Create a Disaster Recovery Plan
1. Requirements and Compatibility
Supported VM Series
DRaaS is available for the following VM series:
| Series | Type |
|---|---|
| C3 | General-purpose compute |
| M3 | Memory-optimized |
| E1 | Economy |
Other VM series are not currently supported.
Supported Regions
DRaaS supports cross-region replication between E2E Networks data centers as follows:
| Source Region | Available Target Regions |
|---|---|
| Delhi | Chennai |
| Chennai | Delhi |
Source and target must always be different regions. Same-region DR is not supported.
Pre-conditions for Creating a DR Plan
Your source VM must meet all of the following before you can create a DR plan:
| Requirement | Details |
|---|---|
| VM is Running | Source VM must be in active running state. You cannot protect a stopped VM. |
| No encryption on disks | VMs with encrypted disks are not supported. |
| No auto-terminate enabled | If Reserved Instance auto-terminate is enabled, disable it first. |
| No scheduled power-off actions | Remove scheduled on/off automation before plan creation. |
| Block storage plans available | Attached block storage plans must be available in target region. |
| Sufficient infra credits | Account balance must be enough to cover DR plan cost. |
2. Getting Started Checklist
Before creating a plan, gather:
- Source VM you want to protect
- Target region (different from source)
- Desired RPO (1 to 240 hours)
- Desired retention period (1 to 365 days, default 7 days)
- Optional list of block storage volumes to include
3. Steps to Create a DR Plan
- From the sidebar menu, navigate to Disaster Recovery.
- Click Create Disaster Recovery.
- On the DR creation page, select the node to protect.
- Select volumes to include in DR (optional, recommended).
- Choose the target region.
- Configure RPO (1 to 240 hours).
- Configure Recovery Point Retention (1 to 365 days).
- Click Create Disaster Recovery and confirm in the popup.
4. Create a DR Plan from a Node
You can also create a DR plan from the Nodes page:
- Go to Nodes.
- Select the node to protect.
- Click Enable DR from the actions menu.
- You are redirected to DR creation page.
- Complete plan creation.
5. Target and Source Resource Nodes
Target Resource
- All actions on target node are restricted, except security group attach/detach.
- Security groups from source are automatically attached to target.
- SSH keys from source are automatically attached to target.
- Source start script is automatically applied to target.
Source Resource
- Source cannot be powered off unless DR plan is in Stopped state.
- Reinstallation is not allowed while DR plan is active.
- Moving resource to another project is not permitted while DR is active.
- Source resource upgrade and deletion are restricted during DR.
- You can start Recovery Mode only after stopping DR plan.
- Volumes can be attached to source once DR plan is stopped.
6. What Happens After Creation
After creation, plan enters Creating state. DRaaS then:
- Provisions standby VM at target region (same OS and SKU)
- Creates replica volumes at target and attaches them
- Clones security groups to target region
- Powers off target VM (standby mode)
- Triggers first data replication immediately
- Sets plan to Active state
This usually completes within a few minutes. A confirmation email is sent once plan is fully active and first recovery point is available.
7. Understanding Plan Status
| Status | Meaning | What You Can Do |
|---|---|---|
| Creating | DRaaS is setting up standby VM and first replication. | Wait and recheck. |
| Active | Replication runs on schedule and recovery points are generated. | Stop, delete, drill, recover, create manual recovery points, update settings. |
| Stopping | Replication is being paused. | Wait. |
| Stopped | Replication paused; no new recovery points. Existing points remain. | Start (resume) or delete. |
| Starting | Replication is being resumed. | Wait. |
| Starting DR Drill | DRaaS is restoring recovery points for drill prep. | Wait. |
| In Drill | Target VM is powered on for testing. | Stop drill when done. |
| Stopping DR Drill | Drill ending; target powering off; replication resumes shortly. | Wait. |
| Recovering | Recovery is in progress and target VM is being restored/powered on. | Wait. |
| Recovered | Recovery complete; target VM running in target region; DR plan ended. | Operate from target region. |
| Deleting | Plan is being removed; target VM and snapshots are being cleaned up. | Wait. |
| Deleted | Plan fully removed. | Create new plan if needed. |
| Failed | Creation or operation encountered unrecoverable error. | Contact support or create new plan. |
Action Blocking During Data Shipment
While replication shipment is running, these actions are blocked:
- Stop plan
- Delete plan
- Start DR drill
- Perform recovery
- Create manual recovery point
System message:
"Not allowed when data shipment is going on. Please wait."
Wait for shipment completion, then retry.
8. Important Notes
- Only running and available nodes can be included in a new DR plan.
- Nodes already part of an active DR plan cannot be reused in another plan.
- DR currently supports only C3, M3, and E1 non-encrypted nodes and non-encrypted volumes.
- DR creation is currently supported only between Delhi and Chennai regions.
