Billing for EVS Snapshots

Legacy snapshots are in OBT. You can use them free of charge.

Standard snapshots are in commercial use. This section describes the billing of standard snapshots.

There are differences between legacy snapshots and standard snapshots. For details, see the snapshot constraints in Notes and Constraints.

Billing Items

EVS snapshots are billed based on the storage usage of snapshot chains and the usage periods. A snapshot chain collects the storage space used by data blocks of all the snapshots of a disk.

Instant Snapshot Restore is currently not billed. Snapshots with Instant Snapshot Restored enabled are only billed based on the storage usage.

Billing Modes

EVS snapshots support pay-per-use billing.

Pay-per-use is a postpaid payment model. Your snapshot is billed by the second, and you are billed for a minimum of 60 minutes each time. If the usage is less than an hour, you are billed based on the actual usage period consumed.

Billing Formula

Standard snapshot storage price = Snapshot unit price x Snapshot chain storage usage x Billed usage period

  • Snapshot unit price: The storage price per GiB per hour. The unit is $/GiB/hour. For details, see EVS Pricing Details.
  • Snapshot chain storage usage: The total storage space used by data blocks of all the snapshots of a disk. For details, see Calculating the Snapshot Chain Storage Usage.
  • Billed usage period: The billing starts after snapshots are created and ends after snapshots are deleted.

Billing example:

Assume that you created snapshots for a disk, the snapshots took up 100 GiB of storage, and you kept the snapshots for three hours. If the snapshot unit price was $0.000065 USD/GiB/hour, then the price of snapshots would be calculated as follows:

Snapshot storage price = $0.000065/GiB/hour x 100 GiB x 3 hours = $0.0195

Overdue Payment

If your account is not topped up after the account balance falls below zero, your account is in arrears and your pay-per-use snapshot will enter the grace period and retention period before being deleted.

  • During the retention period, if you top up your account, the snapshot will be unfrozen.
  • During the retention period, if you do not top up your account, the snapshot will be released after the retention period ends.
