You can perform the following to restore data on NAS shares:

A Hot recovery point restore is an on-demand restore of the server data that resides on CloudCache. Hot recovery points are point-in-time images of the backup data stored on CloudCache. Such a restore operation continues until Druva restores the data to the specified location.

📝 Note
​The CloudCache deployment is optional, and hence Hot recovery points are available for restores only when the environment has a CloudCache deployment.

In the navigation pane on the left, select the NAS device from the Device drop-down. On the NAS Shares page,click the share that has the data to be restored. In the NAS Shares details page, under Configured Backup Sets, select the backup set, and then click Restore. The Recovery pointViewer displays the date and timestamp of the latest recovery point. Click the drop-down next to it, click the Hot tab, and then select the recovery point that you want to restore from.

A Warm recovery point restore is restoring of point-in-time images of the backup data dating back to 90 days in time and stored in the warm storage. Such a restore operation continues until the server data is restored to the specified location.

In the navigation pane on the left, select the NAS device from the Device drop-down. On the NAS Shares page,click the share that has the data to be restored. In the NAS Shares details page, under Configured Backup Sets, select the backup set, and then click Restore. The Recovery pointViewer displays the date and timestamp of the latest recovery point. Click the drop-down next to it, click the Warm tab, and then select the recovery point that you want to restore from.

Cold recovery points are point-in-time copies of backup data older than 15 days. These recovery points are stored in the Amazon Glacier Deep Archive. To restore data from cold recovery points, data needs to be first retrieved from Amazon Glacier Deep Archive before a restore can be triggered. At the time of restore, data from the cold tier is retrieved, moved temporarily to the warm tier, and then restored. Once you click Restore and initiate the restoration process, the data retrieval from the cold tier and its restore from the warm tier happen automatically. Warmed up data is deleted from the warm tier after 10 days.

📝 Note
​Cold recovery points are available for restores, if the backup policy has LTR and Archive enabled. For more information, see Enabling Long Term Retention and Protect File Server and NAS data in Archive storage tier.

In the navigation pane on the left, select the NAS device from the Device drop-down. On the NAS Shares page,click the share that has the data to be restored. In the NAS Shares details page, under Configured Backup Sets, select the backup set, and then click Restore. The Recovery pointViewer displays the date and timestamp of the latest recovery point.

If your environment is infected with Ransomware, you can quarantine recovery points using Cyber Resilience. You can also quarantine the recovery points using the Quarantinerecovery points on a resource API. With Druva APIs, you can integrate Ransomware recovery with your existing security tools. You can also build custom scripts to automate action if there is a ransomware attack.

❗ Important

The availability of the ransomware feature in Cyber Resilience may be limited based on the license type, region, and other criteria. To access this feature, contact your Account Manager or Support.

Quarantined recovery points have a lock symbol next to them.

Druva allows you to view the data in the quarantined recovery point and delete such recovery points. However, you cannot restore files from such recovery points. To view a list of quarantined files, see Audit Trails.

If you select a file(s) from search results and that file(s) belongs to a quarantined recovery point, you will get the following error message.

For more information, see Ransomware Recovery for Servers

Recovery points are deleted from storage, after the duration in the retention settings has lapsed. There could be instances where the recovery points have been deleted manually. The metadata information might still reference files that are part of these recovery points. These files are still visible through search, but cannot be restored. To view a list of deleted files, see Audit Trails.

If you select multiple versions of a file and some of these versions belong to recovery points that are quarantined or deleted, Druva restores the files that can be restored. The list of all the quarantined and (or) deleted files that could not be restored is visible in the Audit Trails.

If all the files that you searched for and selected belong to recovery points that are quarantined or deleted or both, you are restricted from restoring them.

If your environment has infected resources, you can use Druva’s Ransomware Recovery feature to restrict these resources from interacting with other resources. However, there is always a risk that existing securely backed data might already be infected and when you restore such data, you run the risk of infecting the destination resource. This is where the Curated Recovery point feature comes in.
Curated recovery point is a unique version of recovery point that is a collection of the latest, safest, and most secure version of a file in a single recovery point. The curated recovery point is created by processing files from multiple recovery points within a specified date range. For more information, see Curated Recovery points.

After a curated recovery point is created for a NAS device, it is available for restore from the NAS Backup Sets page.
