The following diagram illustrates how data flows within the Druva setup at the time of hot restore.

Step Description

Step 1

Druva Cloud initiates the restore request and forwards it to the Hybrid Workloads agent.

Step 2

 
  1. Hybrid Workloads agent fetches the metadata from the storage in Druva Cloud.
  2. Hybrid Workloads agent queries the CloudCache to restore the data.

Note: If the connection to CloudCache is interrupted at the time of a backup, the Hybrid Workloads agent backs up data directly to the Druva Cloud. Since the deduplication data is available on the Druva Cloud, Hybrid Workloads agent requires a connection to Druva Cloud and CloudCache to restore data. Ensure that the Hybrid Workloads agent can connect to Druva Cloud and CloudCache. 

During a CloudCache disconnection, if a few data blocks remain in CloudCache and are not fully transferred/flushed to the Cloud, any attempts to restore a warm snapshot will fail.
