The following diagram illustrates how data flows within the Druva setup at the time of hot restore.
Step 1
Druva Cloud initiates the restore request and forwards it to the Hybrid Workloads agent.Step2
Hybrid Workloads agent fetches the metadata from the storage in Druva Cloud.
Hybrid Workloads agent queries the TurboTier to restore the data.
📝 Note
If the connection to TurboTier 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 TurboTier to restore data. Ensure that the Hybrid Workloads agent can connect to Druva Cloud and TurboTier.
During a TurboTier disconnection, if a few data blocks remain in TurboTier and are not fully transferred/flushed to the Cloud, any attempts to restore a warm snapshot will fail.
