Snapshot Billing
Billing Rate
All snapshots are charged at a fixed rate of ₹0.0097 per GB per hour, regardless of their type (manual or scheduled) or location. Billing commences immediately upon snapshot creation and is calculated based on the total storage consumed. For incremental snapshots, billing is based on the size of the delta — that is, only the additional data since the last snapshot is charged.
Billing Example: How Snapshot Charges Work
The scenarios below illustrate how snapshot billing is applied based on user actions and data changes:
Case 1: User A Creates a Snapshot (S1)
- Action: User A creates a snapshot of their service.
- Snapshot Size: 100 GB
- Billing Start Time: Charges begin immediately upon snapshot creation.
₹0.0097 × 100 GB = ₹0.97 per hour.
Billing Overview:
| Snapshot ID | Size (GB) | Billing Rate | Cost Per Hour |
|---|---|---|---|
| S1 | 100 | ₹0.0097/GB/hour | ₹0.97 |
Case 2: Additional Data is Added and a New Snapshot (S2) is Taken
-
Action: User A adds 50 GB of additional data and creates a second snapshot.
-
Total Data in Snapshot S2: 50 GB, as it only includes the additional data. While the total data size of snapshot S1 remains 100 GB.
-
Snapshot S1: Continues to be billed as before:
₹0.0097 × 100 GB = ₹0.97 per hour. -
Snapshot S2: Billing starts immediately upon creation, but only for the additional data:
₹0.0097 × 50 GB = ₹0.485 per hour.
Billing Overview:
| Snapshot ID | Size (GB) | Billing Rate | Cost Per Hour |
|---|---|---|---|
| S1 | 100 | ₹0.0097/GB/hour | ₹0.97 |
| S2 | 50 | ₹0.0097/GB/hour | ₹0.485 |
- Both snapshots are billed in parallel for their respective data sizes.
Case 3: Deletion of Snapshot S1 by User A
-
Action: User A deletes snapshot S1. While this action stops billing for S1, but the data it contains is not lost. Instead, the data from snapshot S1 is combined to the next existing snapshot i.e. snapshot S2.
-
If there is no subsequent snapshot, billing will be only for active snapshots.
Post-Deletion Snapshot State:
• Remaining Snapshot: S2 with 150 GB (comprising 100 GB inherited from S1 and 50 GB of S2) and the billing for snapshot S2 for 150 GB will start just immediately after the deletion of snapshot S1.
₹0.0097 × 150 GB = ₹1.455 per hour
Billing Implication: Billing for Snapshot S1 stopped immediately upon deletion. However, because the data from S1 becomes part of snapshot S2, the billing continues for the full 150 GB of snapshot S2.
Billing Overview:
| Snapshot ID | Size (GB) | Billing Rate | Cost Per Hour |
|---|---|---|---|
| S2 | 150 (100 + 50) | ₹0.0097/GB/hour | ₹1.445 |
Note: Even though billing for snapshot S1 stops, the data it shares with snapshot S2 is still kept and charged under S2.
- Snapshot billing is incremental—charges are calculated per GB per hour.
- Multiple snapshots are billed in parallel for their respective data sizes.
Case 4: No Incremental Data Added Between snapshots
-
When no new data is added between snapshots, the incremental size of the subsequent snapshot will be 0 GB.
-
For example, continuing the scenario above, if User A takes a third snapshot (S3) after S2 without adding any new data to the service, the billing will be as follows:
- Billing for Snapshot S3:
₹0.0097 × 0 GB = ₹0.00 per hour
- Billing for Snapshot S3:
Billing Overview:
| Snapshot ID | Size (GB) | Billing Rate | Cost Per Hour |
|---|---|---|---|
| S2 | 150 | ₹0.0097/GB/hour | ₹1.455 |
| S3 | 0 | ₹0.0097/GB/hour | ₹0.00 |
This outcome results in no charge for snapshot S3.
Snapshot billing operates on an incremental charging model, meaning costs are applied only to the amount of data that has incrementally changed since the previous successful snapshot. Therefore, if the incremental size of the new snapshot is 0 GB, there will be no billed usage for that specific snapshot.
