| Restore a set of block blobs to a previous point in time. | Point-in-time restore<br />[Learn more...](point-in-time-restore-overview.md) | To use point-in-time restore to revert to an earlier state, design your application to delete individual block blobs rather than deleting containers. | A set of block blobs may be reverted to their state at a specific point in the past.<br /><br />Only operations performed on block blobs are reverted. Any operations performed on containers, page blobs, or append blobs aren't reverted. | No |

| Blob soft delete | No charge to enable blob soft delete for a storage account. Data in a soft-deleted blob is billed at same rate as active data until the soft-deleted blob is permanently deleted. |

| Point-in-time restore | No charge to enable point-in-time restore for a storage account; however, enabling point-in-time restore also enables blob versioning, soft delete, and change feed, each of which may result in other charges.<br /><br />You're billed for point-in-time restore when you perform a restore operation. The cost of a restore operation depends on the amount of data being restored. For more information, see [Pricing and billing](point-in-time-restore-overview.md#pricing-and-billing). |
105105
| Blob snapshots | Data in a snapshot is billed based on unique blocks or pages. Costs therefore increase as the base blob diverges from the snapshot. Changing a blob or snapshot's tier may have a billing impact. For more information, see [Pricing and billing](snapshots-overview.md#pricing-and-billing).<br /><br />Use lifecycle management to delete older snapshots as needed to control costs. For more information, see [Optimize costs by automating Azure Blob Storage access tiers](./lifecycle-management-overview.md). |

| Vaulted backup | For Vaulted Backup, You will incur backup storage charges or instance fees, and the source side cost ([associated with Object replication](object-replication-overview.md#billing)) on the backed-up source account. See [Pricing](../../backup/blob-backup-overview.md#pricing).|

| Copy data to a second storage account | Maintaining data in a second storage account will incur capacity and transaction costs. If the second storage account is located in a different region than the source account, then copying data to that second account will additionally incur egress charges. |
