Using Virtualization, you can configure virtual machines (VMs) or instances for replication to one or more secondary sites and configure replication groups for Commvault Auto Recovery. Auto Recovery uses backups of primary VMs to create destination VMs and keeps destination VMs updated using continued incremental backups. Auto Recovery was formerly referred to as Disaster Recovery and Live Sync.
The Commvault software includes multiple auto recovery solutions. Choose the solution that most closely fits your needs based on your environment.

Solution
|
When to use
|
|
Orchestrated Recovery
|
-
This solution orchestrates one-click recovery of virtual machines using existing backups.
-
Applies to scenarios when you want to quickly recover VMs from backups.
-
The RPO that this solution uses is the frequency at which the backups are created.
|
|
Periodic Replication
|
-
This solution periodically creates and replicates new backups based on the frequency selected when creating a replication group.
-
You can orchestrate one-click recovery using the newly created and replicated backups. Applies to scenarios when you want to protect and recover VMs with reduced RPO at a higher frequency than compared to backup frequency.
-
The RPO that this solution uses is >15 minutes and is specified at the time of creating a replication group.
|
|
Continuous Replication
|
-
This solution allows you to use VMware VAIO to perform continuous block-level IO replication from a production site to a DR site. You can orchestrate one-click recovery using the recovery point created in the DR site.
-
Applies to scenarios that contain mission critical VMs that require continuous data replication to minimize RPO.
-
The RPO that this solution uses is < 15 minutes and is specified at the time of creating a replication group.
Note
The RPO will depend on the following:
-
The number of access nodes and their hardware specifications.
-
The IO throughput of the disks used for recovery point stores.
-
The amount of total data being replicated.
-
The bandwidth available for replication of data between the production site and DR site.
