device for another client
- Avoid getting billed for going over your cloud data limit, if applicable
3.1.3. Submitting a Prune Request
You can submit a prune request in one of two ways: an online form or a PDF. Simply follow the instructions given on the form. Please be as specific as possible as to what we need to prune and the reason for pruning. If you have questions about your cloud data usage, please contact us at Datto Technical Support. We can provide you a full summary of your data and cloud retention settings and guide you through the process of submitting a prune request, if necessary.
